Great coverage in major Japanese cities!
I had really solid 5G coverage in Tokyo, Kyoto, and Osaka. Worked well in those deep train stations when you really needed it to find your way on Google maps. Some minor drops in some more rural areas and in far off mountain hikes to temples. But I assume everyone was in the same boat. I would highly recommend this e-sim and definitely use it again for my Samsung 23 phone.

Travel eSIM
Easy to buy and install an eSIM whilst on holiday, good range of products. The dashboard on the App worked well and just a few clicks to buy a new plan when first one expired
