Additionally, TooSim has six multi-country plans that include Japan alongside other countries. These plans offer varying data amounts and validity periods depending on the selected package.
Does TooSim offer unlimited data eSIM for Japan?

Instead, the provider offers fixed‑data plans such as 20GB, 10GB, and 5GB for 30 days, all with tethering allowed. These options are priced between $12.99 and $26.99 USD and can be more cost‑effective for travelers who do not need unlimited data. If you anticipate a very heavy data usage, you may want to compare the higher‑capacity plans or consider a different service that offers an unlimited option.
