The Symbol of Tokyo Metropolis was adopted on June 1, 1989, under the Metropolitan Announcement No.577 (Metropolitan Announcement No.577).

The design was selected by the Tokyo Metropolitan Symbol Selection Committee (Tokyo Metropolitan Symbol Selection Committee) from 20 candidates. The winning design was created by Rei Yoshimura (Rei Yoshimura), a professional graphic designer.

The vivid green symbol features the letter T for Tokyo. It shows dynamism, prosperity, affluency, and relaxation of the metropolis for future. The symbol looks like a leaf of gingko, the metropolitan tree. However, neither the metropolitan announcement nor the Japanese official website explain as such.
