Working in Japan

Wages just had their biggest jump in Japanese history, but hiring still runs on seniority and the job market for experienced foreign hires narrows fast without conversational Japanese.

Minimum wage just had its biggest jump ever

Following the October 2025 revision, Japan’s national average minimum wage rose to ¥1,121/hour — the largest single increase since the system began — and for the first time all 47 prefectures now sit at or above ¥1,000/hour. Tokyo and Kanagawa lead at ¥1,226 and ¥1,225; Osaka sits at ¥1,177; Kochi, Miyazaki and Okinawa trail at ¥1,023. The gap between Tokyo and the cheapest prefectures has narrowed but still shapes where entry-level and part-time (arubaito) work pays best.

Shakai Hoken: the deduction every payslip carries

Any company with 5+ employees (or any incorporated business) must enrol staff in Shakai Hoken — combined health insurance and Employees’ Pension. Under the Japan Health Insurance Association (Kyokai Kenpo) standard plan, the combined premium runs roughly 28.3% of salary — about 10% for health insurance and 18.3% for pension — split 50/50 between you and your employer. On a ¥300,000 monthly salary, that’s roughly ¥43,000 deducted from your pay, matched by an equal employer contribution. It funds real benefits (the 70/30 health cost split, and pension credits that count even for foreign residents who later leave — a lump-sum withdrawal payment exists for those who do).

Unemployment insurance (koyou hoken)

A smaller, separate premium (roughly 0.6% from the employee) funds koyou hoken, which pays benefits if you’re laid off or your contract ends, provided you’ve been enrolled long enough (generally 12 months within the prior 2 years, less for involuntary separation). Benefit duration and amount scale with age and length of employment — this is a real safety net, but it assumes you were on a work-eligible visa status the whole time.

Seniority still shapes the ladder

Traditional nenkou joretsu (seniority-based pay and promotion) has weakened, especially at foreign-capital firms and in tech, but it still visibly shapes salary bands and career expectations at traditional Japanese companies. The bigger practical obstacle for incoming professionals is that Japan’s hiring culture is still built around shukatsu — a single annual hiring cycle (April intake) designed for new graduates — which makes ad-hoc mid-career hiring (chuto saiyo) feel slower and less predictable than in most Western markets, even though it is a fast-growing channel, especially in IT.

Language is the real gatekeeper

Without at least JLPT N2-level Japanese, non-technical office roles narrow sharply; your realistic options cluster around English teaching, IT (where English-only teams exist at some firms), finance, and foreign-capital ("gaishikei") companies that operate in English. Technical roles in software engineering are the most forgiving of limited Japanese, particularly at larger multinationals with Tokyo offices.
