Adoption of Japanese National Flag

Date: August 13, 1999 • Location: Tokyo, Japan

The Act on National Flag and Anthem , abbreviated as 国旗国歌法, is a law that formally established Japan's national flag and anthem. Before its ratification on August 13, 1999, there was no official flag or anthem for Japan. The nisshōki (日章旗) flag, commonly referred to as the hinomaru (日の丸), had represented Japan unofficially since 1870; "Kimigayo" (君が代) had been used as Japan's de facto anthem since 1880.
