Japan's individual tourist visa to go abroad needs to freeze 50,000 deposits, but the bank said that they have no right to freeze it for me and must show it to the law enforcement department.

You go to the bank with your certificate and say that you want to apply for a personal visa to travel abroad, so that the deposit he gave you can be fixed to the specified date. This is what we call freezing, not freezing in a strict sense, because there are objections, problems, and temporary lack of funds, and law enforcement departments need to provide materials to freeze.
