The full story

How it was born, how it has changed and what it means.

Hiroshima is known worldwide for being the first city to be struck by an atomic bomb, in 1945. But its flag is not about that: it was born more than twenty years later and shows, in white on a deep maroon, the syllable hi (ヒ) of the katakana syllabary, the first one of the name of the prefecture.

How it came about

The prefecture approved the emblem in July 1966 and two years later, on 16 July 1968, notification number 572 regulated the flag that carries it. In the full fever of symbols of 1968, Hiroshima chose a design of modern lines, with no coats of arms from the past.

How it has changed

The flag has not changed since it was established.

What it means

  • White hi

    the initial syllable of Hiroshima, turned into two round curves.

  • Roundness

    according to the prefecture’s official interpretation, the curves symbolise the harmony and unity of the inhabitants, and their overlap, the progress and vigorous development of Hiroshima.

  • Maroon ground

    the rule fixes the shade with the Munsell colour chart 4R 4/11, a very dark red usually called wine colour.

Fun facts

  1. Calculated like the national flag

    On the flag of Hiroshima the emblem measures 3/5 of the height of the field, the same calculation as the red disc of the national flag of Japan. The prefectural order of 1968 specifies it that way.

  2. No relation to the bombing

    The emblem was created in 1966 and the flag in 1968, twenty-one years after the atomic attack, and its official meaning is citizen unity: it does not represent peace or mourning. There is no prefectural flag of peace.
