I've never really tried, but I say I could go for a few months, to a few years.

I don't know much about Japanese cusine, but I know one thing: Japanese food = seafood, and seafood is my comfort food. So I could live at least two months on a good sized bag of raw shrimp, and not be out of my comfort zone. After that, I would probably find some kind of other seafood-type meal to eat for the next few months. The only problems I would think I'd come across would be not being able to find or fix the food.

I could live for quite some time on Japanese food...
