The Flag of Osaka Prefecture, Japan, is a rectangular banner with distinctive symbolism. It consists of three horizontal stripes in the proportions 2:3:2. The top and bottom stripes are white, while the middle one is deep purple (symbolizing the Taira clan). This flag design was adopted in 1964 as a representation of Osaka Prefecture’s history, with its colors reflecting the city’s connection to two significant samurai clans: the Minamoto and the Taira. The flag serves as a symbol of pride and identity for residents and visitors alike within the prefecture.
