eSIM in Japan
Asia
Japan has wide eSIM support and dependable Wi-Fi — most travellers get by with a small data plan, but a local or travel eSIM is recommended for navigation and translation apps.
Free Wi-Fi is abundant in stations, convenience stores, and hotels — even a low-data eSIM plan covers most travellers comfortably.
