The 1st Infantry Division was formed in
Tokyo in January 1871 as the nihongo|Tokyo Garrison|東京鎮台|Tōkyō chindai, one of six regional commands created in the fledgling Imperial Japanese Army. The Tokyo Garrison had responsibility for the eastern region ofHonshū (Kantō region ), centered on the Tokyo metropolitan area. The six regional commands were transformed into divisions under the army reorganization of14 May 1888 , based on recommendations by thePrussia nmilitary advisor Jakob Meckel to the Japanese government.As one of the oldest Divisions in the Imperial Japanese Army, the 1st Infantry Division saw combat in the
First Sino-Japanese War and theRusso-Japanese War and the Nonomhan Incident.The
February 26 Incident was an attemptedcoup d’etat staged by elements of the 1st Infantry Division in Tokyo in 1936.From 1937, the 1st Infantry Division was stationed in
Manchukuo , where it came under the command of theKwangtung Army , and where it was assigned to guard the northern border of Manchukuo against theSoviet Union .During later stages of the
Pacific War the 1st Infantry Division was reassigned to thePhilippines , and initially based inManila where it formed the core of GeneralTomoyuki Yamashita 's 14th Area Army. Ordered to oppose the re-occupation ofLeyte by the American and Filipino forces, the 1st Infantry Division landed atOrmoc City on the west coast of Leyte on1 November 1944 . Their orders were to move up Leyte Highway Number 2 toCarigara and to secure the northern half of the island. However, American and Filipino forces had already seized Carigara, and American air strikes had deprived the Japanese 1st Infantry Division of its supply chain and reinforcements. Unable to reach Carigara, the Japanese fortified hilltops and ridges along the highway, and defended these areas against the US offensive from7 November 1944 though12 December 1944 , in fierce combat, including combat in the middle of atyphoon . By the time Leyte was secured by American and Filipino forces, of the 11,000 Japanese soldiers sent to theBattle of Leyte , only 800 remained alive. Following the Battle of Leyte, the 1st Infantry Division ceased to exist as an operational unit.Some of the more noteworthy commanders in the history of 1st Infantry Division include:
