how long ? not very
 

I lived in europe for a few years (not japan) I found that I could go about 1 day befor I started to crave my own style of food .:ywave:

Most of the food i eat everyday is japanese, i wouldnt survive without a bowl of rice. And i dont really care for american much anyway. So yeah it wouldnt bother me at all.

Very easily as i have had to do it before. So it wouldn't be a big deal for me to do it again.

propbally a month, but my tummy will be screaming for mexican food the whole time

i put years

food is food to me. it's all calories which i can burn for fuel
i can eat about anything and everything

I find it very interesting that more than 50% of JF thinks they could go for years without eating food from their own culture.

Frankly, MMM, I don't believe it myself. What is the percentage of JF that has actually been to Japan and tried this?

I have enough trouble making myself eat healthy. If I limited myself to 和食 (washoku, Japanese food, for those that cannot read kanji, sorry guys, force of habit), I'd be batty within a month, or just eating the same stuff over and over and over again, which would get boring.

Depends if people consider the question to mean 和食 or more generally just "could you survive on just what you can get in Japan, or would you have to brings stuff from home/import it," which are two different questions. Where does it end anyway? Is toast considered 'not japanese'? Spaghetti is no more natively part of the japanese diet than it is part of the British diet, and yet both nations eat a lot of it. 和風spaghetti? Is mosburger outside of the realm of 'Japanese food'? Idek.

Could I live on just what is generally available in Japan? Sure, excepting the tea issue, I could easily go for months before I wanted something I could only get outside of Japan. Wouldn't stop me from cooking 'japanese' ingredients in a western style. Could I eat 和食 day in day out, with traditional style breakfasts and absolutely nothing that didn't come into Japan post meiji? Maybe for a week or two. But then I doubt a lot of Japanese people do that constantly either.

I meant this. Week tops for me.

I think the reality is that many of the people that think they could go for years without eating food from their own culture have never spent much time away from their culture.

I thought my question was pretty clear. It depends on where you are, but there are few things that are not available on one way or another in Japan. Certainly bigger cities will have more variety, but pretty much everything is available. If it is necessary to be more clear, typical Japanese meals, 和風 is what I am talking about. Rice, misoshiru, fish, etc. I think you get the picture.

Really? Why would you doubt that?
