I used a Mobal eSIM https://www.mobal.com/japan-esims/ on my trip to Japan. Connecting took just a few minutes, and the internet worked without a hitch upon arrival. I’ve had no connection issues in two weeks. I used the service for navigation, bookings, and messaging. It’s convenient that you don’t have to look for a SIM card at the airport and waste time setting it up. The solution has been completely worth it.
