Note that the visit of several places inside the Imperial Palace requires your advanced application. The application is available through a Web form in the Imperial Household Agency.

Akihabara: Akihabara is known as an Electric Town and the center of the Otaku culture; Otaku means people with obsessive interests, particularly anime, manga, or video games.

Ueno Area: Ueno Park, adjacent to the Ueno Station, is a large public park. Ueno Park is home to museums (e.g., Tokyo National Museum, The National Science Museum, and The National Museum of Western Art), Ueno Zoo, temples and shrines (e.g., Kaneiji Temple, and Tosho-gu Shrine), and Shinobazu Pond.
Ueno AMEYOKO (AMEYA-YOKOCHO), an Asian-fashioned market and shopping street, is also next to the Ueno Station.

Asakusa: Asakusa is most famous for the Senso-ji, a Buddhist temple and Kaminari-mon, its outer gate. Nakamise, a shopping arcade inside in Senso-ji Temple, is one of the best places in Tokyo to buy souvenirs.

Shinjuku: Shinjuku is a major commercial and administrative center. The view of Tokyo from the Tokyo metropolitan office in Shinjuku is wonderful.

A national garden, Shinjuku Gyoen, is another place to visit in Shinjuku area, which has a different mood from the center of Shinjuku as a business center.
