"For the current Republic of Cadasa, see Cadasa"The Republic of Cadasa (Japanese: , Kadasa-kyōwakoku) was a client state of the during, from 1942 to 1945.

Background
In 1939, World War II broke out. As many Cadasans still held discontent over Cadasa's participation in the First World War, not many people supported Cadasan entry into WWII. President T. H. Koh echoed these sentiments, declaring that, as long as he was president, "Cadasa will never lose another man due to war". As a result, Cadasa was neutral for the first part of the war.

However, Koh made a mistake when he appointed James Teoh, a known Japanophile and war sympathizer, to the post of vice-president in 1941. On July 3, 1942, Koh died due to poisoning, and Teoh automatically became president.

The republic
On the same day, Teoh announced the Pact of Friendship (Pacat Persabalan, 友好協定 ) between the Empire of Japan and Cadasa, whose relations were previously neutral. During Koh's tenure, Cadasan-Japanese relations decreased due to Koh disagreeing with the "savagery of the Imperial Army", referencing the Nanking Massacre and Second Sino-Japanese War. With Teoh's accession to the presidency, relations improved significantly, and Cadasa also became part of the.

On July 5, the Cadasan People's Assembly was renamed People's Assembly, and the composition radically changed. Out of 160 members, almost half (70) of the members were of the Japanese-controlled Cadasan military.

On July 6, 1942, Teoh ended Cadasan neutrality and declared war on the United States, United Kingdom, Soviet Union, and China, officially entering the war.

In November 1943, Teoh and a delegate of Cadasans attended the in Tokyo. Teoh spoke at length about how, "in just one year, Japan has modernized and civilized our country, while 67 years of British rule has utterly destroyed the economy and people of southern Cadasa...". Meanwhile, many Cadasans were being mistreated by the Japanese soldiers.

At the start of 1945, American and Vizhutuan-led Allied forces embarked on the liberation of Cadasa in the Cadasa campaign. On August 1, 1945, Teoh resigned and was replaced by N. Vijay, who severed all ties with Imperial Japan.
