What KSC does
KSC Co., Ltd. (株式会社KSC) is a Japanese system integrator (SI) founded in 1987 and headquartered in Osaka, with regional offices in Tokyo (Kanto) and Kyoto (sales). The company provides end-to-end enterprise IT services—consulting, system design, development, implementation, and ongoing maintenance—targeting mid-market and enterprise clients across manufacturing, retail/wholesale, and services industries. KSC's core competency centers on ERP (Enterprise Resource Planning) implementation, supporting back-office functions such as sales management, production management, accounting, human resources/payroll, and logistics. The company operates as both a custom system developer (Java/.NET, ASP.NET, SQL Server) and a value-added integrator/reseller for leading Japanese ERP platforms including GRANDIT, EXPLANNER (NEC), ProActive, and MCFrame, complemented by a database administration (DBA) practice and a security systems business line built around image processing applications (vein authentication, facial recognition, video surveillance).
KSC's technology stack is anchored in established enterprise frameworks rather than emerging platforms, leveraging Java, .NET, ASP.NET, SQL Server, Oracle, and DB2 across its system integration, DBA, and security system operations. The company maintains partner-of-record status with major ERP vendors (NEC, System Integrator) and technology vendors (IBM, HP, Oracle, Microsoft, Lenovo), holds ISO 27001 (ISMS, acquired 2009) and Privacy Mark (acquired 2017) certifications, and benefits from a Microsoft Certified Partner designation. Current capitalization is ¥25 million following the 2010 merger with Itec System Co., Ltd., which transformed the prior entity (Kyoto Software Corporation) into the present Kabushiki Kaisha KSC; the company is privately held with no external private equity or venture capital ownership disclosed in source material.
KSC generates revenue through professional services across four business lines: System Solution (custom development using Java/.NET), Package Business (ERP implementation and customization for GRANDIT/EXPLANNER/ProActive/MCFrame), DBA Services (database consulting on Oracle, SQL Server, DB2), and Security Systems (biometric image processing and video security). Pricing is quote-based and not publicly disclosed. Go-to-market combines direct enterprise field sales with channel partnerships—ERP vendor relationships (NEC Business Partner, GRANDIT Business Partner, ProActive Business Partner, EXPLANNER Support Partner) provide distribution and credibility, while sales agent agreements with IBM Japan, HP Japan, Lenovo Japan, Rakus, and Oukan extend reach into technology product sales and SaaS distribution (奉行, 大臣). KSC employs 100 staff (150 including group companies Technical Software Consultant and Kobe Techno Serve) and has earned consecutive "A-Level Enterprise" recognitions from Tokyo Shoko Research in the 2020, 2022, and 2023 Kansai edition listings, placing it among the top 8% of companies in that region.
