Shonan (Japanese: 昭南, Hepburn: Shōnan; Kunrei-shiki: Syônan), officially Shonan 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, 6:20 PM local time, during World War II.
The Japanese military forces occupied Singapore after defeating the combined British, Indian, Australian, Malayan and the Straits Settlements garrison in the Battle of Singapore within seven days. The occupation became a major turning point in the histories of several nations, including those of Japan, Britain and Singapore. Singapore was renamed Shonan-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).
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.
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.
Events leading to the occupation
Malaya was hit by the first Japanese bombs on 8 December 1941. The Japanese forces initially focused on invading Malaya (present-day Peninsular Malaysia), which they captured within 55 days. They captured Johor Bahru by 31 January 1942, with the British forces retreating to Singapore and blowing up the Johor-Singapore Causeway, which linked Singapore to the mainland. Singapore was the foremost British military base and economic port in South–East Asia and had been of great importance to British interwar defence strategy. Singapore was considered so important that Prime Minister Winston Churchill ordered the British Lieutenant-General, Arthur Percival, to fight to the last man. Percival commanded 85,000 Allied troops at Singapore, although many units were under-strength and most units lacked experience. The British outnumbered the Japanese but much of the water for the island was drawn from reservoirs on the mainland.
The Battle of Singapore lasted from 8 to 15 February 1942. On 8 February, the Japanese crossed the Johore Strait by boat and attacked Singapore from the north-west, at the weakest point in the defences. Percival had expected a crossing in the north-east, especially following a Japanese feint at Pulau Ubin the day before, and failed to reinforce the defenders in time. Communication and leadership failures beset the Allies and there were few defensive positions or reserves near the beachhead. The Japanese advance continued and the Allies began to run out of supplies, particularly after the Battle of Bukit Timah from 10 to 12 February and the Battle of Pasir Panjang on 13 February. During the Alexandra Hospital massacre on 14 February, Japanese soldiers killed more than 200 hospital staff and patients. By 15 February, about a million civilians in the city were crammed into the remaining area held by Allied forces, 1 percent of the island. Japanese aircraft continuously bombed the civilian water supply which was expected to fail within days. The Japanese were also almost at the end of their supplies and Yamashita wanted to avoid costly house-to-house fighting.
Japanese General Tomoyuki Yamashita demanded unconditional surrender and on the afternoon of 15 February, Percival capitulated. About 80,000 British, Indian, Australian and local troops became prisoners of war, joining the 50,000 taken in Malaya; many died of neglect, abuse or forced labour. Three days after the British surrender, the Japanese began the Sook Ching purge, killing thousands of civilians. The Japanese held Singapore until the end of the war. Churchill called it the worst disaster in British military history.
Life during the occupation
Time of mass-terror
The main army which took Malaya, the 25th Army, was redeployed to other fronts such as the Philippines and New Guinea shortly after the fall of Singapore. The Kempeitai (the Japanese military police), which was the dominant occupation unit in Singapore, committed numerous atrocities towards the common people. They introduced the system of "Sook Ching", meaning "purging through purification" in Chinese, to get rid of those, especially ethnic Chinese, deemed to be hostile to the Empire of Japan (anti-Japanese elements in the local population). The Sook Ching massacres claimed the lives of between 25,000 and 55,000 ethnic Chinese in Singapore as well as in neighboring Malaya. These victims, mainly males between the ages of 18 and 50, were rounded up and taken to deserted spots and remote locations around the island, such as Changi Beach, Punggol Point, and Siglap, and killed systematically using machine guns and rifles.
Moreover, the Kempeitai established an island-wide network of local informants to help them identify those they suspected as anti-Japanese. These informers were well-paid by the Kempeitai and had no fear of being arrested for their loyalty was not in question to the occupation forces. These informers worked at Kempeitai screening centres where the Japanese attempted to single out anti-Japanese elements for execution. Japanese soldiers and Kempeitai officers patrolled the streets often and all commoners had to bow to them with respect when they passed by. Those who failed to do so would be slapped, punched, beaten and some people would even be taken away to imprisonment or even face execution.
Other changes to life in Singapore
To discourage Western influence, which Japan sought to eliminate from the very start of their invasion, the Japanese set up schools and education institutions and pressured the local people to learn Japanese. Textbooks and language guidebooks were printed in Japanese and radios and movies were broadcast and screened in Japanese. Every morning, school-children had to stand facing the direction of Japan (in the case of Singapore, looking northeast) and sing the Japanese national anthem ("Kimigayo"). Japanese propaganda banners and posters also went up all around Singapore, as did many Japanese Rising Sun flags raised and hung across many major buildings.
Scarcity of basic needs
Basic resources, ranging from food to medication, were scarce during the occupation. The prices of basic necessities increased drastically over the three and a half years due to hyperinflation. For example, the price of rice increased from $5 per 100 catties (about 60 kg or 130 lb) to $5,000 by the end of the occupation between August and September 1945. The Japanese issued ration cards, also known as "Peace Living Certificates", which were very precious to the people at that time, to limit the amount of resources distributed to the civilian population. Adults could purchase 5 kg (11 lb) of rice per month and children received 2 kg (4.4 lb) accordingly. The amount of rice for adults was reduced by 25% as the war progressed, as much of the scarce rice supplies were sent to feed the Japanese military.
