HAZUKI SYSTEM

What HAZUKI SYSTEM does

HAZUKI SYSTEM Corporation (葉月システム株式会社) is a privately held Japanese IT services company headquartered in Omiya-ku, Saitama-shi, founded in December 2012 by IT professionals who previously worked in the IT department of an automobile manufacturer. The firm operates with 1-10 employees and 10 million JPY of registered capital, offering a one-stop IT service that spans system planning, custom software development, infrastructure construction (network, server, and data center), technical engineer dispatch (技術者派遣/haken), information equipment resale (including Microsoft products), and system-introduction consulting. Its primary customer base is in the manufacturing sector — specifically automobile manufacturers and parts makers — with UD TRUCKS Corporation disclosed as a client relationship dating to April 2013.

The company's proprietary product portfolio comprises U.PaS (launched August 2013), Shuwa Chi / 手話っち (a sign-language support system for hearing-impaired individuals, published November 2016), and Wonderful Manager, a management tool. Shuwa Chi is accompanied by repeated annual sponsorship of the National High School Sign Language Performance Tournament, indicating social-contribution positioning in the accessibility segment. Distribution is primarily direct enterprise sales, supplemented by a 2013 distributor agreement with Usuk System Corporation (ユーサックシステム株式会社). Pricing is not publicly disclosed and follows a contact-based engagement model typical of bespoke Japanese IT services.

Operationally, HAZUKI SYSTEM holds ISMS certification (JIS Q 27001:2014, obtained October 2021, migrated to JIS Q 27001:2023 in October 2024) and serves the Kanto region of Japan only with no international footprint. Leadership is led by Representative Director and President 大川充伸 (Okawa Mitsunobu) with 棚沢公勝 (Tanasawa Kimikatsu) as a board director; an executive organizational change occurred on April 1, 2025. No venture capital or institutional investment, no M&A, no disclosed revenue, and no AI/ML capabilities are identified in the source material.

Broad incumbents

• NTT Data Corporation: Global system integration and consulting arm of NTT, with strong presence across Japanese automotive and manufacturing. A broad incumbent that competes for large digital transformation and infrastructure programs.
• Fujitsu Limited: Japan's largest IT services and hardware vendor, serving automotive manufacturers globally. Competes for many of the same enterprise and manufacturing IT contracts as HAZUKI but with vastly broader capabilities and scale.

Direct peers

• DTS Corporation: Japanese independent IT services company offering system development, infrastructure, and embedded solutions to manufacturing and enterprise clients. Comparable mid-sized peer with similar service-line breadth.
• Otsuka Corporation: Mid-sized Japanese IT services firm combining custom system development with information equipment sales (including Microsoft products) and network infrastructure — a closely matching business model to HAZUKI's five-service mix.
• BIPROGY Inc. Mid-to-large Japanese system integrator with a long heritage in custom programming, infrastructure, and managed services for enterprise customers. Directly comparable in IT services mix, though at larger scale.
• TIS Inc. Independent Japanese IT services group offering custom development, consulting, and infrastructure services across multiple industries including manufacturing. Comparable in business model and customer profile.
• SCSK Corporation: Major Japanese system integrator serving automotive OEMs, financial services, and manufacturing. Overlapping offerings in custom development, infrastructure, and IT staff dispatch make it a direct competitor for similar contracts.
• ULS Group, Inc. Smaller Japanese IT services group with consulting, system development, and infrastructure offerings to enterprise clients. Closely comparable size and service mix to HAZUKI.
• NS Solutions Corporation: IT services arm of Nippon Steel with deep exposure to Japanese manufacturers including automotive clients. Closely comparable in the automotive/manufacturing IT services vertical, but at materially larger scale than HAZUKI.

Emerging players

• Internet Initiative Japan (IIJ): Japanese network and cloud infrastructure provider. Overlaps with HAZUKI's infrastructure construction and network services but does not directly compete in custom business system development.
