From March 1, some big shopping malls in Japan have started to use UnionPay cards in China. I live in Tokyo. For example: Ginza, Akihabara and other places. There is no problem at all. Besides, I worked as an interpreter for tourists from China in a shopping mall the other day. Japanese service industry attaches great importance to China tourists at present. I think this is a good opportunity to make money. Hire people like us who know both Chinese and Japanese. Welcome to Tokyo for sightseeing.
