The organization's name means “let’s go together” or “we shall fight this war side by side,” and derives from a line in an old Chinese poem recorded in the Book of Odes.


History


Before World War II

On 15 February 1877 not long after the formation of the
Imperial Japanese Army The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor o ...
a Kaikosha was founded in Kudan in Tokyo as a meeting place for officers and as a reception hall. After that Kaikosha groups cropped up at divisional headquarters across the country. Kaikosha was soon incorporated and set about providing aid to wounded soldiers, supporting temples that consecrated war dead, publishing academic research and essays on military topics, and fostering friendships among fellow officers both in active service and in the reserves. These activities were funded by membership fees. Kaikosha was a major organization and also a sort of company that engaged in the manufacture and sale of military equipment, especially clothing, for officers. In addition to the basic tailor-made clothes, Kaikosha sold ready-made clothes that became popular at the time of World War II. Tags were attached to Kaikosha-made clothing upon which a symbol such as a cherry blossom or pentagram was emblazed across the letters “Kaikosha,” “Rikugun Kaikosha Gunjubu,” “Kudan Kaikosha,” or “Osaka Kaikosha Shuhobu.” Kaikosha stores also sold every variety of uniform, as well as military caps, gloves, boots, sabres, pistols, holsters, binoculars, and memorabilia from military exercises and parades, among other things. All these Kaikosha-made good were widely used by military officers. Kaikosha also ran schools, inns, and cafes for use by officers and related individuals. The Osaka Kaikosha, which was linked with the 4th Division, owned a private elementary school for the sons of officers who desired to enter military academies which became so distinguished that eventually it admitted the sons of wealthy bankers, lawyers, and doctors as its primary students. After the war it became Ōtemon Academy Elementary School. The Asahikawa Kaikōsha Fuzoku Hokuchin Shōgakkō, now called the Asahikawa Shiritsu Hokuchin Shōgakkō, and the Hiroshima Kaikōsha Fuzoku Seibi Shōgakkō were also prestigious elementary schools.


After the war

Due to the defeat in the Second World War Kaikosha disbanded for a time, but starting around the year 1951 interested veterans were coming together and in the year 1952 they revived their group under the name Kaikokai in order to continue the traditions of the Imperial Japanese Army. However, on 28 December 1957, at the same time as the new organization was formally incorporated, they returned to their original name. By contrast, the Suikosha, which represented officers of the Imperial Japanese Navy before the war, also resurrected around the same time but changed its name permanently to Suikokai. Because the Kaikosha was originally an organization for members of the Imperial Japanese Army, after the war full membership was limited to its veterans. However, the aging of the membership continued unabated and by 1992 the organization was down to 18,715 members, 500 of whom were passing away each year. Finally at a council meeting in the year 2001 the rules were amended and retired members of the air and ground wings of the Japan Self-Defense Forces became eligible for full membership. Nonetheless, at the end of the year 2006 only about 630 former members of the JASDF or JGSDF were members, whereas Kaikosha's naval equivalent, the Suikokai had brought people associated with the
Japan Maritime Self-Defense Force , abbreviated , also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) ...
, including active members and their family, up to half of its total membership. However, Kaikosha finally went ahead and delved into the carrying on of its traditions while eyeing eagerly plans to revise the Japanese constitution. In April 2006 the Chief-of-Staff of the Ground Self-Defense Force released a message to each unit requesting them to help Kaikosha and within the year 2007 400 new members joined. At the end of March 2010 Kaikosha had 10,000 members of whom 1,000 were former members of the JASDF or JGSDF.
