Japan Travel Essentials
Language: 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.
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.
Plug type: Type A and Type B
Voltage: 100 V, 50 Hz in eastern Japan and 60 Hz in western Japan
Adapter: Visitors from countries using different plug types will need an adapter. Many devices handle 100 to 240 V automatically, but check chargers carefully because Japan uses 100 V.
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.
Japan Safety, Culture & Tipping
Japan is generally very safe for visitors, with low violent crime rates and reliable infrastructure. Common travel issues are more often related to lost items, natural hazards such as earthquakes, typhoons, heavy rain, heat, or transport disruptions rather than street crime.
- Keep your passport secure and carry it, as foreign visitors may be required to show identification.
- Use official taxi ranks or licensed ride services where available.
- Prepare for earthquakes and severe weather by checking local alerts and hotel guidance.
- In summer, take heat and humidity seriously; carry water and use cooling measures.
- Late night rail services are limited compared with daytime frequency, so check last train times.
Do
- Stand to one side on escalators where local practice indicates, but follow station signs because customs vary by city.
- Be punctual for tours, trains, and restaurant reservations.
- Use the provided tray when paying at shops and restaurants if one is present.
- Learn a few simple phrases such as hello, thank you, and excuse me.
Avoid
- Do not eat or drink while walking in crowded areas where it is discouraged.
- Do not tip casually in ordinary situations, as it can cause confusion.
- Do not enter bathwater before washing at an onsen or sento.
- Do not talk loudly on public transport or play audio without headphones.
Local cultural tips
- • Queue neatly and wait your turn on platforms, escalators, and in shops.
- • Keep voices low on trains and avoid phone calls in train carriages.
- • Remove shoes when required in homes, some traditional accommodation, temples, fitting areas, and certain restaurants.
- • Carry a small bag for trash, as public bins can be limited.
- Bow lightly in greeting if appropriate, though a polite verbal greeting is enough for most visitors.
- Handle chopsticks respectfully; do not stick them upright in rice or pass food chopstick to chopstick.
- Keep cash, cards, and receipts organized because payment flow is often orderly and quick.
- Follow posted rules carefully in trains, shrines, museums, and accommodation.
- Be considerate of shared spaces and keep bags compact during busy commuting hours.
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.
