Do You Need Travel Insurance for Japan?

Almost never for routine or planned care, and rarely even for emergencies. Most US private insurance and Medicare do not cover treatment outside the United States. Some premium credit cards include limited emergency medical coverage, check your specific card's benefits guide before assuming you're covered.

Roughly 4-8% of your total trip cost for a comprehensive plan covering medical, evacuation, and trip cancellation. A $4,000 trip might cost $160-320 to insure, depending on your age and coverage limits.

No, it is not a visa or entry requirement for US or Canadian tourists. It is strongly recommended regardless, since healthcare costs without insurance can be significant and some clinics may ask about coverage before non-emergency treatment.

Yes, if you can afford it. Most people never need it, but evacuation from a remote area like rural Hokkaido or a small island to an appropriate hospital, or repatriation for a serious condition, can cost tens of thousands of dollars without coverage.

Most comprehensive policies do, provided the illness is not a pre-existing condition you didn't disclose, or you bought the "cancel for any reason" upgrade, which costs more but covers a wider range of reasons.

Less extreme than the US in absolute terms, but still significant. A multi-day hospital stay can run several thousand dollars, and specialist care or surgery costs more. Many hospitals expect payment at the time of treatment from uninsured foreign visitors.
