The flag of Hiroshima Prefecture (Japanese: 広島県旗, Hepburn: Hiroshima-ken ki) is a crimson field charged in the center with a white, stylized representation of the initial mora hi () in katakana.[1] On its own, the charge is the emblem of Hiroshima Prefecture (広島県章, Hiroshima-ken shō) and shares the same crimson color as the field of the flag. The overlapping circles of the emblem represent "the growing progress and development" of Hiroshima Prefecture.[1]
