Japanese occupation, 1942
After the Japanese invasion of Burma in 1941, Ba Maw, the head of the Sinyetha party became the head of a puppet government, while Aung San, who ruled the Society of the Thakins, was appointed chief of the “National” Burmese army. The provisional pro-Japan government in 1942 adopted the flag of the Synyethe - Wunthanu party as the unofficial national flag (yellow, a green stripe atop, charged with a red rising sun).
