TravelKon eSIM Data Plans for Japan

TravelKon offers unlimited data eSIM plans for Japan. The plans use KDDI’s 5G network and range in validity from 3 days to 31 days, with standard pricing from $13.14 USD for the shortest option up to $82.30 USD for the longest period. Each plan is labeled as “Japan eSIM Unlimited Data” and allows tethering, although the advertised speed may be reduced after heavy use.

Because the plans are subject to a fair‑usage policy, speeds can be throttled if data consumption is high. For the most up‑to‑date information on typical speed limits at normal usage levels and the amount of data available before throttling, users should contact TravelKon directly.

TravelKon does offer eSIM plans for Japan that include a phone number and SMS capabilities. The available options provide 20GB, 50GB, or 100GB of high‑speed data for a validity of 30 days, with prices ranging from $40.80 USD to $100.28 USD.

Each of these plans includes a phone number with the dialing code +33, voice calling inbound and outbound, and SMS inbound and outbound. The number is not a local Japanese number but comes from France. Travelers should confirm the specific services they require directly with TravelKon, as the listed features apply to the three Japanese plans listed above.

TravelKon provides 34 single‑country data plans that specifically cover Japan and 26 multi‑country plans that include Japan among their destinations. These plans span a price range of approximately $2.77 to $172.21 and offer data caps from 1 GB up to unlimited, giving customers flexibility to choose a plan that fits their usage pattern and budget. The catalog includes both fixed‑data‑cap options, where a set amount of traffic is available for the entire validity period, and daily‑data‑cap options, where traffic is allocated on a per‑day basis.
