Japan eSIM guide

Staying connected in Japan
Japan's mobile networks — NTT Docomo, KDDI (au), SoftBank and Rakuten Mobile — offer fast 4G and 5G coverage in cities and along major train lines, including much of the Shinkansen network and the Tokyo and Osaka subways.
Mobile data makes getting around Japan much easier: navigation apps handle complex train transfers, and camera translation apps help with menus and signs. Free public Wi-Fi exists in stations and some shops, but it often requires registration and can be unreliable, so many travelers prefer their own data connection.
