Travelers heading to Osaka can now stay connected more easily and affordably than ever before. The Osaka Convention & Tourism Bureau, in collaboration with KDDI Corporation, has announced major updates to its “Osaka eSIM” service starting June 25, 2025. These updates include the launch of two new data packages designed specifically for long-term visitors: a 30 GB plan valid for 30 days and a 15 GB plan valid for 15 days. These additions expand the flexibility and appeal of the Osaka eSIM, which is already popular among international tourists for its convenience, fast setup, and access to KDDI’s high-quality au network.

The Osaka eSIM allows foreign visitors to Japan to skip the hassle of buying and swapping physical SIM cards. Instead, users can activate their plan within minutes using their smartphones, customizing their connectivity through a variety of “toppings”—data ”add-ons tailored to different lengths of stay and data needs. From quick 2-hour access for light users to new options for heavier data consumption, the Osaka eSIM now caters to a wider range of travel styles, including digital nomads, business travelers, and extended-stay tourists.

To celebrate the continued growth of this service, new users can also take advantage of a limited-time welcome offer: one full day of unlimited data free with a special promo code. With seamless activation, competitive pricing, and flexible plans, the Osaka eSIM continues to be one of the most traveler-friendly connectivity solutions in Japan.

Final thoughts about Osaka eSIM

As eSIM technology becomes an essential part of modern travel, we’re now seeing a rapid expansion of city-specific eSIM solutions—tailored not just by country, but by destination. In recent months, providers have launched dedicated eSIM offers for key cities like Seoul, Paris, and now Osaka, meeting travelers where they are with local, affordable, high-speed data plans. These announcements are becoming almost daily occurrences, and Osaka’s latest move is a clear reflection of this accelerating trend.

The timing couldn’t be more appropriate. With the Osaka Expo 2025 officially underway from April 13 to October 13, the city is experiencing a major surge in international tourism. The addition of new 15 GB and 30 GB long-stay eSIM plans is a strategic response to this influx—offering visitors greater flexibility and cost control, whether they’re attending the Expo or exploring the Kansai region.

For global travelers and digital nomads alike, the Osaka eSIM stands out as a scalable, traveler-friendly connectivity option. And for the industry, it marks another step in the localization of eSIM—one city at a time.
