Hiroshima 広島県
Origin
Both the emblem and flag were established by prefectural notice No. 572 of July 16, 1966. The katakana ヒ (hi), the first syllable of Hiroshima, is stylized into a circle expressing the harmony and unity of the prefecture's people, while the overlapping of the circles expresses the prefecture's advance and development.
