>>85624607If you are white and not fat and loud, you will be treated like a signpost at worst, most likely as politely as usual, and if you know any Japanese or are very handsome, will probably get Japanese people asking to chat with you.
Just start working on words and phrases at least, that way you can communicate something you need. 必要 and 欲しい might be helpful alongside the obvious sumimasen, arigatou gozaimasu, domo, gochisousama, etcetera. If you come for Fes you can roll with anons and our collective Japanese might be enough for a complete sentence!
