“Corporate-based rugby, which began at the end of the Taisho era, was the beginning of company rugby. The pioneers of company rugby include companies such as Tokyo Denki established by a Waseda graduate, Koichi Onoda, Aikoku Seimei founded by Kiyoshi Omachi, and Joban Seimei founded by a Keio graduate, Tatsuzo Kitajima. Records tell us that the Joban Seimei rugby team had more than 20 matches in its first two years. In Hakodate, Hokkaido, Nichiro Gyogyo founded a rugby team followed by Hokkaido University ealier in 1926, according to the initiative taken by a Keio graduate, Saihei Oishi. He also had Hokkaido Colliery & Steamship set up a rugby team.
As for governmental entities, the Ministry of Railways and Totetsu took the initiative in this regard. When Keijiro Ishida, who graduated from the University of Tokyo in 1925, was called to the main office of the Ministry of Railways to give a lecture about rugby in January the same year before he found a job. The participants of this lecture got so excited that it immediately turned to the ceremony to found a new rugby team. Eventually, including the main office of the ministry, rugby teams were formed in three railway bureaus in Tokyo, Osaka, and Monji. They held their first rugby tournament at the Koshien Stadium in February 1930. In addition to the above-described teams, those JRFU member teams at that time around 1933 were life insurance firms including Nisshin, Teikoku, Chiyoda, Daiichi, Yasuda, and Meiji, fire insurance firms including Tokyo Marine, Tokyo, and Taihei, and electric-related companies including Toho Electric Power Company, Oji Denki, Fuji Electric, and the Electro Technical Laboratory of the Ministry of Communications. There were other companies that also had rugby teams, such as Shibaura Seisakusho, Japan Broadcasting Corporation, Okuragumi, Columbia Pictures Industries, Matsuzakaya, Shirokiya, Sanseido, Kimuraya, Shoujikisya, Kawasaki Daihyaku Bank, Shokin Bank, Tonichi Shimbun, Tokyo Asahi Shimbun, and Osaka Mainichi Shimbun.” (Source: “History of Japanese Rugby”)
