ISD

What ISD does

ISD is a privately held Japanese IT services company (株式会社国際システム / International Systems Development Co., Ltd.) founded in October 1982 and headquartered in Naha, Okinawa. It is 68.75%-owned by BIPROGY Corporation (formerly Japan Unisys), making it a core member of the BIPROGY Group. The company employs 174 people as of April 1, 2025 and operates from three sites: the Naha headquarters, a Tokyo sales office inside the BIPROGY building, and the Uruma City Development Center in Okinawa IT Shinyaku Park (established September 2021, 60-seat capacity with dedicated server room and three-level security).

ISD's business spans four service lines: (1) custom system development for banks, securities firms, insurers, wholesalers, retailers, logistics providers, food and materials manufacturers, and local governments; (2) IT infrastructure construction across on-premise, cloud, network, and security; (3) maintenance and 24/7 operations support; and (4) Sasuga Cloud, a proprietary sales and logistics management SaaS for the wholesale sector, originally released in 1996 and certified as a Level 1 business app under Japan's SME common EDI standard in April 2022. The technology stack is mainstream enterprise (Java, .NET, COBOL, PHP, Delphi, UiPath RPA, Oracle, SQL Server, PostgreSQL, MySQL, IntraMart), and delivery combines local Japanese teams with offshore resources in China and Vietnam to capture nearshore cost advantages.

The company monetizes primarily through project-based professional services for enterprise and government clients, plus a subscription line from Sasuga Cloud (initial implementation starting at 1,000万円 and recurring monthly fees starting at 15万円). Distribution is sales-led: direct enterprise field sales to large accounts, the BIPROGY Group channel for nationwide reach, and inside-sales inquiry forms for Sasuga Cloud mid-market prospects. Certifications include ISO/IEC 27001:2022, ISO 14001:2015, JIS Q 15001:2023 Privacy Mark, JIS X 8341-3:2016 AA web accessibility, and the SME common EDI Level 1 business app certification. Revenue figures are not publicly disclosed, and the company has no external funding rounds, operating as a profitable, dividend-paying subsidiary within the BIPROGY Group.
