Airhub eSIM Data Plans for Japan

Airhub does not provide a truly unlimited data eSIM for Japan. The plan titled “Japan Unlimited data” gives 10GB of high‑speed data each day; after that limit the speed drops to 2000kbps until the next daily reset. For travelers who need more data, Airhub offers fixed‑data plans such as 100GB for 30 days and 300GB for 10 days, all available on 5G networks in Japan.

Airhub sells Japan eSIM plans that include a phone number and voice calling capability. The plans are valid for 30 days and range in price from $32.00 to $72.99 USD, with data caps from 20 GB to 100 GB. The phone numbers use the dialing code +33, which is not a local Japanese number, and the plans allow both inbound and outbound calls. However, the plans do not provide SMS functionality. Users who need SMS should confirm the details directly with Airhub.

Airhub provides 13 single‑country data plans and 27 multi‑country plans that include Japan. The available plans range in price from about $1.49 to $72.99 and in data allowance from 1 GB up to 300 GB, with validity periods spanning 1 to 90 days. The single‑country options give travelers a fixed data amount for use only in Japan, while the multi‑country plans allow the same data to be used across several destinations, offering flexibility for itineraries that include Japan and other countries.
