Saharat Thai Doem was an administrative division of Thailand. It encompassed parts of the Shan States of British Burma annexed by the Thai government after the Japanese conquest of Burma.

The Japanese invasion of Burma was the opening phase of the Burma campaign in the South-East Asian theatre of World War II, which took place over four years from 1942 to 1945. During the first year of the campaign, the Japanese Army drove British Empire and Chinese forces out of Burma, then began the Japanese occupation of Burma and formed a nominally independent Burmese administrative government.
