Overview

Kokudosha (株式会社国土社) is a Japanese publishing house specializing in children's books, educational books, and educational magazines. It traces its origins to 1937, when Taizo Nagamune founded Atokushoin in Mejirodai, Bunkyo-ku, Tokyo. The company changed its name to Kokudosha in 1947 and launched the magazine Kokudo; thereafter it increasingly focused on educational and children's publishing. It joined the Japan Children's Book Publishers Association in 1953, the 'Four Companies Group for Recommending Good Books' in 1957, and the 'Association of Ten Children's Book Publishers' in 1974. The company celebrated its 80th anniversary in 2017 and moved its office to Kanda-Surugadai, Chiyoda-ku, Tokyo, in 2018. Kokudosha's list includes picture books, children's fiction, nonfiction and reference works for young readers, as well as educational titles for teachers and schools. It has published magazines such as Sugaku Kyoshitsu (Mathematics Classroom), Gekkan Shakai Kyoiku (Monthly Social Education), and Rika Kyoshitsu (Science Classroom), and has issued multi-volume series including 'Sekai no Denki' (World Biographies), 'Junior Edition World Masterpieces,' the complete works of Kihaku Saito, and 'Gendai Nihon Doyo Shizenshu' (Complete Collection of Modern Japanese Children's Songs). The company is led by representative Katsuya Tasaki. Its head office is at 2-5 Kanda-Surugadai, Chiyoda-ku, Tokyo. In 2015 Kokudosha applied for civil rehabilitation proceedings; in January 2018 it was announced that the company had become a consolidated subsidiary of Nippon BS Broadcasting (BS11), and that the peer publisher Rironsha was also made a consolidated subsidiary. Today Kokudosha continues to publish children's and educational books under the BS11 group.

History

Kokudosha's history begins with Taizo Nagamune (1901–1986), who founded Atokusha Printing Works in what is now Bunkyo-ku, Tokyo, in 1929. In 1937 he established the publishing division Atokushoin in Mejirodai, Bunkyo-ku. In 1946 he founded Kokudosha, and in 1948 it was incorporated as a joint-stock company, with Nagamune as president. In 1947 the company changed its name to Kokudosha and launched the magazine Kokudo; from then on it increasingly focused on publishing educational books and children's books. In 1951 it launched the magazine Kyoiku (Education) and strengthened its commitment to educational and children's publishing. In 1953 Kokudosha joined the Japan Children's Book Publishers Association. In 1957 it formed and joined the 'Four Companies Group for Recommending Good Books.' In 1974 it formed and joined the 'Association of Ten Children's Book Publishers.' Over the decades it published magazines such as Sugaku Kyoshitsu (Mathematics Classroom), Gekkan Shakai Kyoiku (Monthly Social Education), and Rika Kyoshitsu (Science Classroom), as well as multi-volume series including 'Sekai no Denki' (World Biographies), 'Junior Edition World Masterpieces,' the complete works of Kihaku Saito, 'Tsukuba Tsuneharu Denki Monogatari Zenshu,' and 'Gendai Nihon Doyo Shizenshu' (Complete Collection of Modern Japanese Children's Songs). Nagamune's son-in-law Masaaki Suzuki succeeded him, and later Rimei Suzuki, Yasuo Nishimura, Kenzo Nomura, and Jiro Uchida served as representatives. In 2015 the company applied for civil rehabilitation proceedings.
