Japan Wanted Foreigners. Now It Is Deciding How Many Is Too Many.

For decades Japan insisted it was not an immigration country. Demographics made that position untenable, and the number of foreign residents passed four million. Now the question has stopped being rhetorical: in August 2026 a government expert panel began studying whether Japan should set a numerical ceiling on the foreign share of its population — with a basic policy due before April 2027.

Japan has always been a country of productive contradictions.

It is one of the world's most advanced economies and one of its fastest-shrinking. It depends on foreign workers and has spent forty years avoiding the word "immigration." It courted the world's travellers so successfully that it now taxes them to manage the crowds. It wants global talent while making several of the pathways that talent uses considerably harder to walk.

For most of that time the contradiction was survivable, because the numbers were small. They are not small any more.

The four numbers that define the debate

Those four lines contain the whole argument. Japan's foreign population grew nearly 10 percent in a single year (Immigration Services Agency). The country underneath it shrank by 3.1 million people in five years, with population falling in 1,558 of 1,719 municipalities — 90.6 percent of Japan (Statistics Bureau of Japan). And employers kept hiring, to a record 2.57 million foreign workers across 371,215 workplaces (Ministry of Health, Labour and Welfare).

So Japan needs more people, and is less and less certain how many of them should be foreign.

What changed in the last twelve months is that the Japanese state stopped treating that as a rhetorical question and started treating it as an arithmetic one.

Four million sounds enormous. Context matters.

Measured against the 2025 census, foreign residents are roughly 3.4 percent of people living in Japan. Australia's foreign-born share is 29 percent, Canada's 22 percent, Germany's 18 percent; the OECD average is 11 percent, and Japan sits with Poland, Türkiye and Korea in the small group of members below 4 percent (OECD, International Migration Outlook 2025). Japan has not become a country of mass immigration, and saying so is not a defence of anything. It is a precondition for arguing honestly.

One caution about that comparison, since it is the same trap this article warns about later. Most countries count the foreign-born, a group that includes people who have since naturalised. Japan and Korea count foreign nationals. Japan's measure is therefore the narrower one, and a like-for-like foreign-born figure would be somewhat higher — though nowhere near closing a gap of that size.

There is a second comparison Japanese readers make instinctively and foreign commentary almost never does: Japanese people leave too. As of 1 October 2025, 1,298,170 Japanese nationals were living abroad, essentially unchanged on the year, with 416,380 in the United States, 105,566 in Australia and 92,928 in China (Ministry of Foreign Affairs). About 22,000 Japanese citizens emigrated to OECD countries in 2023.

That does not rebut anything — 1.3 million Japanese abroad is not an answer to 4.1 million foreign residents at home, and treating it as one would be a debating trick. What it establishes is scale and direction. Japan receives roughly three times more than it sends, which means the country that spent the first half of the twentieth century exporting people to Hawaii, Brazil and Peru — the nikkeijin whose descendants it later invited back — is now firmly on the receiving side of the ledger.

The mirror is sharper still. Among Japanese abroad, those living overseas without a fixed term rose 1.4 percent to 588,486, while fixed-term stayers, the corporate postings and study placements, fell 0.4 percent. Settlement is quietly replacing rotation on both sides of Japan's border, and for the same unglamorous reason: people build lives where the work is.

The meaningful signal, then, is not the level. It is the speed, the composition and the direction.

Nepal passed 300,000 for the first time. Indonesia and Myanmar each added more people in one year than live in many Japanese cities. Korea — long one of the old faces of foreign Japan — shrank.

Tokyo alone hosts 801,438 foreign residents, 19.4 percent of the national total, though Osaka (+12.5%) and Saitama (+10.9%) grew faster last year than Tokyo did.

Read together, those numbers describe something more consequential than an influx. They describe a shift from temporary rotation to settlement: a stalled trainee programme, a booming skilled-worker route, and nearly a million people who already hold the right to stay indefinitely.

Japan needed workers long before it wanted immigrants

For most of the postwar era Japan ran a deliberate sleight of hand. It admitted foreign labour without conceding that it was building an immigrant society — trainees, students, spouses, nikkeijin descendants of Japanese emigrants — each category framed as an exception to a rule nobody stated out loud.

