How much time have you spent in Japan???? I can guarantee that they aren't as bad to foreigners as you claim, clueless as to where you even got that idea from. They are pretty friendly people.

You can go do a quick Google search and read multiple blogs about people who've traveled there and loved it and the people there as well.

The language isn't "very difficult" either, most people just make that assumption because it's their first time seeing a language style like that. It's exactly like learning another language, start from the bottom with the beginner stuff and keep slowly advancing and it's very easy to understand.

People saying it's difficult would most likely struggle with learning other languages as well, some people are just good with this sort of stuff and others aren't.
