Japan Flag: Meaning, Colors, History & Facts
Japan’s national flag is a white field with one deep-red sun disc in the centre. Its official name is Nisshōki, while it is commonly known as the Hinomaru.
What does Japan’s flag look like?
The design is exceptionally simple: a plain white rectangle with one deep-red circular disc exactly in the centre.
What is the flag called?
The official name is Nisshōki. It is much more commonly called Hinomaru, usually translated as “sun disc” or “circle of the sun.”
Why is there a red sun?
The sun has deep roots in Japanese cultural and political symbolism. Japan’s eastern geographic position and traditional association with the rising sun made the solar disc a natural national emblem.

What are the official proportions?
The Government of Japan specifies a 2:3 ratio. The deep-red disc is centred and has a diameter equal to three-fifths of the flag’s height.
What do white and red mean?
The 1999 law defines the colors and geometry but does not prescribe a detailed statutory symbolism for white and red. Popular cultural interpretations often connect white with purity and the red sun with vitality and national identity.
How old is the Hinomaru?
Sun-disc banners were used in Japan long before modern flag law. The Hinomaru became increasingly standardized as a national and maritime symbol during the nineteenth century and continued through the modern era.
When did it become the legal national flag?
The Law Regarding the National Flag and National Anthem formally established the Nisshōki as Japan’s national flag in 1999.

How can you identify Japan’s flag?
Japan’s national flag has no text, stripes or additional emblems: just one deep-red disc on a white field. The disc is perfectly centred, which helps distinguish it from flags where a sun or circle is offset.
Why is the design so effective?
The Hinomaru uses extreme visual simplicity. A single geometric symbol, strong color contrast and large areas of empty space make the flag recognizable even when reproduced very small or seen from far away.