Demography ended the trick. The National Institute of Population and Social Security Research projects that Japan's population will fall from 126.15 million in 2020 to about 87 million by 2070 under the medium-fertility, medium-mortality scenario, dropping below 100 million in 2056. The share aged 65 and over rises from 28.6 percent to 38.7 percent (IPSS, 2023 revision).

That is not a labour-market cycle. It is a structural transformation, and it is visible in every sector where the work cannot be done remotely: construction, hospitality, food service, manufacturing, agriculture, logistics and above all nursing care.

Japan has real alternatives to immigration, and it is using all of them — automation, productivity, higher participation by women and older workers, wage increases, consolidation of small firms, pro-natal policy. None of them produces a working-age adult inside a decade. The labour statistics show what employers did while waiting:

• Professional and technical workers: 865,588 (+20.4% in one year)
• Status-based residents (permanent residents and family): 645,590
• Technical interns: 499,394
• Students and others working outside their status: 449,324
• Designated activities: 111,074 (+29.6%)

Vietnamese nationals alone account for 605,906 workers, 23.6 percent of the total, followed by China (431,949) and the Philippines (260,869). The sector growing fastest is medical and welfare work, up 25.6 percent.

Foreign labour is no longer an experiment at the edge of the Japanese economy. It is load-bearing.

The system changed before the vocabulary did

Here is the irony at the centre of the Japanese debate: Japan spent two decades building the machinery of an immigration country while refusing the word.

The Technical Intern Training Programme — criticised at home and abroad as a labour scheme wearing the costume of technology transfer — will be abolished and replaced by Employment for Skill Development (ikusei shūrō 育成就労) on 1 April 2027 under Act No. 60 of 2024. The new framework states plainly that its purpose is securing and developing workers, adds a Japanese-language requirement at entry, and permits job changes after one to two years, which the trainee system effectively forbade (JITCO; MHLW).

Alongside it, Specified Skilled Worker created durable pathways in labour-short sectors, the points system privileged the highly skilled, J-Skip and J-Find courted elite talent, and international students became a recruitment pipeline.

The consequences were entirely predictable. People stayed. Families formed. Children were born and enrolled in Japanese schools. Permanent residents approached a million. Companies restructured around foreign employees.

At which point the distinction between "foreign worker" and "immigrant" became a statement about Japanese vocabulary rather than about anybody's life.

Then the politics arrived

Immigration was not a decisive Japanese electoral issue until very recently. In the space of a year it became one of the organising questions of national politics.

July 2025: the breakthrough

In the Upper House election, Sanseito (参政党) — campaigning on a "Japanese First" platform and warning of a "silent invasion" — won 14 seats, taking it from one seat to 15 in the 248-member chamber (Reuters).

A qualifier most coverage dropped: immigration was not what most voters cared about. In NHK polling before that vote, 29 percent named social security and the declining birthrate as their biggest concern and 28 percent named rising rice prices. Immigration was in joint fifth place at 7 percent. A small but intense constituency, amplified online, moved the agenda far more than its raw ranking suggested. That is usually how realignments begin.

November 2025: the cabinet takes the file

Under Prime Minister Takaichi Sanae, the cabinet established the Ministerial Meeting on the Acceptance of Foreign Nationals and the Realisation of an Orderly Coexistence Society (外国人の受入れ・秩序ある共生社会実現に関する関係閣僚会議) on 4 November, with instructions to produce a governing philosophy rather than another round of ad hoc measures (Cabinet Secretariat).

January 2026: the package

On 23 January the council adopted the Comprehensive Measures for the Acceptance of Foreign Nationals and Orderly Coexistence. The document's own framing is that it introduces "order" (秩序) as an organising concept, in response to what it calls the public's anxiety and sense of unfairness. Its contents are concrete:

• a Zero Illegal Residents Plan and tougher action against illegal employment
• stricter screening of permanent residency and naturalisation
• a new pre-arrival and post-arrival Japanese-language and social-rules learning programme
• measures against unpaid medical bills
• tighter conversion of foreign driver's licences
• transparency over land and building ownership, including apartments and groundwater extraction
• a review of receiving caps in the Specified Skilled Worker and Employment for Skill Development systems
• higher residence and visa fees

February 2026: an election fought partly on this

In the 8 February general election the Liberal Democratic Party won 316 of 465 seats — the largest haul by a single party in the postwar era — and with Ishin's 36 seats the coalition controls 75.7 percent of the chamber. Sanseito went from 2 seats to 15, all through proportional representation. Both Ishin and Sanseito campaigned explicitly for a ceiling on the foreign population. The LDP manifesto did not mention one (Yomiuri; Jiji on the parties' positions).

