I like Japanese food. For example: sushi, rice ball, and sugared red beans. But I don't like wasabi. Many people like wasabi. It goes with sushi and meat. The rest of my family likes wasabi so I don't understand why I don't like it. It is very spicy to me. Sometimes it is seen as childish to not eat wasabi. My younger sister often tells me "you are child-like"(you could say "you are being childish"). I want to enjoy eating Japanese food more.

I could understand everything you were saying, I just corrected it to sound more natural. Good luck learning English! :)
