Gyosei

What Gyosei does

Gyosei Corporation (株式会社ぎょうせい) is a Japanese publishing and information services company founded in 1893 and headquartered in Koto Ward, Tokyo. The company operates across five business segments: comprehensive publishing (loose-leaf subscription books, single-volume books, magazines, and self-publishing), digital content services (e-books, electronic databases, PLAT Tax Services, and the Gyosei Electronic Bookshelf platform), law/regulation/corporate legal services (Super Reiki-Base ordinance support, Discuss meeting minutes search, Toben Link assembly answer review, and the Super Reijo-web current legislation database), local government information systems (financial accounting, HR/payroll, bond management, public enterprise accounting, water billing, and electronic approval/contract services), and regional revitalization services. Core products target Japanese local government employees, legal professionals, tax accountants, and educators with authoritative content on laws, regulations, and municipal administration.

The company's revenue model blends subscription recurring streams (loose-leaf supplements, monthly and bimonthly magazine subscriptions priced around ¥30,000/year for professional titles, digital database subscriptions, and municipal IT system contracts) with one-time book sales through shop.gyosei.jp e-commerce and bookstore partners, plus advertising sold to businesses targeting government and professional audiences. Go-to-market is sales-led with direct institutional sales to municipalities, schools, and professional associations alongside content marketing through owned media (Gyosei Online, Education Library) and segmented newsletters.

Gyosei's strategic position is built on a 130+ year content library, deep editorial specialization in Japanese public-sector law and administration, and entrenched relationships with institutional buyers including co-branded publications with the Japan Tax Accountants Association and standards work with the Japan Building Administration Council. Key technology assets include proprietary databases for Japanese laws and regulations, municipal ERP-type systems deployed at scale across Japanese municipalities, and a partnership-driven digital content distribution model (TKC Law Library, PLAT Tax Services). The company is privately held with no disclosed external investors and a leadership team headed by Representative Director & President Koji Shigeyoshi (西本 功二).