July 2026: a deadline

At the council's third meeting on 24 July, the Chief Cabinet Secretary instructed ministries to accelerate: emergency staffing for the Immigration Services Agency, a summer package on land-acquisition rules, and — the decisive item — a basic policy on how many foreign nationals Japan should accept, to be compiled within FY2026, aligned with the national population strategy (Kantei).

August 2026: the arithmetic begins

On 7 August a six-member expert working group chaired by University of Tokyo vice-president Ōhashi Hiroshi held its first meeting. Its assignment is to project the foreign resident and foreign worker population to around 2040 under multiple net-migration scenarios, and to analyse the effects on the economy, social security, public safety and local communities. The LDP–Ishin coalition agreement commits the government to a population strategy including "quantitative management" (量的マネジメント) of the foreign resident ratio and caps. Minister for Coexistence Policy Onoda Kimi opened the session by noting that the foreign population is growing "faster than expected" (Asahi; Tokyo Shimbun / Kyodo).

This is the part of the story that most English-language commentary has not caught up with. "How many is too many" is no longer a columnist's framing device. It is an agenda item with a chair, a secretariat, a modelling methodology and a deadline.

The new message: contribution, documented

Long before any ceiling is decided, the criteria have already moved. Three changes show the philosophy.

The entrepreneur route

The Business Manager (経営・管理) status was among the most accessible in the developed world: roughly ¥5 million in capital, or two employees. Since 16 October 2025 an applicant must:

1. Hold ¥30 million in capital or invested business assets
2. Employ at least one full-time worker who is Japanese, a special permanent resident or a status-based resident
3. Demonstrate CEFR B2-level Japanese (JLPT N2 or equivalent) personally or through that employee
4. Hold a relevant graduate degree, or three years of management experience
5. Submit a business plan verified by a certified SME consultant, CPA or tax accountant

(Immigration Services Agency)

The capital figure gets the headlines, but the bundle is the real filter — particularly the language requirement, which quietly excludes a large share of would-be founders. ISA has also pushed back on the panic reading: existing holders are not required to produce ¥30 million or leave. Until 16 October 2028, failing the new bar is not by itself grounds to refuse a renewal, and even after that, sound finances, tax compliance and a credible path to compliance are weighed. Solid small businesses are not being expelled. The door for new arrivals has narrowed sharply.

Permanent residency

The ISA revised its Guidelines on Permanent Residence Permission on 24 February 2026 to state explicitly that the "national interest" test includes proper fulfilment of public obligations — tax, public pension, public health insurance and immigration notification duties — and, critically, that paying late counts against you even if everything is settled by the time you apply. The agency's stated reason is candid: it had seen applicants clear arrears to obtain permanent residency and then stop paying (ISA guidelines).

Then, on 4 August 2026, Justice Minister Hiraguchi Hiroshi announced a draft further revision, taking effect in stages from October 2026. It would require income above the average for a Japanese household of comparable size, projected pension entitlements equivalent to 30 years of employees' pension enrolment, and evidence that the applicant "actively and concretely brings benefits to Japan." The income test is reported to apply retroactively to applications filed since April 2026. Lawyers have already objected that requirements of this weight belong in legislation rather than administrative guidance; the labour and immigration lawyer Ibusuki Shoichi called it an encroachment on the Diet's authority (Jiji, 12 August 2026).

From April 2027, a three-year period of stay will no longer count as the "longest" period for permanent-residency purposes, and permanent residency becomes revocable for wilful non-payment of taxes and social insurance premiums under the 2024 amendment to the Immigration Control Act. Our rule-by-rule breakdown of that shift, including the fee increases and the spouse fast-track, is here: Japan's Permanent Residency Overhaul: Every 2026–2027 Rule Change.

Naturalisation

Here the direction is the same, and far less widely reported. The Nationality Act still requires, in principle, five years of continuous domicile. But the January 2026 package explicitly flags the "inconsistency" between that five-year rule and the ten years normally expected for permanent residency, and directs the Ministry of Justice to consider requiring, in principle, ten or more years of residence as part of the "integration into Japanese society" test.

