NATIONAL INSURANCE GUIDE

Insurance in Japan for Americans and Expats

Insurance in Japan for Americans and Expats

Insurance in Japan mandates National Health Insurance (NHI) enrollment for all residents staying over three months, covering 70% of medical costs while requiring 30% patient co-payments through Japan’s universal Social Insurance System. Americans and expats face unique challenges: employer-provided Shakai Hoken (health + pension) for full-time workers, NHI for freelancers/students, and private international policies bridging coverage gaps during the initial 14-day registration period and supplementing NHI’s 30% out-of-pocket maximum. Visitor visa holders (<90 days) need short-term travel insurance, while long-term residents (E-2, L-1, student visas) combine public mandatory coverage with private augmentation for English-speaking doctors and direct billing. Premiums range ¥20,000–¥80,000/month NHI (income-based) plus $100–$400/month private.
