Tokyo Metropolis has two official emblems. One is called the crest or monshō, another is called the symbol. It also has two official flags featuring either emblem.

The Crest of Tokyo Metropolis (東京都紋章, Tōkyō-to Monshō^?) was adopted on November 2, 1943, under the Metropolitan Announcement No.464 (告示第464号^?). It is same as the Crest of the former Tokyo City, decided by the city council on December 1889. It is believed to be designed by Hiromoto Watanabe (渡辺洪基, Watanabe Hiromoto^?), an alderman of the city.

The crest shows the Sun with six rays, representing Tokyo as the center of Japan. As most other prefectural crests in Japan, its color is not designated. The crest looks like a kanji 京 (kyō) of 東京 (Tokyo), but the metropolitan announcement does not explain as such.

The Flag of Tokyo Metropolis (東京都旗, Tōkyō-to-ki^?) was adopted on October 1, 1964, under the Metropolitan Announcement No.1042 (告示第1042号^?). It features a white Metropolitan Crest on center. The background color is Edo purple (江戸紫, Edo murasaki^?), a traditional color which was popular in Edo.

Tokyo (東京, Tōkyō^?, "Eastern Capital") [toːkʲoː], English /ˈtoʊki.oʊ/; officially Tokyo Metropolis (東京都, Tōkyō-to^?), is one of the 47 prefectures of Japan. Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the largest metropolitan area of the world. It is the seat of the Japanese government and the Imperial Palace, and the home of the Japanese Imperial Family. Tokyo is in the Kantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. Tokyo Metropolis was formed in 1943 from the merger of the former Tokyo Prefecture (東京府, Tōkyō-fu^?) and the city of Tokyo (東京市, Tōkyō-shi^?).

The Tokyo Metropolitan government administers the 23 special wards of Tokyo (each governed as a city), which cover the area that was the city of Tokyo, as well as 39 municipalities in the western part of the prefecture and the two outlying island chains. The population of the special wards is over 8 million people, with the total population of the prefecture exceeding 13 million. The prefecture is part of the world's most populous metropolitan area with upwards of 35 million people and the world's largest urban agglomeration economy with a GDP of US$1.479 trillion at purchasing power parity in 2008, ahead of New York City metropolitan area, which ranks second on the list. The city hosts 47 of the Fortune Global 500 companies, the highest amount of any city.
