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 ( 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.