The Japanese issued "Banana Money" (so referred to due to the image of a banana tree printed on most of such notes of the currency) as their main currency during the occupation period since British Straits currency became rarer and was subsequently phased out when the Japanese took over in 1942. They instituted elements of a command economy in which there were restrictions on the demand and supply of resources, thus creating a popular black market from which the locals could obtain key scarce resources such as rice, meat, and medicine. The "Banana" currency started to suffer from high inflation and dropped drastically in value because the occupation authorities would simply print more whenever they needed it; consequently on the black market, Straits currency was more widely used.
Food availability and quality decreased greatly. Sweet potatoes, tapiocas and yams became the staple food of most diets of many Singaporeans because they were considerably cheaper than rice and could also be grown fast and easily in backyard gardens. They were then turned into a variety of dishes, as both desserts and all three meals of the day. Such foods helped to fend starvation off, with limited success in terms of nutrients gained, and new ways of consuming sweet potatoes, tapiocas and yams with other products were regularly invented and created to help stave off the monotony. Both the British colonial and Japanese occupation authorities encouraged their local population to grow their own food even if they had the smallest amount of land. The encouragement and production were similar to what occurred with "Victory Gardens" in Western nations (predominantly in Europe) during World War II as food supplies grew ever scarcer. Ipomoea aquatica, which grew relatively easily and flourished relatively well near water sources, also became a popular food-crop.
Education
After taking Singapore, the Japanese established the Shonan Japanese School (昭南日本学園, Shōnan Nihon Gakuen), to educate the Malays, Chinese, Indians, and Eurasians in the Japanese language. Faye Yuan Kleeman, the author of Under an Imperial Sun: Japanese Colonial Literature of Taiwan and the South wrote that it was the most successful of such schools in Southeast Asia. During the occupation, the Japanese had also opened the Shonan First People's School.
Allied attacks
Singapore was the target of various operations masterminded by Allied forces to disrupt Japanese military activities. On 26 September 1943, an Allied commando unit known as Z Force led by Major Ivan Lyon infiltrated Singapore Harbour and sank or damaged seven Japanese ships comprising over 39,000 long tons (40,000 metric tons). Lyon led another operation, codenamed "Rimau", with the same objective almost a year later and sank three ships. Lyon and 13 of his men were killed fighting the Japanese during this operation. The other 10 men who participated in the operation were captured, charged with espionage in a kangaroo court and subsequently executed.
Lim Bo Seng of Force 136 led another operation, code-named Gustavus, he recruited and trained hundreds of secret agents through intensive military intelligence missions from China and India. He set up the Sino-British guerrilla task force Force 136 in 1942 with Captain John Davis of the Special Operations Executive (SOE). Operation Gustavus was aimed at establishing an espionage network in Malaya and Singapore to gather intelligence about Japanese activities, and thereby aid the British in Operation Zipper – the code name for their plan to take back Singapore from the Japanese. Force 136 was eventually disbanded after the war.
In August 1945, two XE class midget submarines of the Royal Navy took part in Operation Struggle, a plan to infiltrate Singapore Harbour and sabotage the Japanese cruisers Takao and Myōkō using limpet mines. They inflicted heavy damage on Takao, earning Lieutenant Ian Edward Fraser the Victoria Cross. From November 1944 to May 1945, Singapore was subjected to air raids by British and American long-range bomber units.
Naval facilities and docks in Singapore were also bombed on eleven occasions by American air units between November 1944 and May 1945. These attacks caused some damage to their targets but also killed a number of civilians. Most Singaporeans, however, welcomed the raids as they were seen as heralding Singapore's liberation from Japanese rule.
End of the occupation
On 6 August 1945, the United States detonated an atomic bomb over the Japanese city of Hiroshima. Sixteen hours later, US President Harry S. Truman called again for Japan's surrender and warned it to "expect a rain of ruin from the air, the like of which has never been seen on this earth." On 8 August 1945, the Soviet Union declared war on Japan and the next day invaded the Japanese puppet state of Manchukuo. Later that day, the United States dropped a second atomic bomb, this time on the Japanese city of Nagasaki. Following those events, Emperor Hirohito intervened and ordered the Supreme Council for the Direction of the War to accept the terms the Allies had set down in the Potsdam Declaration to end the war. After several more days of behind-the-scenes negotiations and a failed coup d'état, Emperor Hirohito gave a recorded radio address across the Empire on 15 August. In the radio address, he announced the surrender of Japan to the Allies.
The surrender ceremony was held on 2 September aboard the United States Navy battleship USS Missouri at which officials from the Japanese government signed the Japanese Instrument of Surrender, thereby ending the hostilities.
