Are there a lot of Indians in Japan and how hard is it for a vegetarian to live in Japan?

Question:

I am just wondering, Japan is such an amazing country; I would really consider living there in my future :)

Answer:

Anywhere there are lots of Buddhists, there are lots of vegetarian options. (just be sure there's no fish sauce in restaurants because some people innocently believe that fish is vegetarian).

Many Buddhists are vegetarian =)
