DSR

What DSR does

DSR Co., Ltd. (株式会社DSR) is a Tokyo-based system integrator founded in 1969 that specializes in the design, development, operation, and maintenance of insurance, mutual aid (共済), and financial systems. Approximately 80% of project sales revenue derives from the insurance and mutual aid segment, with the remainder coming from securities, trust banks, and investment management institutions served through the proprietary HOP investment trust sales management system (adopted by 22 companies as of April 2020). The company operates as a prime vendor (元請け), engaging directly with customers through full-lifecycle services spanning consulting, requirements definition, design, development, testing, and ongoing maintenance, with deep expertise in mainframe (IBM, Fujitsu, NEC), open systems, and web/cloud environments.

The company's technology portfolio centers on three pillars: (1) custom insurance/mutual aid core system development and modernization, including documented mainframe migrations that have produced 400+ million yen in five-year cost savings for customers; (2) StarCloud, an IaaS-type virtual private cloud service running out of the DSR Tokyo Data Center, with dedicated private-circuit connectivity to AWS, Azure, and Google Cloud for hybrid deployments; and (3) security and infrastructure offerings including manual white-hat vulnerability diagnosis, ransomware-resilient backup solutions, and end-to-end infrastructure build/operation services. Certifications include ISO 9001, ISO/IEC 27001/27017/27018, and Privacy Mark (since 2005), supporting work in regulated financial and insurance workloads.

DSR generates revenue primarily through professional services (consulting, development, maintenance) and managed services (data center, hosting, StarCloud, outsourcing), supplemented by HOP licensing and customization. Pricing is not publicly disclosed and is negotiated per project under multi-year enterprise contracts. The firm has been a wholly-owned consolidated subsidiary of DAIKO XTECH Co., Ltd. (TSE Standard) since 2019, operates with a deliberately small, elite 150-person team (as of April 1, 2026), and markets through direct enterprise relationships, annual DSR Forum industry events, and corporate web/digital channels.
