There is a tabelog app in Japan, which supports online booking, and the comments in it are very pertinent. Choosing restaurants with high scores will basically not trample on thunder. However, it is an all-Japanese interface, and it is more troublesome to use on the Android side.

I recently found a small program "Japan's most in-reservation", which can make reservations for restaurants in Tokyo, has a full Chinese interface, supports online payment, and has Chinese customer service. However, there are fewer shops at present, but the small program itself is quite reliable and worth recommending.
