Title: [jp] Add more Japanese rules

These are derived from the "問題な日本語、続弾" book.

Ideally we would have some native speakers check them as well but since they are derived from a grammar book they should be mostly fine. Additionally, these are very "safe" rules since they are very specific and deal mostly with misused characters.
