What Fullness does

Fullness (株式会社フルネス) is a Tokyo-headquartered, privately held Japanese IT training services company founded on June 30, 1997 by Masatoshi Furukawa (古川正寿), who continues to serve as Representative Director and CEO. The company provides instructor-led professional training to Japanese enterprises, mid-market firms, startups, and government-affiliated organizations, positioning itself as an HR development partner that connects technical strategy execution to business value. Its customers include Infosense (software architecture training), ASTEM (SMEs DX training in Kyoto), JGC (engineering/plant software design for DX), COEL (4-month new-hire Java and infrastructure program), Goal connect (Data-Oriented Approach training), Wemex (C# new-hire training), Ryoyo Electro (embedded software fundamentals), and Softage (multi-year C# new-hire program, continuous for six years).

The core offering is curriculum delivery across nine training categories: software design (including domain-driven design and REST API development), software testing and quality (TDD, BDD, Playwright E2E), cybersecurity (fundamentals through DevSecOps), cloud and infrastructure (AWS, Azure, Linux, AWS IoT), programming languages and tools (C#, Java, TypeScript, Next.js, React, Git/GitHub Actions), DX and organizational change, new-graduate training (embedded/microcontroller), and project management (PMBOK-based). Delivery is asset-light, with Fullness employing approximately 9 direct staff and scaling through a recruited network of partner instructors; training is conducted through open-enrollment courses, customized corporate programs, and multi-session interval-based curricula with hands-on exercise ratios of roughly 60–70%. The company also publishes technical books through Japanese publishers including Gijutsu-Hyoron-Sha, Shokodo, and Kagaku Joho Shuppan.

Revenue is generated through professional services — open-enrollment seat sales and customized corporate training — on a quote-based, multi-year contract cadence; pricing is not publicly disclosed and all engagements begin via inquiry form or direct contact. The firm maintains ISO/IEC 27001:2022+Amd 1:2024 and JIS Q 27001:2025 information security certifications (security policy last revised February 19, 2025), supports operations in the Tokyo metropolitan area from its Nishi-Shinjuku headquarters since January 2025, and operates without any disclosed funding rounds, subsidiaries, or acquisitions.
