Kirihara Shoten

What Kirihara Shoten does

Kirihara Shoten (株式会社桐原書店) is a Japanese educational publisher founded in 1966/1967 in Tokyo, specializing in Ministry of Education (MEXT)-certified English and Japanese language textbooks and supplementary learning materials. The company primarily serves Japanese high schools and universities through the formal textbook adoption system, supplemented by consumer book sales through bookstores. Its product portfolio spans certified textbook lines (Heartening for English, Kokugo textbooks for Japanese language), flagship grammar references (FACTBOOK, Next Stage, Bright Stage), vocabulary builders (Database 3300/4800/TOEIC), reading comprehension series (SKYWARD, Long Run Reading, Reading Flash), listening training (HyperListening, Audio Book Library), composition training (English Composition High Training), and examination preparation materials targeting Japan's Common Test for University Admissions, TOEIC, TOEFL, and university entrance exams.

The company's technology stack comprises a digital ecosystem layered on its print textbook business, including the KIRIHARA Online Academy subscription service, the Kirihara no Mori cloud learning platform and Mori no Test cloud-delivered assessment service, audio learning apps (LISTENING PRACTICE and Gakken's my-oto-mo), the Kirihara AI Writing Test assessment series, digital textbooks, and the TestMaker4 teacher data portal with Google Forms and Microsoft Forms integration. The company holds Privacy Mark certification (JIS Q 15001 compliant, renewed December 2025) for handling personal data across cloud services and essay grading operations.

Kirihara Shoten generates revenue primarily through one-time textbook licensing under MEXT's textbook adoption system, unit-priced supplementary materials (ranging from approximately 638 yen to 2,090 yen per item), subscription-based digital services, professional essay review and grading services for high school students, and consumer book sales through physical bookstores and online retail. Sales-led distribution operates through five regional sales offices (Sendai, Saitama, Osaka, Hiroshima, Fukuoka) and major Japanese textbook wholesalers including Tohan Corporation and Nihon Kyohan, with additional consumer reach via Rakuten Books Network. The company is a wholly-owned subsidiary of Gakken (since 2024), previously under Toppan Holdings/Kolle (2017–2024), and prior to that under the Pearson Group (2000–2013). As of March 31, 2025, the company had 104 employees and 96 million yen registered capital; financial results are not publicly disclosed.
