Questions about eSIMs in Japan

Answers come from the plans we checked and from what each provider states on its website.

Providers compared

For Japan, we compare plans from GigSky, GoMoWorld, Jetpac, Nomad, Orange Travel, PlanJapan, Ubigi, and Yesim. This comparison is not exhaustive: other providers exist, and we add more over time.

How our comparison works

What is the cheapest eSIM for Japan?

For one week with 6 GB, the cheapest plan in our comparison is GoMoWorld, at $12.99 (14 GB · 30 days). The cheapest of all the plans we found costs $2.99 at GigSky (1 GB · 7 days). Prices change often: the podium above is recalculated at every check.

Which eSIM for a month in Japan?

For 30 days of everyday use (24 GB), the cheapest is GoMoWorld at $24.99 (30 GB · 30 days). The best unlimited plan is PlanJapan, at $95.99 (Unlimited · 30 days): no daily cap announced.

Are unlimited plans really unlimited?

Rarely without conditions. At most of the providers we compare, the speed drops after a daily amount of data: 3.5 GB at GigSky, 3 GB at Jetpac, 2 GB at Nomad, and 5 GB at Ubigi. You stay connected at a slower speed, enough for messages and maps but not for video. The terms of each plan are shown on the podium.

What are the mobile networks in Japan?

Japan has four mobile operators: NTT Docomo, KDDI (au), SoftBank and Rakuten Mobile. A travel eSIM uses one or more of them. When the provider says which, the network appears under its name on the podium.

How much data do I need for a week in Japan?

Count about 0.2 GB a day for maps and messages, 0.6 GB more with social media, and 1.2 GB with video and video calls. For 7 days of maps and social media, 6 GB is enough. Beyond 25 GB, look at unlimited plans.

Is 5G available in Japan?

7 of the 8 providers advertise 5G in Japan: GigSky, GoMoWorld, Jetpac, Orange Travel, PlanJapan, Ubigi, and Yesim. It depends on local coverage; elsewhere you get 4G.

Can I use my eSIM as a hotspot in Japan?

Yes: 8 providers out of 8 allow it. Only PlanJapan states a limit: 10 GB a day (unlimited). The others do not state one.

When should I activate my eSIM for Japan?

With most of the providers we compare, validity starts when you first connect there, so you can install the eSIM before you leave. Time to activate after purchase: 1 year with GigSky, 60 days (unlimited) or 180 days (data) with PlanJapan, 6 months with Ubigi, 3 months with Jetpac, 90 days with Yesim, and 60 days with Nomad. With GoMoWorld, the plan starts when you launch it in the app.

Do I need ID for an eSIM in Japan?

Not with GigSky, Jetpac, Nomad, and Yesim: no identity check is required. With Orange Travel, an ID check (passport) is required after 31 days. The other providers do not say.
