Yes, You can get travel insurance in Japan.
We recommend buying travel insurance if you don’t have it before arriving in Japan. Have to be sure to get a policy that covers full payments medical care. You can buy also lost luggage, cancelled hotel and plane tickets, and damage or stolen gear but cost will be expensive for sure.
We recommend Japanese company travel insurance when you staying Japan because other company insurance pays you after back home & you have to pays first. Also, you don’t know you will get money back for sure later.
Our insurance pays your bill to Hospital direct & Doctors offer the latest and best treatment. Because there is no worry about the treatment cost.
Some tourist go home without payment.
