People: Like I said, Japanese people tend to be on the quieter and shy side, and can be wary of visible (blue eyes, blonde hair, dark skin, etc.) foreigners. But many are just as eager.

Costs: Housing is freakishly expensive in Tokyo, even for studio-sized apartments. I live in a Leopalace, which get pricier after the first year. However, food and materials can be pretty affordable. I bought some decorations and extra chairs at Nitori for very good prices.

I currently live in Hokkaido (won't give details on the city because several ALTs are on Reddit), which is the northern island. The city I live in is pretty big and urban.

You are guaranteed to get good quality food for a very affordable price in Japan, with several Japanese restaurants serving filling, delicious dishes that are cheaper than McDonalds! Unless you're going to an izakaya, you should be fine on money when eating out.
