When you are going to Japan, the first thing you start thinking about is not only the routes, but also how to stay in touch. I spent a long time choosing and finally decided to try Mobal eSIM https://www.mobal.com/japa... . I installed it in a couple of minutes, everything worked perfectly. The Internet is stable, even on trains between cities. I did not have to buy a SIM card at the airport or look for Wi-Fi. I think this is a convenient and modern solution for tourists. I can say that I was satisfied.
