}} The {{Nihongo|31st Division|第31師団|Dai-sanjūichi Shidan}} was an infantry division of the Imperial Japanese Army. Its call sign was the {{Nihongo|Furious Division|烈兵団|Retsu Heidan}}. The 31st Division was raised during World War II in Bangkok, Thailand, on March 22, 1943, out of Kawaguchi Detachment and parts of the 13th, 40th and 116th divisions. The 31st division was initially assigned to 15th army (the part of the Japanese Burma Area Army). ActionIn 1944, under Japanese operation U-GO, Lieutenant General Renya Mutaguchi ordered the 31st Division across the border of Burma into British India as part of the overall Battle of Imphal. Its assignment was to capture Kohima, thus cutting off Imphal, and then exploit to Dimapur. The 31st division's commander, Lieutenant General Kotoku Sato was unhappy with his role. He had not been involved in the planning of the offensive, and had grave misgivings about their chances. He and Mutaguchi had also been on opposite sides during the split between the Toseiha and Kodoha factions within the Imperial Japanese Army during the early 1930s, and Sato distrusted Mutaguchi's motives. In addition, along with many of the senior Japanese officers in Burma, he considered Mutaguchi a "blockhead". Starting on March 15, 1944, the 31st Division crossed the Chindwin River near Homalin and moved northwest along jungle trails on a front almost 100 kilometers wide. The left wing of the division, the 58th Regiment, commanded by Major General Shigesaburo Miyazaki clashed with Indian troops of the Indian 50th Parachute Brigade under Brigadier Hope-Thompson in the Battle of Sangshak, on the northern approaches to Imphal on 20 March 1944. The battle continued until 26 March 1944, delaying Japanese advance. Miyazaki's troops were probing Kohima on April 3, completing siege preparations by 6 April 1944. He then launched a series of attacks into the north-east region of the defenses on April 8, and by April 9 the British and Indians had been forced back driven into a small perimeter into what came to be known as the Battle of the Tennis Court. By the night of April 17, the defenders' situation was desperate. However, on the morning of April 18 British artillery opened up against the Japanese positions, which stopped the attacks. To support their counterattack, the British had amassed 38 3.7-inch mountain howitzers, 48 25-pounder field guns and 2 5.5-inch medium guns. The RAF also bombed and strafed the Japanese positions. The Japanese could oppose with only 17 Type 94 75mm mountain guns, with very little ammunition. The road between Dimapur and Kohima had been opened, and the siege was lifted. The Japanese did not retreat at once, but stayed in position and fought tenaciously for several more weeks. By the morning of 13 May 1944, most of the Kohima region had been re-taken by the British forces. Around May 15 the 31st Division began to withdraw, pursued by troops of the British Fourteenth Army. After ignoring orders for several weeks, Sato was removed from command of the 31st Division early in July 1944 and replaced by Uchitarou Kawada. The course of the entire Battle of Kohima was broken off at the same time. Lieutenant General Slim had always derided Sato as the most unenterprising of his opponents, but Japanese sources blame his superior, Mutaguchi, for both the weaknesses of the original plan, and the antipathy between himself and Sato which led to Sato concentrating on saving his men rather than driving on distant and indefensible objectives. The surviving remnants of the 31st Division continued to oppose the British reoccupation of Burma, but for all practical purposes, the 31st Division had largely ceased to exist after the Battle of Kohima.
