Tokyo Narita International Airport

Official Languages: Japanese

English support is commonly available in major tourist areas, airports, large hotels, and on main rail networks, but everyday spoken English can be limited, especially outside big cities. Translation apps are very useful.

Mobile Network: Mobile coverage is typically excellent in cities, on major train routes, and in most towns. Coverage can weaken in remote mountain areas, tunnels, and some rural coastal areas. 5G is available in major urban areas, with strong 4G nationwide.

Roaming/SIM/eSIM: Roaming is convenient for short stays but can be expensive unless your home plan includes Japan. A local SIM usually offers good value for longer trips if your phone is unlocked, but voice service options for short-term visitors may be limited. An eSIM is often the easiest choice for compatible phones because it can be installed before arrival and usually provides competitive data pricing. Pocket Wi-Fi can still work well for groups or travelers with several devices, but it adds another device to charge and carry.

Card acceptance is widespread in hotels, department stores, larger restaurants, and transport booking, but cash is still commonly needed at smaller eateries, local shops, temples, rural areas, and some ticket machines. IC cards and mobile wallet payments are common for transport and many convenience purchases.

Tipping is generally not expected in Japan and can be awkward in standard service situations. Good service is built into normal pricing. Some upscale hotels or restaurants may include a service charge, and there are occasional exceptions for private guides or special arrangements, but visitors typically do not need to tip.

Plug Type: Type A and Type B

Voltage: 100 V, 50 Hz in eastern Japan and 60 Hz in western Japan
