CocoRoam eSIM Data Plans for Japan

CocoRoam does not provide an unlimited data eSIM plan for Japan. Travelers looking for high‑volume data can instead select from the provider’s fixed data offers. For example, the Asia 100GB 30d plan gives 100GB of data for 30 days and costs $110.00 USD, while the Asia 100GB 180d plan delivers the same data amount for 180 days at $133.50 USD.

Smaller, country‑specific options are also available, such as the Japan 50GB plans that run for 3, 5, or 7 days at prices ranging from $23 to $26 USD. Choosing a fixed data plan can be more cost‑effective unless a traveller is an extremely heavy data consumer and would prefer an unlimited option.

CocoRoam does not offer a Japan eSIM that includes a phone number or SMS capability. The provider only supplies data‑only plans for travelers. To make voice and text calls while in Japan, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

CocoRoam provides 86 single‑country plans that are dedicated to Japan alone and an additional 47 multi‑country plans that include Japan among their destinations, for a total of 133 plans that can be activated in Japan. The price range for these plans spans from $1.50 to $133.50, the data cap varies between 1 GB and 100 GB, and validity periods range from 1 day to 180 days. Some plans are fixed‑data bundles, allowing a set amount of data regardless of usage, while others offer a daily data cap that limits the amount of data you can use each day.
