Good
Was very happy with service. 5G phone connected at 5G. One of the few options in Japan that will do that. Most roaming services won't and a lot of other prepaid providers won't.
Worst service ever, they send incomplete orders, no support, not recommended at all
Service was 4G rather than 5G but speeds were perfectly fine, even for real-time navigation. The few low numbers recorded in speed tests were almost all at Narita Airport.
10 GB each turned out to be plenty for 9 days in Tokyo. We did connect our phones to the hotel's WiFi but probably didn't need to.
Bought the 30 day 20gb Japan eSIM and it worked perfectly.