Meanwhile the actual volume remains tiny. 9,258 people naturalised in 2025 out of 14,103 applicants — China 3,533, Korea 2,017, Nepal 695. In a country with 4.1 million foreign residents, fewer than ten thousand a year become Japanese.

The common thread across all three is not "foreigners are unwelcome."

What the data supports, and what it does not

There is nothing illegitimate about a state enforcing its immigration law, or about asking whether arrivals are outpacing the capacity of particular towns to absorb them. The failure mode is different: it is when a legitimate question about systems and behaviour silently becomes a claim about people.

Japan's own statistics are the best corrective, because they cut in both directions.

On enforcement, the numbers do not describe a state losing control. As of 1 January 2026 the ISA counted 68,488 overstayers, down 6,375 (−8.5 percent) year on year, with 9,748 newly identified. Overstayers fell across nine of the top ten nationalities. Short-term-stay overstays — visitors who did not leave — account for 41,607 of the total, which is a visa-screening and departure-management issue rather than a foreign-worker issue (ISA).

On crime, the honest reading is more uncomfortable and still not what the slogans claim. Clearances involving "visiting foreigners" (来日外国人 — a category that excludes permanent residents and special permanent residents) rose for a third consecutive year in 2025, driven heavily by organised theft and fraud networks, with Vietnam and China together accounting for about half. But Japanese crime rose too: nationwide, reported offences reached 774,142 in 2025 (+4.9 percent) and cleared persons 200,663 (+4.6 percent) — the fourth straight annual increase, now above pre-pandemic 2019 (National Police Agency).

Two things follow. Foreign-linked organised crime is a real enforcement problem that deserves resources and specificity. And the rise in Japanese crime is not explained by foreigners — which means a debate that treats the two as one phenomenon will misdiagnose both.

"Foreigners" are not one group

This is the single most important analytical point in the entire argument, and the one political language is least equipped to preserve.

A tourist spending five days in Kyoto is not an immigrant. A Vietnamese care worker is not a foreign investor. A Chinese doctoral student is not a permanent resident. A Japanese citizen born abroad is not a foreign resident at all. A highly skilled engineer is not economically interchangeable with a seasonal worker. A refugee applicant is not an overstayer. A permanent resident of thirty years is not the same social phenomenon as someone who landed last month.

Yet all of them can be collapsed into a single word — 外国人 — and once that happens, individual behaviour becomes collective evidence. A badly behaved tourist becomes an argument about care workers. One visa fraud becomes an argument about a million permanent residents. A single property purchase becomes proof of takeover.

The policy consequence is not abstract. Rules written against a composite villain land on real, different people, and they usually land hardest on the ones least able to absorb them.

Overtourism is real. It is not immigration.

Japan is absorbing two historic inflows at once, and conflating them is the most common error in the debate.

Inbound travel set a record in 2025: 42,683,600 visitors, up 15.8 percent and past 40 million for the first time, against 36,870,148 in 2024 (JNTO). In 2026 the curve has flattened — 21,084,800 in the first half, with June down 6.8 percent year on year (JNTO, June 2026).

Cities are responding with instruments aimed precisely at visitors. From 1 March 2026 Kyoto restructured its lodging tax into five bands topping out at ¥10,000 per person per night for rooms above ¥100,000 — a tenfold increase in the maximum and the highest fixed-rate lodging tax in Japan. The city expects revenue to roughly double, from ¥5.9 billion to about ¥13.2 billion, and is directing it at etiquette campaigns, cultural-property support, machiya preservation and transport pressure (Kyoto City). Other 2026 changes affecting visitors are collected in our guide to Japan's new rules for tourists.

That is what a targeted response looks like. A crowded bus in Higashiyama is an argument about transport capacity and visitor levies. It is not an argument about the pension record of a Filipino nurse in Gunma. When the two are argued as one problem, the likely outcome is that the tourists keep coming and the residents get the paperwork.

The official projections already assume immigration

Here is the fact that reframes the entire ceiling debate.

The IPSS projection that Japan's population "only" falls to 87 million by 2070 is not a no-immigration scenario. It assumes net inflows of non-Japanese nationals rising to 163,791 per year by 2040 and holding at that level. That single assumption is the main reason the projected decline slowed compared with the previous revision. On the same basis, foreign residents are projected to reach about 10.8 percent of Japan's population by 2070, up from 2.2 percent in 2020.

