The Japanese flag: meaning, history and design

The Japanese flag, called Nisshoki (sun-mark flag) and commonly known as Hinomaru (circle of the sun), is one of the simplest national flags in the world: a red disc centred on a white rectangle. Its design reflects Japan's name, Nihon or Nippon, often translated as the origin of the sun.

Meaning

The red disc represents the sun, linked to the sun goddess Amaterasu in Shinto tradition and to the idea of Japan as the land of the rising sun. White is often associated with purity and honesty. The design has been used on fans, banners and ships for centuries.

History

Sun-disc banners appear in Japanese history from at least the medieval period. In 1870, the Hinomaru was designated as the ensign for merchant ships. It served as the de facto national flag for more than a century before being formally confirmed by the Act on National Flag and Anthem in 1999.

The 1999 law slightly adjusted the earlier proportions, which had placed the disc a little off-centre and used a 7:10 ratio.

The Rising Sun flag

The Rising Sun flag (Kyokujitsu-ki), with red rays spreading from the disc, is a different flag. It is used today by the Japan Maritime Self-Defense Force and appears in some traditional designs, but it is associated with Japan's wartime past in neighbouring countries and remains controversial. The national flag is the plain disc.

When the flag is displayed

The flag flies on government buildings, at schools during ceremonies, at sports events and on national holidays, when some households and businesses also display it. Treating it with respect, as with any national flag, is expected.

The flag in everyday design

The simple red-and-white motif appears in packed lunches, such as the hinomaru bento with a pickled plum on white rice, and in countless logos and souvenirs. Recognising the Japanese flag helps decode many symbols seen during a trip.

Flag etiquette

The flag should not be allowed to touch the ground, and it is taken down at sunset when flown outdoors at official buildings. During mourning periods, it may be flown at half-mast or with a black ribbon.

Prefectural flags

Each of the 47 prefectures has its own flag, often a stylised symbol on a coloured background. Tokyo's flag features a six-pointed emblem on purple, while Hokkaido's shows a seven-pointed star.

The national anthem

The national anthem, Kimigayo, recognised by the same 1999 law as the flag, is one of the shortest anthems in the world. Its lyrics come from a classical poem over a thousand years old.

Colour and symbolism in design

Red and white together, called kohaku, are associated with celebration and good fortune in Japan. They appear in ceremonies, New Year decorations and the year-end singing contest broadcast on television, which reinforces the cheerful image of the national colours.
