Japan eSIM

Japan's mobile networks are dense and dependable almost everywhere a visitor goes, from the Shinkansen corridors between Tokyo and Osaka to the deep metro tunnels beneath both cities. The main exceptions are mountain valleys in Nagano and some of the smaller Setouchi islands, where signal can thin out between villages. Convenience-store logistics, restaurant queuing systems and train transfers all lean on a phone here, so a steady data connection matters more than in many destinations. Travellers doing multi-city rail trips tend to use data heavily for translation apps and station navigation, while those staying in one city, such as Kyoto, generally need far less.
