Syonan (Japanese: 昭南, Hepburn: Shōnan, Kunrei-shiki: Syônan), officially Syonan Island (Japanese: 昭南島, Hepburn: Shōnan-tō, Kunrei-shiki: Syônan-tô), was the name for Singapore when it was occupied and ruled by the Empire of Japan, following the fall and surrender of British military forces on 15 February 1942 during World War II.

Japanese military forces occupied it after defeating the combined British, Indian, Australian, Malayan and the Straits Settlements garrison in the Battle of Singapore. The occupation was to become a major turning point in the histories of several nations, including those of Japan, Britain, and Singapore. Singapore was renamed Syonan-to, meaning "Light of the South Island" and was also included as part of the Greater East Asia Co-Prosperity Sphere (Japanese: 大東亜共栄圏, Hepburn: Dai Tōa Kyōeiken).^[5][6]

Singapore was officially returned to British colonial rule on 12 September 1945, following the formal signing of the surrender at the Municipal Building, currently known as City Hall. After the return of the British, there was growing political sentiments amongst the local populace in tandem with the rise of anti-colonial and nationalist fervor, as many felt that the British were no longer competent with the administration and defence of the crown colony and its inhabitants.^[7]

Shortly after the war, the Straits Settlements was dissolved and Singapore became a separate crown colony in 1946. It would go on to achieve self-governance in 1959 and join with Malaya to form Malaysia in 1963, before becoming a sovereign city-state a few years later in 1965. The day of the surrender of the British to the Japanese in 1942 continues to be commemorated in Singapore with Total Defence Day, which is marked annually on 15 February.
