KDDI and JR East expand free data access for Japan SIM users to 83 stations

KDDI and JR East are broadening the povo Data Oasis service for inbound travelers using Japan SIM, with free data top-ups available at 83 stations from June 9, 2026. The move ties mobile connectivity more closely to rail travel and airport access as Japan tourism demand continues to rebound.

Why it matters: - Japan SIM users can now get free mobile data at more stations, making it easier to stay connected during arrival, transit and sightseeing. - The expansion is aimed at international visitors who need quick access to maps, transit information and other travel tools. - The service is available mainly in JR East areas, including major Tokyo hubs and airport stations.

What happened: - KDDI Corporation and East Japan Railway Company said the number of stations eligible for povo Data Oasis will expand from June 9, 2026. - The service will cover a total of 83 stations. - Japan SIM users can receive the service at eligible stations by accessing a dedicated website from their smartphones. - Japan SIM can also be purchased through Welcome Suica Mobile, JR East’s app for international visitors.

The details: - povo Data Oasis gives Japan SIM users 0.5GB of free data per day at eligible stations. - The monthly cap is 5GB, or 10 uses in total. - The availability period runs from Dec. 11, 2025, with an end date still to be announced. - Eligible stations include Akihabara, Shinjuku, Shibuya, Tokyo, Ueno, Yokohama, Narita Airport terminals, Haneda Airport terminals, Sendai, Sapporo-area hubs are not included, and many other JR East stations across the Tokyo metropolitan area and beyond. - GALA Yuzawa Station is included, but only when Shinkansen service is operating there. - The service is available to customers using Japan SIM. - Japan SIM runs on the au network and offers 5G connectivity through povo2.0. - Japan SIM customers can choose from 10 topping plans, including fixed-data and unlimited-data options.

Between the lines: - KDDI and JR East are linking rail services and mobile connectivity to create a smoother travel experience for inbound visitors. - The station-based data top-up model encourages use at transit points where travelers are already stopping. - The Welcome Suica Mobile tie-in suggests JR East is trying to make digital onboarding easier before visitors even reach a ticket counter.
