Tourist eSIM eSIM Data Plans for Japan

Tourist eSIM does not provide a truly unlimited data eSIM for Japan. The plans that carry “Unlimited” in their name give a fixed high‑speed data allowance that resets each day and then throttle the speed once the daily limit is reached. For example, the Japan • Unlimited Data • 1 Day plan offers 3GB of high‑speed data for one day and reduces speed to 256kbps after the allowance is used, while the Japan • Unlimited Data • 30 Days plan provides 3GB of high‑speed data per day for 30 days and throttles to 1000kbps after the daily limit. Travelers who need more data can choose fixed data plans such as the 100GB for 180 days plan, which offers a larger, non‑throttled data allowance over a longer period.

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.
