NDB

What NDB does

NDB (Nippon Day Break Co., Ltd., 日本デェイブレイク株式会社) is a Tokyo-headquartered private Japanese IT services firm founded in October 1976 and operating as a software vendor (ソフトウェアベンダー). The company provides end-to-end information system lifecycle support — consultation, development, introduction, operation, and maintenance — to large Japanese enterprises either directly or via subcontracting arrangements with major system integrators. As of April 2026 NDB has 218 employees and operates from a Tokyo headquarters in Minato-ku (Shiba) and a Sapporo business office in Hokkaido.

The company's three core service lines are: (i) Information System Development & Implementation (requirements definition through deployment), (ii) On-site Service dispatching qualified personnel to client locations for system planning, development, maintenance, and IT infrastructure operations, and (iii) Consultation Service, including Earned Value Management (EVM)-based project management and bidding/inspection proposal support. Technical breadth spans mainframe environments (IBM, NEC ACOS4), Unix variants (HP-UX, Solaris, Linux, NetBSD, OpenBSD), Windows Server, and mobile (Android); languages including C, C++, COBOL, Java, C#, Python, JavaScript, and COBOL-era Pro*C/Pro*COBOL; databases (Oracle, SQL Server, DB2, MySQL, PostgreSQL, IMS/DB); middleware (IIS, Apache, WebLogic, WebOTX, Tomcat); and RPA tooling (UiPath, BizRobo!, WorkFusion). Domain specialization is concentrated in property-and-casualty insurance (Guidewire platform) and in manufacturing/automotive mission-critical systems.

The business model is professional services: revenue is generated through contracted software development projects, on-site staffing arrangements, and project-management consulting. GTM is dual-track — direct enterprise contracts with major end-user corporations, and subcontracting under SIer-led delivery frameworks. NDB is a wholly owned operating subsidiary of NDB Holdings Co., Ltd. (established March 2011), which also oversees group companies Acronet and USE. Certifications include ISO 9001, ISO 27001 (ISA IS 0269), and Privacy Mark (Registration No. 10820968); a General Worker Dispatching Business Permit (派13-305590) authorizes on-site staffing operations. Operations are confined to Japan, with the Sapporo office being the only regional location beyond Tokyo. FY2025 revenue was 5.26 billion JPY, up from ~2 billion JPY a decade earlier.
