Gaijin here

1, Who are the rappers rapping for ages deep into the night on the corner of that street in Kyoto?

2. Why do the bookstores and crap look like they have young people anime pornography and how (and is?) that legal?

3. Is it safe to go into those girl bars and clubs where it looks like no one actually goes in, but fancy people outside encourage randoms to go in (except gaijin)

4. Is it safe to go into the bars in Shinjuku, Tokyo, that look like they are home to Yakuza? I want to meet Yakuza and have fun with them, but do they speak english?
