For those visiting Japan, I'd like to add one important point. It's true that parts of Japan's judicial system are truly "middle age". https://www.huffpost.com/entry/hideaki-ueda-japan-shut-up-vi...

However, fortunately (or perhaps unfortunately), you can't bribe officials. Japan is a society where it's difficult to get special treatment by giving money, not just to officials. If you try to use bribes, you'll only be looked down upon and put in a worse position.