In other words, the official demographic baseline underpinning Japanese fiscal, pension and regional planning already presumes an immigration-dependent Japan — at a rate far below what has actually been arriving. Foreign residents rose by 356,418 in 2025; that is a stock change, not a net-migration figure, but it is more than twice the annual inflow the 2070 projection assumes from 2040. Suzuki Keisuke, the former justice minister, made the point in an August 2025 report: on current trends the 10 percent threshold arrives far sooner than 2070.

So a cap is not a return to a prior baseline. It is a decision to plan for a smaller Japan than the government's own projections currently assume. That is a legitimate choice. It is not a neutral one, and it deserves to be argued as a trade-off rather than a restoration.

Which leaves the unavoidable question in two forms:

Immigration cannot solve the population problem either

The honest counterweight: immigration is not a fix.

Foreign workers age. Migrants' fertility tends to converge toward the host society's. Sustained large-scale immigration would change Japan's cultural and political character — welcome to some, unacceptable to others, but not a technicality. And a policy that imports working-age adults while neglecting the schools, housing and language provision they need does not buy stability. It defers a bill.

Japan cannot say "we need workers, so open the doors" and expect the social arithmetic to take care of itself. It also cannot say "fewer foreigners, and everything returns to normal," because the Japan of 1990 no longer exists to return to. Both slogans are ways of avoiding a trade-off.

Not closing the door. Narrowing it, and adding a doorman.

Read as a whole, the 2025–2026 record does not describe a closing country.

Foreign workers hit a record. Specified Skilled Worker grew by more than 100,000 in a year. Employment for Skill Development arrives in 2027 with better mobility rights than the system it replaces. Student numbers are up. Investment promotion continues. The January 2026 package devotes entire chapters to Japanese-language education — before arrival, for workers, for residents, for children, and for the training and social standing of Japanese-language teachers.

At the same time: capital thresholds up sixfold, language tests where there were none, permanent residency priced and means-tested, naturalisation review lengthening, fees rising sharply, revocation powers arriving in 2027, and a formal study of quantitative caps.

That is not a shutdown. It is selection — and increasingly, selection on documented fiscal contribution. The state is asking: what do you do, what do you earn, do you pay on time, can you support yourself into old age, do you speak Japanese, are your children in school, and does Japan need you?

Most of those questions are defensible. Taken together — imposed through guidelines rather than legislation, and in one case retroactively — they also constitute one of the fastest redefinitions of settlement rights in any wealthy democracy right now, and it is happening with very little debate in the languages spoken by the people it affects.

The permanent-resident question is a question about belonging

Nearly a million people now hold permanent residency in Japan. They own homes, have Japanese spouses, send children to Japanese schools, pay Japanese taxes, work at Japanese companies and staff neighbourhood associations. Some have lived in Japan longer than many Japanese citizens have been alive.

For them the immigration debate is not about borders. It is about how long a person remains a foreigner. Five years? Twenty? Forty? A lifetime?

Japan offers two answers and is narrowing both. Naturalisation requires renouncing another nationality — and, if the current review proceeds, ten years of residence rather than five. Permanent residency preserves the original passport but is now conditional, priced, income-tested and revocable. Fewer than 10,000 people a year choose the first route. Nearly a million have chosen the second, and are watching the terms change beneath them.

A country can run that arrangement while the foreign population is small. It becomes considerably harder when a million long-term residents conclude that their permanence is provisional.

And then there are the children

The next generation is where the old model will break first.

Consider a child born in Japan to foreign parents. She speaks Japanese natively. Her friends are Japanese. She sat the same entrance exams, watched the same television, learned the same kanji. She may know little about her parents' country. Japan is not merely where she lives; it is where she is from.

Depending on her parents' status she may nonetheless spend her life categorised as foreign — and, under the draft permanent-residency rules, her school enrolment becomes a line item in her family's application file.

Multiply that across hundreds of thousands of families and the question changes shape. It stops being immigration policy and becomes a question about who counts as Japanese society in the twenty-first century. The answer will be given by administrative practice long before anyone legislates it.

The geography paradox

The foreign-resident story is not evenly distributed, and the distribution is politically inconvenient.

Tokyo, Osaka and Aichi hold the largest concentrations. But the sharpest growth rates in 2025 were in Osaka and Saitama, outpacing Tokyo — the metropolitan periphery and Kansai are densifying faster than the centre. And in the 1,558 municipalities that lost population between 2020 and 2025, foreign residents are increasingly the reason certain functions still exist at all.

