The Specified Skilled Worker programme has expanded dramatically since 2022, and its Category 2 conversion track is changing where migrants actually settle in Japan.
Japan's Specified Skilled Worker programme — Tokutei Ginō, or SSW — was introduced in April 2019 with a target of 345,000 admissions across its first five years and a scope limited to 14 sectors where domestic labour shortages were considered acute. By early 2024, the programme had clearly missed its original annual targets but was structurally reshaped through two policy moves that materially altered its character: a dramatic expansion of its Category 2 (permanent-track) provisions in April 2024, and a broader sectoral expansion announced in March 2024 that brought the covered sectors to 16 and raised the five-year ceiling to 820,000.
The structural distinction between SSW Categories 1 and 2 is worth understanding clearly. SSW Category 1 (Tokutei Ginō 1-gō) is a renewable visa for up to five years in total, tied to a specific sector, requiring Japanese language at the N4 level and passing a sector-specific skills test. It does not permit family accompaniment and does not lead directly to permanent residency. SSW Category 2 (Tokutei Ginō 2-gō) is the permanent-track visa: indefinite renewal, family accompaniment permitted, a path to permanent residency after the usual qualifying period, and higher language and skill thresholds.
Prior to 2024, Category 2 was restricted to two sectors (construction and shipbuilding) and served a tiny applicant population. The April 2024 expansion opened Category 2 to most of the remaining SSW sectors — food service, manufacturing, agriculture, automotive, aviation, lodging, and several others — subject to qualifying tests. The policy effect has been to offer Category 1 workers a genuine conversion pathway that retains them in the Japanese labour market long term rather than forcing their departure at the end of the five-year cap.
The Immigration Services Agency's cumulative SSW statistics through the end of 2024 show approximately 300,000 total SSW residents in Japan, a number that has been accelerating: the programme added roughly 90,000 residents in calendar year 2024 alone. Of this total, the vast majority remain in Category 1; Category 2 transitions are still in their early phase, with Immigration Services Agency figures suggesting around 15,000 cumulative Category 2 holders by end of 2024. That number is expected to grow substantially through 2026 and 2027 as Category 1 holders reach conversion eligibility under the expanded rules.
By origin country, the SSW programme has been dominated by Vietnam (approximately 35% of cumulative residents), Indonesia (approximately 18%), and the Philippines (approximately 17%), with the remainder dispersed across Myanmar, China, Nepal, Cambodia, Thailand, and others. The sectoral distribution is top-heavy: food service, industrial manufacturing, and agriculture together account for more than half of all Category 1 holders.
The regional-dispersion story is where the SSW data gets interesting. Tokyo and the three surrounding prefectures (Kanagawa, Saitama, Chiba) retain a plurality of SSW holders but not a majority — a striking difference from most skilled-migration patterns in advanced economies, where capital-region concentration is typically greater. Fukuoka Prefecture, on Kyushu, has emerged as the second-largest SSW-receiving region. Fukuoka Prefectural Government data through 2024 shows approximately 22,000 SSW residents in the prefecture, with particular concentration in the agricultural, food processing, and care sectors. The trajectory has been steep: Fukuoka's SSW population has roughly doubled since 2021.
Why Fukuoka? Three factors compound. First, Kyushu's agricultural and food-processing sectors are structurally among the earliest Japanese sectors to face acute labour shortages, and the SSW programme's sector design tracks these shortages closely. Second, Fukuoka Prefecture has actively operated a foreign-resident integration programme — through support centres, language programmes, and employer-matching infrastructure — that is more developed than in most other Japanese prefectures. Third, cost of living in Fukuoka remains meaningfully below Kansai and Kanto, which matters for workers at the wage levels the SSW programme generates. Fukuoka's rent index through 2024 sits at roughly 55–60% of Tokyo's; wages in the sectors SSW populates are closer to 80–85% of Tokyo equivalents. The compression improves the real-wage trade-off for workers weighing where in Japan to take an SSW placement.
A second-order effect the SSW expansion has generated is on Japan's long-term migration trajectory more generally. Japan's total foreign-resident population crossed 3.8 million for the first time in 2024, against a peak of approximately 2.9 million in 2020 before the pandemic-era collapse. The SSW programme is a meaningful but not dominant contributor to this growth — Technical Intern Training Programme residents and engineer/specialist visa holders remain larger cohorts — but the SSW is distinctive in combining acceleration with sectoral breadth.
What the SSW has not yet resolved is the question of long-term social integration. Category 1's prohibition on family accompaniment has produced a large population of male workers separated from their families for five-year periods, a pattern that advocacy organisations and sector analysts have criticised on both humanitarian and programme-retention grounds. Category 2's family accompaniment provision partially addresses this but only for workers who successfully convert, which requires language and skills thresholds that not all Category 1 workers meet in time. The Japanese political consensus on this has been slow to evolve; the 2024 expansion moved the structural answer but left the integration answer largely in place.
For a prospective SSW applicant in 2026, the programme is now genuinely different from what it was in 2022. The Category 2 expansion has transformed SSW from a time-limited labour-import scheme into a potentially-permanent migration pathway for workers in qualifying sectors who meet the conversion criteria. The sectoral breadth continues to widen. And the geographic pattern of where SSW workers actually live has continued to shift outward from Tokyo, with Fukuoka the leading example but not the only one. The programme's trajectory through 2026 and beyond is the single most important Japanese labour-migration story, and its evolution is likely to accelerate rather than plateau.
