Japan's healthcare system, finally explained.
Clear, medically accurate guides for foreign residents — written by a doctor who works inside the system every day. No insurance sales. No sponsored clinics. Just what you need to know.
What will it actually cost you?
Out-of-pocket estimates for visits, scans and hospital stays — by insurance type and income, with the monthly ceiling built in.
Which doctor do I need?
Tap your symptom, get the right clinic type — with its Japanese name and the exact phrase to say at reception.
Can't say it? Show it.
Tick symptoms, allergies and medications in English — print a bilingual card to hand to any clinic reception.
Your medicine, in Japan
Type Tylenol, Nurofen or melatonin — see the Japanese equivalent, its OTC status, and what to say at the pharmacy.
Your blood pressure, charted
A home BP & pulse diary that lives only on your phone — trend chart, Japanese thresholds, and a printable log your 内科 doctor can read at a glance.
What did the doctor give me?
Paste the katakana from your medicine sheet and see what each drug is, what it's for, and its US / UK / Australian name — or that it isn't sold there. Nothing leaves your phone.
What do my checkup numbers mean?
Type the values from your 健康診断 sheet — LDL, HbA1c, liver enzymes, eGFR and more — and see the A–D letter each one gets, what it means, and which clinic to visit. mg/dL or mmol/L.
Your whole history, on one page
Allergies, medicines, conditions, surgeries, family history — written once, kept on your phone, shown or printed in Japanese and English at any clinic. The one page a Japanese doctor actually reads.
