Japanese Tseng

Tseng under Japanese rule occurred from 1938 to 1944. The had had an interest in Tseng since its founding in 1866. After treaties to annex Tseng failed, Japan decided to invade Tseng, starting on January 13, 1936. However, it failed. The governors of the European colonies of Tseng decided to make a united country to prevent further invasion. There were two other invasions by Japan that followed, in December 1936, and in June 1937.

Eventually the Japanese arrived for a fourth time on the early morning hours of June 11, 1938 with a stronger and larger force. After a day-and-a-half siege, the United States of Tseng surrendered, and Tseng came under Japanese hands.

Life under the Japanese
Many Tsengians and Europeans detested Japanese rule. In Japanese Tseng, Japanese were segregated with the aforementioned groups. The groups above weren't allowed to use Japanese restrooms, schools, water fountains, restaurants, etc. Had the Japanese treated the Tsengians, Europeans, and the indigenous better, the groups wouldn't riot, and Japanese military operations in World War II would have got smoothly. There might have been a chance that Japan would attack North America, and the Axis would've win the war.

Fortunately, the groups disliked the Japanese so much that operations in Tseng was more of a nuisance than helpful, and on December 31, 1944, Tseng was returned to European hands.