A shrinking town has fewer Japanese children every year while foreign workers keep the factory running. A nursing home stays open because it recruited caregivers from Indonesia and Myanmar. A hotel in a tourist town depends on foreign staff to serve foreign guests. A farm brings in the harvest because someone arrived to bring it in.

Which produces the paradox worth sitting with:

Integration cannot mean only one side adapts

What can Japan reasonably expect? Learning Japanese. Paying taxes. Following the law. Understanding refuse rules and noise norms. Participating in the community. These are ordinary expectations and no one serious disputes them.

But expectation without provision is not a policy, it is a grievance.

• If the state wants Japanese-language ability, language education must be accessible and affordable — which is precisely what the January 2026 package promises, and which will be the fairest test of whether "orderly coexistence" means anything.
• If it wants taxes paid on time, notices must be comprehensible to the people receiving them, and guidelines that score late payment should be published in the languages of those being scored.
• If it wants labour law observed, it must be enforced against employers, not only against workers.
• If it wants community participation, communities need mechanisms for it.

The Japanese government's own document acknowledges this. It states that opportunities to learn Japanese and Japanese social norms are "not necessarily sufficient" at present, and that the receiving society has obligations too. That sentence is the most important one in the package, and the one least likely to survive contact with a budget cycle.

Japan has every right to decide. The question is how.

No serious person disputes that a sovereign state sets its own immigration levels, categories and conditions. Japan owes no one unlimited immigration, and no one is entitled to permanent residency merely for having entered legally. Tightening rules, enforcing tax law, punishing crime, preventing visa fraud, regulating land purchases and setting category limits are all legitimate exercises of sovereignty.

The tests that matter are procedural:

• Are the rules based on evidence, or on impression?
• Are they proportionate to the problem they name?
• Are they applied to individuals for individual conduct, or to categories by association?
• Are Japanese citizens and foreign residents held to comparable standards? A Japanese national with late pension payments loses no right to live in Japan.
• Are requirements of this magnitude properly enacted — by the Diet, prospectively — rather than imposed retroactively through guidance?
• Do they serve Japan's long-term interest, or this election cycle's mood?

Those are answerable questions, and they are the ones on which the current package should be judged.

The competitiveness risk is not hypothetical

Japan is competing for the same people as Singapore, Australia, Canada, Germany, the Gulf and the United States. Talent is mobile, and it reads rules.

The warning is now coming from inside the Japanese policy conversation rather than from foreign critics. Reporting the August 2026 permanent-residency draft, Jiji Press quoted the concern directly (Jiji, 12 August 2026):

When fees rise, thresholds move and the terms of settlement change retroactively while a cap is under study, the signal received abroad is not "Japan is orderly." It is "Japan is unpredictable" — and unpredictability is the one thing a mobile professional with a decade-long plan cannot price.

This matters more for Japan than for most countries, precisely because its demographics make each working-age arrival worth more. A policy designed to reassure domestic voters that the state is in control can simultaneously deter the exact cohort — high-earning, tax-paying, Japanese-speaking, long-staying professionals — that the new rules claim to prefer.

The real question was never a number

It is tempting to think a correct figure exists. Three million? Five? Ten percent?

A raw number tells you almost nothing. Five million foreign residents would be manageable if they were integrated, employed, geographically dispersed and supported by competent local institutions. Three million could be genuinely destabilising if concentrated in towns whose schools, clinics and housing stock were never funded for them.

So the honest version of the question the expert working group has been handed is not "how many foreigners can Japan tolerate." It is:

How many people can Japan integrate well — and is it willing to pay for the integration?

That question has an answer. It is simply more expensive than a ceiling, and much harder to put on a poster.

What to watch next

The bargain Japan has not yet named

Japan did not decide one morning to become an immigration country. It arrived here incrementally. A worker came. A student stayed. A company hired ten more. A nursing home recruited caregivers. A founder opened a business. A child was born. A family bought a house. A neighbourhood changed. Then the state looked up and counted 4,125,395 people.

Now it is asking a question it could have asked twenty years ago, and it is asking it with a deadline. But the number the working group produces will not settle anything, because the real issue was never capacity. It is whether Japan is prepared to treat foreign residents as permanent participants in Japanese society rather than long-term guests — and to build the schools, language programmes, labour enforcement and legal predictability that treating them that way requires.

