One Japan eSIM. From Nagoya to the bullet train and back.
Heading to the 2026 Asian Games in Aichi & Nagoya? One Japan eSIM keeps you connected from the venues to the Shinkansen and beyond.
The 19th Asian Games return to Japan in September 2026, hosted across Aichi Prefecture with Nagoya at its centre. With 46 nations, 461 events and over 15,000 athletes expected, it's the second-biggest multi-sport event on the planet - and a perfect excuse to combine sport with a Shinkansen-powered tour of Japan. Our JamboSim Japan eSIM runs on top-tier Japanese partner networks (NTT Docomo / SoftBank), giving you fast 5G/4G data the moment you land at Chubu Centrair or Narita. No fiddly SIM card vending machines at the airport, no roaming bills, and no awkward gaps when you board the bullet train to Tokyo or Kyoto. Activate it as soon as your flight lands, use it across all 47 prefectures, and top up if your trip stretches beyond the closing ceremony.
