GIGAGO eSIM Data Plans for Japan

GIGAGO does not provide an unlimited data eSIM plan for Japan. The provider’s available options in this destination are fixed data plans. For example, a 50GB plan can be purchased for 5 days at $67.50 USD and a 20GB plan is available for 5 days at $27.50 USD. These examples illustrate the type of large‑data options on offer, but they are only a subset of the full selection. Choosing a fixed data plan may be more cost‑effective for most travelers, unless a user requires an extremely high volume of data that exceeds the limits of the available plans.

GIGAGO does not offer eSIM plans that include a phone number or SMS capability for travelers in Japan. The provider sells only data‑only eSIM packages that grant access to 4G/5G internet.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.

GIGAGO lists 28 single‑country data plans for Japan and 42 multi‑country plans that include Japan within a broader itinerary. Prices for these plans range from roughly $7.50 to $94.50 USD, and data caps span from 500 MB up to 50 GB over validity periods of 3 to 30 days. Some offerings are fixed‑data plans, providing a set amount of data for the entire validity, while others are daily‑cap plans that reset each day, allowing a maximum data usage per day. These options give travelers flexibility for both short visits and longer stays.
