Tourist eSIM eSIM Data Plans for Japan

Tourist eSIM does not provide a truly unlimited data eSIM for Japan. Its plans labeled “Unlimited Data” actually give a fixed data allowance, such as the Japan • Unlimited Data • 1 Day plan, which provides 2GB of high‑speed data and reduces speed to 256kbps once the limit is reached, and the Japan • Unlimited Data • 20 Days plan, which allows 2GB per day before throttling to 256kbps. Because the data is capped, these plans may be less cost‑effective for heavy data users.

Fixed data plans are available as alternatives. For example, the 100 GB plan for 31 days in Japan gives a large, pre‑defined data supply without any speed reductions, while the 100 GB plan for 180 days across 17 Japanese‑covering countries offers 5G connectivity. Choosing a fixed data plan can be more economical unless a traveler needs extremely high data volumes in a very short time.

Tourist eSIM does not provide Japan eSIM packages that include a phone number or SMS capability. Those services are unavailable for Japan from this provider.

Tourist eSIM only offers data‑only eSIM plans for Japan. Travelers who need calling or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not require a local phone number or SMS support.

Tourist eSIM offers nine single‑country plans and 135 multi‑country plans for Japan. The plans include both fixed data amounts and daily data cap options, ranging from 1 GB to 100 GB in data, with prices spanning $2.32 to $455.36.
