What ITbook does

ITbook Co., Ltd. is a Tokyo-based Japanese IT consulting firm that has served the public sector since its 1990 founding (originally as Duo System). The company operates as a wholly-owned subsidiary of SAAF Holdings following a 2018 business integration that took it private after a prior listing on the Tokyo Stock Exchange Mothers Market (2004-2018).

ITbook delivers twelve consulting service lines that span the full lifecycle of public-sector IT projects — from basic-concept planning and requirements definition through procurement support, project management, information security, government-cloud operations management, and AI / IT governance. Domain-specialized service lines address municipality standardization, local-government DX promotion, disaster-prevention DX, education DX, healthcare DX, and electronic procurement system design. The firm's technology stack leans on partnerships with Amazon Web Services (Select Tier partner since February 2025) and Oracle (OPN member since January 2026) to deliver government-cloud migration and management, complemented by ISO-certified processes (ISO 9001, 14001, 27001, 42001, plus Privacy Mark).

The business model is a professional services engagement model: project-based, custom-quoted consulting work delivered directly to Japanese local municipalities (the primary segment), central government agencies, and quasi-public organizations. There are no resellers, marketplaces, or OEM channels. Five branch offices (Tokyo HQ, Osaka regional HQ, Kobe, Nagoya, Kumamoto) provide nationwide coverage, and the firm is actively investing in AI governance advisory as a next growth vector following its 2026 ISO/IEC 42001 certification.
