Has anybody ever bought this kind of insurance in Japan? it's an insurance that will reimburse your plane ticket in case you can't go on your trip because of an illness or an accident. It's pretty standard in the US, Europe, Australia, etc...but it doesn't seem to exist in Japan (for example expedia has it but the Japanese version doesn't). Any tips welcome (btw I don't have a credit card...).
