Tourist eSIM eSIM Data Plans for Japan

Tourist eSIM does not provide a truly unlimited high‑speed data plan for Japan. The plans labeled “Unlimited” give a daily high‑speed allowance— for example, Japan • Unlimited Data • 7 Days supplies 3 GB of 5G data per day for seven days, after which the speed falls to 1000 kbps. Travelers who need more data can choose a fixed‑bundle plan, such as 100 GB for 180 days, which allows continual high‑speed data until the 100 GB cap is reached and then reduces speed. Fixed data plans can be more cost‑effective unless a traveler expects to use data well beyond the stated allowances.

Tourist eSIM does not provide an eSIM that includes a phone number or SMS for Japan. The available plans are data‑only, so travelers cannot receive or make calls via the network or send standard SMS messages. However, they can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages. It is wise to verify whether these apps are accessible in Japan before purchasing, as some destinations may block or restrict specific services.

Tourist eSIM offers a total of 185 plans that include coverage for Japan. Of these, 24 are single‑country plans focused solely on Japan, while 161 are multi‑country plans that encompass Japan along with other destinations. The plans feature data caps ranging from 1 GB to 100 GB and prices that fall between $2.05 and $426.78. They include both fixed‑data options—151 plans that provide a set amount of data for the entire validity period—and daily‑cap options—34 plans that limit the data usage on a daily basis, giving travelers flexibility depending on how they intend to use their data.
