Hello Shiho! I think that Japanese people that I have met are very nice and polite in my opinion.

Hi, Jasmine. Thanks for your comment. I see.

I think it is more depending on how you compare it with other languages. Compared to English it is. It also depends on what forms you use. Like if you say: *名前*です。 vs. *名前*ともします。 or 店にいけ！(very impolite) or 店に行きまして下さい(polite).

Thank your for your opinon! Really?! I am hapy to hear that. I think that in every culture politeness is needed.

surely! We, brazilian people, have special admiration about your politeness and good ways.
