現金を入金するにはどうすればよいですか

Haw can I deposit cash

Hello, if you mean that you would like to deposit with us, we are not a casino, so you can neither deposit nor withdraw money with us. 

However, if you want to deposit in a casino, you will have to register there and there will be a deposit button somewhere. Of course, if you have any problems or questions, I would direct them to live chat or support, who should be able to help you. 🙂