Japan wanted foreigners. It wanted their labour, their skills, their taxes, their spending, their presence in the industries Japanese workers are no longer numerous enough to staff. It is now confronting the other half of that bargain.

If Japan wants foreigners to help sustain Japan, it has to decide what place they are permitted to occupy in the Japan they are sustaining. That is the question behind the headlines, and increasingly behind Japan's politics.

The number will come before April 2027. The harder question will outlast it.

FAQ

How many foreigners live in Japan in 2026?

Japan had 4,125,395 foreign residents at the end of 2025, the most recent official count, published by the Immigration Services Agency in June 2026. That is an increase of 356,418 people, or 9.5 percent, in one year, and the first time the figure has exceeded four million. Foreign residents are roughly 3.4 percent of Japan's total population of 123.05 million.

Is Japan going to limit the number of foreigners?

It is formally studying whether to. On 7 August 2026 a six-member government expert working group began analysing future foreign-population scenarios and the effects of foreign residents on the economy, social security and local communities. The LDP–Ishin coalition agreement commits the government to a population strategy including "quantitative management" (量的マネジメント) of the foreign resident ratio, and the government intends to compile a basic policy on the acceptance of foreign nationals within FY2026 — that is, by 31 March 2027. No cap has been adopted yet.

Is Japan becoming anti-foreigner?

The evidence is more specific than that. Foreign worker numbers hit a record 2.57 million in October 2025, the government's January 2026 policy package funds Japanese-language education before and after arrival, and overstayers fell 8.5 percent. At the same time, Japan has raised the Business Manager capital threshold sixfold, tightened permanent-residency criteria twice, is reviewing naturalisation, and is studying caps. The pattern is selective tightening on documented contribution and compliance, not closure — though the retroactive use of administrative guidelines has drawn criticism from Japanese lawyers.

Why does Japan need foreign workers?

Japan's population fell 3.097 million between 2020 and 2025 and is projected to reach about 87 million by 2070, with 38.7 percent of people aged 65 or over. Foreign workers now number 2,571,037 across 371,215 employers, concentrated in construction, manufacturing, hospitality, food service, agriculture and — the fastest-growing sector, up 25.6 percent in a year — medical and welfare work. Automation, higher participation by women and older workers, and pro-natal policy all help, but none produces working-age adults within a decade.

Do foreigners commit more crime in Japan?

Clearances involving "visiting foreigners" (来日外国人, a police category that excludes permanent residents and special permanent residents) rose for a third year in 2025, driven mainly by organised theft and fraud groups. But crime overall in Japan also rose: reported offences reached 774,142 (+4.9 percent) and cleared persons 200,663 (+4.6 percent) in 2025, the fourth consecutive annual increase. Foreign-linked organised crime is a genuine enforcement issue; it does not explain Japan's overall crime trend.

How many people become Japanese citizens each year?

About nine thousand. In 2025, 9,258 people were granted naturalisation out of 14,103 applicants, led by China (3,533), Korea (2,017) and Nepal (695). The Nationality Act requires five years of continuous domicile in principle, but the government's January 2026 package directs the Ministry of Justice to consider requiring ten or more years as part of the test of integration into Japanese society.

Is immigration the top political issue in Japan?

Not for most voters, though it has become far more prominent. In NHK polling before the July 2025 Upper House election, immigration ranked joint fifth at 7 percent, behind social security and the birthrate (29 percent) and rising rice prices (28 percent). It became a significant issue in the February 2026 general election, when Ishin and Sanseito campaigned for a ceiling on the foreign population while the LDP — which won a postwar-record 316 seats — did not commit to one.

A note on categories. "Foreign residents," "foreign workers," "visiting foreigners" (来日外国人), "inbound visitors," "overstayers," "permanent residents," "naturalised citizens" and "immigrants" are not interchangeable statistical categories, and the agencies that publish them use different denominators, reference dates and exclusions. The police category 来日外国人 excludes permanent residents and special permanent residents; the MHLW worker count excludes special permanent residents. In international comparison the same problem recurs: most OECD members report the foreign-born population, which includes naturalised citizens, while Japan and Korea report foreign nationals only. This article keeps them separate deliberately, because conflating them is the single most common way Japan's immigration debate is misunderstood — in Japanese and in English alike.
