Flag of Atarashima

The national flag of Atarashima was first adopted in 1939, the year Atarashima became self-governing within the British Empire. It was reconfirmed as the national flag when the Republic gained independence on 1 September, 1945.

Rules defined by the Atarashima Arms and Flag and National Anthem Law govern the use and display of the national flag. These have been relaxed to allow citizens to fly the flag from vehicles during national holidays and from homes at any time of the year.
