The full story

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

The flag of Okayama is a very dark purple, aubergine in colour, with a golden circle in the centre. The circle is the kanji oka (岡), the first part of the name of the prefecture, bent until it closes into a circle. Almost no standard in the world uses purple: Japanese prefectural flags do.

How it came about

The design was chosen by public competition in 1967, on the twentieth anniversary of the law that organised Japanese local autonomy. The winning entry was by Kaiyu Ban, a designer from the city of Okayama, and emblem and flag were approved on 22 November 1967 by prefectural notification number 883.

How it has changed

The flag has not changed since 1967. What did change was the earlier coat of arms: from 1919 Okayama used an oka in the shape of a bell, replaced already in 1956 by a staff badge. In the simplified version the emblem can be in white, and the name can be written below.

What it means

  • Golden oka

    closed into a circle, it represents the union of the inhabitants and the development and leap forward of the prefecture, according to the official reading.

  • Aubergine purple

    the notification fixes the nasu-kon, the almost black purple of the aubergine.

Fun facts

  1. The old emblem looked like a fainted pig

    Governor Miki Yukiharu, elected after the war, summed up the 1919 emblem by saying it looked like a fainted pig. The phrase spread and the bell-shaped design lost all support until the 1967 competition.

  2. A flag that is often printed wrong

    The prefecture itself warns that the flag of Okayama is often described by mistake with a navy blue or brown ground instead of the official aubergine purple.
