The SIM Shop eSIM Data Plans for Japan

Yes, The SIM Shop sells unlimited data eSIMs for Japan. The unlimited plans are available for 3, 5, 7 or 10 days, with prices ranging from $9.25 USD for the 3‑day option to $27.10 USD for the 10‑day option. These plans allow continuous data use at a maximum speed of 10Mbps (10 000 kbps) and include a hotspot allowance that increases with the plan length. While the provider notes that there is no total data cap or routine usage‑based reduction, speeds may be reduced during periods of heavy usage per the Fair Usage Policy, and exceptional network‑integrity measures can apply in emergencies or when the network is abused. Travelers who are concerned about speed throttling should contact The SIM Shop to confirm the typical data available at normal speed under the FUP.

The SIM Shop does not provide a Japan eSIM that includes a local phone number or SMS capabilities; only data‑only plans are available. Travelers who need voice or messaging can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these services, so users should verify access in Japan before purchasing.

The SIM Shop offers 23 single‑country data plans and 55 multi‑country plans for Japan. Prices range from about $3.54 to $132.81, while data caps span from 1 GB up to unlimited. The catalog includes both fixed‑data‑cap plans, where a set amount of data is available for the entire validity period, and daily‑data‑cap plans, which provide a daily allowance that can be used flexibly over the plan’s duration.
