Does Japanese Health Insurance Cover Prescriptions?

Yes. Both of Japan's health insurance systems - Employees Health Insurance (社会保険, shakai hoken) and National Health Insurance (国民健康保険, kokumin kenko hoken, often shortened to NHI) - cover prescription medicine dispensed against a valid shohosen at the same rate they cover doctor visits. For most adults ages 6 to 69, insurance pays 70 percent and you pay a 30 percent co-pay at the pharmacy counter. It isn't a reimbursement you claim later - the discount applies automatically when you show your insurance credential, so you only ever hand over the co-pay amount. What's excluded: anything bought without a prescription, plus a short list of prescribed items like contraception, covered below.

Health insurance in Japan is universal and mandatory for anyone with a residence status over 3 months, and it runs through one of two systems. Employed by a Japanese company: your employer enrolls you in shakai hoken automatically. Not employed - self-employed, a student, between jobs: you enroll yourself in kokumin kenko hoken at your ward office. Neither is a lesser option; prescription coverage and the co-pay structure are identical either way. Only enrollment and premium calculation differ.

If NHI applies to you, enroll at the ward office within 14 days of your move-in registration (転入届) - the same clock that governs registering as a resident. Premiums are based on your previous year's Japan income, which for most new arrivals is low or zero, keeping first-year premiums modest.

Coverage attaches to prescriptions dispensed against a valid shohosen (処方箋). A few things fall outside that, regardless of which system you're on:

• OTC purchases - anything bought over the counter at a drugstore without a prescription is self-pay, full stop.
• Oral contraceptives for birth control - legal and prescription-required, but self-pay when prescribed for contraception.
• Prescriptions filled without your credential shown - the discount only applies when it's presented at the time of dispensing, not claimed back later.

Weighing what a prescription costs with no coverage at all - a lapsed enrollment, a tourist visit, a forgotten card? See filling a prescription without insurance in Japan. And if a month of treatment runs high even at 70 percent covered, a separate benefit caps your monthly out-of-pocket total - see the high-cost medical expense benefit.
