In Japan the standard voltage is 100 V with a frequency of 50 Hz in eastern Japan (including Tokyo). The power plugs are Type A and Type B, the same as those used in the United States. Travelers from countries using 220–240 V will need a voltage converter and possibly a plug adapter for their electrical appliances.

Travelers entering Japan may bring a limited quantity of medication for personal use. Prescription medicines are generally allowed for up to one month’s supply, while over-the-counter medications are typically limited to two months’ supply. Some medications that are legal in other countries may be restricted or prohibited in Japan, especially those containing stimulants, narcotics, or certain psychotropic substances. It is recommended to check Japanese regulations in advance and carry prescriptions or medical documentation when necessary.

Tokyo is served by two major international airports: Narita International Airport (IATA: NRT), located approximately 60 km (37 mi) east of central Tokyo, and Haneda Airport (Tokyo International Airport, IATA: HND), located about 15 km (9 mi) south of the city center. Haneda handles a large number of domestic flights as well as international routes, while Narita is a major hub for long-haul international travel.

Tokyo has one of the most extensive and efficient railway networks in the world. Tokyo Station is the city’s main rail hub, serving local, regional, and long-distance trains, including the Shinkansen (bullet trains) connecting Tokyo with major cities across Japan. Other major stations such as Shinjuku, Shibuya, and Ueno also function as key transportation hubs.

Tokyo’s public transport system includes trains, subways, buses, and monorails. The Tokyo Metro and Toei Subway operate numerous underground lines covering the entire city. Trains are punctual, frequent, and easy to use. Tickets and rechargeable IC cards (such as Suica and PASMO) can be used across most transport services. Public transport generally operates from early morning until around midnight, with limited late-night services.

• Licensed taxis

Bikes
Tokyo offers bicycle rental and bike-sharing services throughout the city. Public bike-sharing systems allow users to rent and return bicycles at designated stations, often located near train stations and popular areas. Registration is usually required via a mobile app or website, and payment is made by credit card or electronic payment systems. Cycling is a popular way to explore neighborhoods, though riders should follow local traffic rules and regulations.

Travelers from countries not covered by visa exemption agreements must obtain a visa prior to arrival. Passports must be valid for the duration of the stay. Visitors are not permitted to engage in paid work without the appropriate visa.
