What Nippon Computer Systems does

Nippon Computer Systems (NCS, 日本コンピュータシステム株式会社) is a Japanese IT services firm founded December 25, 1980, and headquartered in Toranomon, Tokyo. It provides project-based IT services across six business divisions: Finance, Social Infrastructure, Public, Enterprise, Cloud, and Platform, primarily to Japanese megabanks, securities firms, insurance companies, telecom carriers, electric power companies, central and local government entities, and manufacturers. Roughly 85% of NCS developers are deployed on-site at client locations, and the firm holds nationwide unified tender qualification rank A for all ministries. The company operates from a Tokyo headquarters, a Kuramae Development Center in Tokyo, and an Osaka Development Center, with 606 employees as of April 1, 2026, and reports FY March 2026 sales of ¥8,661 million.

NCS runs a hybrid revenue model combining professional services with a portfolio of proprietary and partner-resold software products. Proprietary products include the Maplet GIS engine (with vertical variants such as Maplet SM for bridge inspection, co-developed with Sumitomo Mitsui Construction), the iQUT construction site management cloud service launched in July 2022, and the PM塾 PMP certification training program. Partner-resold products include mcframe (manufacturing ERP from Business Engineering, where NCS has held engineering and business partner status since 2008/2017 and No.1 MCCP certification holder position for five consecutive years), PowerBuilder (low-code IDE where NCS has been the domestic exclusive distributor since 2012, serving 1,400+ Japanese organizations), CELF (SCSK no-code platform, Advanced Partner status as of 2025), and OpenText enterprise information management products.

NCS became a wholly-owned subsidiary of N.D. Software (NDS) in 2011 following a December 2008 MBO and JASDAQ delisting. NDS in turn joined SOMPO Holdings Group in 2023, placing NCS within one of Japan's largest insurance and services conglomerates. The company has maintained debt-free operations for seven consecutive years as of April 2026 and reports an average employee tenure of 10.5 years, indicating stable long-term customer and employee relationships.
