What Data Science does
Data Science Co., Ltd. (データサイエンス株式会社, also referred to as DSC) is a privately held Japanese IT services company with approximately 50 years of operating history, founded in the early-to-mid 1970s and headquartered in Konan, Japan, with an estimated workforce of roughly 200–300 employees. The firm delivers a one-stop IT services portfolio organized into six integrated modules: TOTAL SOLUTION (comprehensive infrastructure-to-operations coverage), INFRASTRUCTURE (network and environment optimization), DEVELOPMENT (custom application systems for public, distribution, finance/credit, healthcare, public racing, and financial accounting), EMBEDDED (C, C++, C# development across Linux, Unix, and Windows platforms, including I/O drivers and real-time applications), OPERATION AND MAINTENANCE (ITIL-based 24/365 non-stop operations with service desk), and SECURITY (protection against targeted attacks and internal fraud). Underlying technical capabilities are grounded in long-tenured domain expertise in public racing systems (公営競技) and financial/credit systems, supported by a credentialed workforce of 115 ITIL-certified and 53 information security certified professionals.
The company generates revenue primarily through project-based engagements and managed services contracts with government, financial, healthcare, large enterprise, and SMB clients in Japan. Pricing is quote-based and not publicly disclosed, consistent with enterprise IT services norms. The go-to-market motion is sales-led direct enterprise engagement, with no intermediaries or resellers identified; marketing is conducted through the company website (dscnet.co.jp) and direct email contact. Customer value is positioned around cost-effectiveness relative to large system integrators, single-vendor convenience, and deep vertical expertise in legacy (汎用系) and open (オープン系) systems. The ownership structure is management-controlled, with no disclosed external shareholders, parent company, venture capital, or private equity involvement, and no public listing.
Operationally, DSC is in an active expansion phase: it has executed multiple internal restructurings since 2021—including a major 2021 reorganization that replaced four legacy business divisions with a Technical Services Headquarters, a 2024 second Infrastructure Technology Department, a 2025 Technology Support Department, and a 2026 Security Technology Department—indicating capacity buildout in core service lines. Leadership has rotated three times since 2022 (Ototsuki Narenao to Naito Yuichi in 2022, then to Tomita Hyoei in 2024), and the company has held three consecutive years of Health Management Excellence Corporation certification (2021–2023). No M&A, funding, or international expansion activity is disclosed.
