Tokyo is the capital city of Japan and it is the world's most populous metropolis with its stunning, stimulating and seductive atmosphere. It is one of Japan's 47 prefectures, consisting of 23 central city wards and multiple cities, towns and villages west of the city centre. Before 1868, Tokyo earlier known as Edo, was a small castle town in the 16th century. It became Japan's political centre in 1603 under Tokugawa Ieyasu then, after Emperor Meiji moved his seat to the city from the old capital of Kyoto in 1868, it became the official capital. The city's history can be appreciated in regions like Asakusa, and in many brilliant museums, historic temples and gardens.

Today, it offers a curious choice of shopping, entertainment, museums, galleries, shrines and temples for its visitors. Swaggering a stridency of contrasts, Japan’s megalopolis is by turns electrifying, enthralling and exhausting. It is a city of a dozen different characters; therefore visitors can pretty much choose their Tokyo based on whether they want frenzied and ear-splitting or serene zen-like calm; spiralling skyscrapers or tiny veiled backstreet reliquaries; the elastic and neon of the love inns or the tatami mat simplicity of traditional Ryokans. Tokyo offers an implausible volume to take in with its barrage of sights and sensations. It also offers a number of attractive green spaces in the city centre and within relatively short train rides at its suburbs.

Tokyo has the leading metropolitan economy in the world and is a major international finance center . It houses the headquarters of several of the world's largest investment banks and insurance companies, and serves as a hub for Japan's transportation, publishing, electronics and broadcasting industries.  Public transportation within Tokyo is ruled by an widespread network of clean and efficient trains and subways run by a variety of operators, with buses, monorails and trams playing a secondary feeder role.
