Roamify eSIM Data Plans for Japan

Roamify does provide unlimited data eSIM plans for Japan. The available options cover validity periods from 1 day up to 30 days, with prices ranging from $5.00 USD for a 1‑day plan to $79.90 USD for a 30‑day plan. All of these plans allow tethering and are marketed as unlimited, but the data is subject to a fair‑usage policy; speeds may be throttled after heavy use. Travelers who are concerned about potential speed reductions should contact Roamify directly to confirm whether a fair‑usage policy applies to their chosen plan and to learn the typical amount of data that can be used at normal speed.

Roamify offers several eSIM plans for Japan that include a phone number and support for inbound and outbound SMS. The plans range from 1 GB for 7 days up to 20 GB for 365 days, with prices from $15.00 USD to $105.00 USD. The phone numbers provided by Roamify carry a dialing code of +1 (for the majority of plans) and +33 (for the Asia Sprint 20 GB plan); these are not local Japanese numbers. All plans allow both incoming and outgoing voice calls and allow sending and receiving SMS. Travelers who need specific call or text capabilities should verify the details directly with Roamify.
