The Imperial Japanese Army (IJA) initially purchased foreign tanks for evaluation during World War I, and began developing its own indigenous designs during the late 1920s. Due to the war with China, Japan produced a large number of tanks. Although initially the Japanese used tanks to good effect in their campaigns, full-scale armored warfare did not occur in the Pacific and Southeast Asian theaters as it did in Europe, and tank development was neglected in favor of naval activities. The best Japanese designs were never used in combat as they were kept back in expectation of defending the Japanese Home Islands. == Initial tank procurement == Near the end of World War I, the Japanese showed an interest in armored warfare and tanks and obtained a variety of models from foreign sources. These models included one British Heavy Mk IV and six Medium Mark A Whippets, along with thirteen French Renault FTs (later designated ''Ko-Gata Sensha'' or "Type A Tank"). The Mk IV was purchased in October 1918 while the Whippets and Renaults were acquired in 1919.〔Zaloga, p.4〕 Trials with these vehicles were successful, and the Army decided to establish an armored force in 1925, planning to form three light tank battalions and one heavy tank battalion. However, the greatest problem was equipping these units, as the Japanese did not have any indigenous tank production capability. The IJA therefore sent a mission to purchase more tanks from Britain and France, requesting newer designs. However, the newer tanks were not available as these countries had difficulties supplying them to their own armored forces, and the only available model was the older Renault FT.〔Hara (1972), p. 3〕 The Japanese reluctantly imported these but in 1929 they were able to acquire ten examples of its successor, the Renault NC1 (designated ''Otsu-Gata Sensha'' or "Type B Tank"). Both types of tanks were still in active service in 1940, and additional vehicles and spare parts were obtained after the Japanese occupation of French Indochina. The Japanese also purchased several Vickers 6-Ton tanks and Carden Loyd tankettes and used these as a basis for further development, resulting in tanks such as the Type 89 Chi-Ro. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Japanese tanks of World War II」の詳細全文を読む スポンサード リンク
