eSIM Cards eSIM Data Plans for Japan

eSIM Cards does not provide an unlimited data eSIM option for Japan.

Instead, the provider offers fixed data plans that combine a specific data allowance with a set validity period. For example, the “Japan 300GB Travel Plan for 15 days” lets travelers use up to 300GB of high‑speed 5G data during a 15‑day window, while the “Global 100 GB for 5 days” and “Global 100 GB for 10 days” plans provide 100GB of 5G data for 5 or 10 days respectively. Additional smaller choices include a 50GB plan for 30 days and a 20GB plan for 30 days. These fixed bundles can be more cost‑effective for travelers who do not need an unlimited data allowance.

eSIM Cards does not provide a Japan eSIM that includes a phone number or SMS capability. The provider’s offerings for Japan are limited to data‑only plans.

Travelers can still use popular VoIP services such as WhatsApp, Telegram, and iMessage over the data connection, but those apps must be verified for availability in Japan before purchasing.

eSIM Cards offers 8 single‑country plans and 2 multi‑country plans for Japan, a total of 10 data packages. Prices run from about $3.93 to $69.09 USD, while data caps vary between 3 GB and 300 GB. Validity periods range from five to thirty days, and several plans include tethering permission.
