Giga.Tel eSIM Data Plans for Japan

Giga.Tel provides 23 single‑country plans that cover Japan, and an additional 28 multi‑country plans that include Japan. The single‑country portfolio contains both fixed data‑cap options—ranging from 1 GB to 90 GB—and daily‑cap plans that allow a set amount of data per day, giving travelers flexibility depending on their usage style. Prices for Japan‑specific plans run from roughly $4.49 to $307.99, and validity can be as short as one day or extend up to a full year (365 days). All plans offer at least one type of data cap, with some also allowing tethering to other devices.

Giga.Tel does not provide a truly unlimited data eSIM for Japan. The plans titled “Global Unlimited” actually offer fixed data allowances of 10GB for 5 days, 14GB for 7 days, 20GB for 10 days, and 30GB for 15 days; after the cap is reached the connection speed is throttled, though the exact reduced speed is not specified in the available information.

Instead, Giga.Tel supplies a range of fixed data plans that may be more economical for most travelers. For example, a 90GB plan is valid for 365 days, a 60GB plan is also available for 365 days, and a 50GB plan is offered for 30 days. These options, together with the tethering‑enabled 60GB plan valid for 90 days, allow users to select a data amount that matches their usage needs. The fixed‑data approach can be more cost‑effective unless the traveler is an exceptionally heavy data consumer.
