What should I do if my trip to Japan is pitted?

You can only admit it if you are cheated. Pay attention next time. You can post it in Weibo and post it for exposure to remind everyone not to be cheated! If you don't admit it, the process is very troublesome. If you say that you have been pitted to tens of thousands, call the police! If it is one or two thousand dollars, it is unnecessary! I earned it after working overtime for a while. 3000 to 10000, depending on your economic conditions, you can choose to call the police or not! But the Japanese police may not be on your side! If you want to get back at them, you'd better not, because you don't know what the Japanese law is like.
