Shogakukan is one of Japan's leading manga publishers. The company was founded by Takeo Oga, grandfather of today’s president Masahiro Oga, on August 8,1922, and began in educational publishing with a focus on magazines for elementary school students as well as instructional magazines for teachers. The variety of publications has gradually expanded to pre-school children's magazines, general magazines and book publications such as illustrated reference books, dictionaries and encyclopedias.

Shogakukan is part of the Hitotsubashi Group, a set of interconnected companies with shared business relationships and shareholdings called a Keiretsu. The Hitotsubashi Group also includes several other publishing companies, notably Shueisha. The two companies are headquartered next to each other.

As comic books became increasingly popular in the 1980s and 1990s, Shogakukan expanded with successful fashion and lifestyle magazines such as Oggi and Be-Pal. Today, Shogakukan is one of Japan's major publishers, publishing eighteen comic magazines and about one hundred million comic books a year while continuing to put out an impressive array of non-manga publications.

Shogakukan publishes numerous children's books, dictionaries, and encyclopedias; subjects also include history, folklore, geography, literature, art, education, medicine, photography, and gardening.

Shogakukan publishes 64 magazines and an average of 760 new book titles per year, with sales of 22 million copies from a backlist of 9,200. The publisher sells roughly 117 million copies per year of its 13,900 manga titles, and its lists also include roughly 850 magazine books and 4,000 DVDs and videos.

Analysis & Key Developments


After several years of continuous decline in revenues, and significant losses in 2011 and 2012, Shogakukan managed to stabilize its turnover and return to profitability with revenues of 103 billion JPY. In the process the company cut more than 100 of its employees. Revenues from e-books accounted for 14 billion JPY, which surpassed most of its rivals and matched the larger Kadokawa group.

Following the overall challenging market environment for Japan’s publishing business, Shogaukan shows a continuous decline in its revenues, and a continuous negative operating result.
