In Japan, Airalo publishes SoftBank and KDDI as partner networks. 5G is announced. Hotspot sharing is not mentioned.
Airalo offers both fixed-volume and unlimited plans for Japan, so it can fit a light user as well as a heavy one. Compare the price per GB of the fixed plans with the unlimited ones for your trip length.
Plans are managed in the Airalo app. You can top up the same eSIM instead of buying a new one. Plans are data only, without a Japanese phone number.
Our score for Airalo is computed, not given: price for the need of each page, Japanese network, hotspot and options. That is why Airalo can rank differently on a 3-day page and on a 30-day one. The duels linked below compare it one to one with each alternative.

Turn on data roaming for the eSIM line, then check that the phone shows a Japanese network.
Your phone must be carrier-unlocked and eSIM-compatible. Check this in your phone settings before you buy.
