Hungry eSIM eSIM Data Plans for Japan

Hungry eSIM does not provide a truly unlimited high‑speed data plan for Japan. All plans that carry the “Unlimited” label are in fact fixed‑data plans; after the allotted amount (from 500 MB to 10 GB) is consumed the connection speeds drop (for example, to 384 kbps). Travelers who need large amounts of data can instead choose from the fixed‑data offerings, such as the 30‑day 20 GB plan or the 30‑day 50 GB plan. These plans deliver full‑speed 5G data for the entire validity period, often making them a more cost‑effective option unless extremely heavy data usage is expected.

Hungry eSIM does not provide a Japan eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for Japan. Travelers who need voice or text can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but not all destinations allow unrestricted access to these services. It is recommended that travelers confirm whether the apps they depend on are accessible in Japan before making a purchase.

Hungry eSIM offers 13 single‑country plans and 51 multi‑country plans for Japan. Prices range from $2.09 to $179.36, with data caps from 500 MB to 50 GB and validity periods from 1 to 365 days. Some plans include reduced speed options.
