What NDK ITS does
NDK ITS (NDKイッツ株式会社) is a Tokyo-based IT systems integrator founded in July 1989 as a spin-off of the computer division of Nihon Densetsu Kogyo Co., Ltd., a TSE Prime-listed railway electrical construction company. The firm is a wholly-owned subsidiary of Nihon Densetsu Kogyo and operates with 99 employees (as of April 2026) and registered capital of ¥40 million. Its core business spans four service lines: system development, infrastructure construction, IT consulting, and operation & maintenance, with a sustained strategic emphasis on serving the parent's captive IT requirements and the broader JR East-affiliated rail ecosystem.
The company's flagship product is Thomas Plus (トーマスPlus), an integrated management information system (ERP) developed and launched in July 2024 after roughly three years of build-out involving more than 100 engineers. Thomas Plus replaces legacy systems across finance, human resources, and operations for Nihon Densetsu Kogyo, and is positioned to extend to JR East group companies. Adjacent offerings include railway equipment management systems tailored to JR East-aligned customers. Technology architecture is built on mainstream enterprise stacks: Java, C#, Python, PHP, C++, and VB.NET on the application side, with Oracle, SQL Server, and PostgreSQL on the data side, and Microsoft 365, Azure, Power Platform, and Dynamics 365 as the productivity and platform backbone. Operations are concentrated in the Kanto region with headquarters in Bunkyo-ku, Tokyo.
NDK ITS's business model is fundamentally a captive IT services and platform provider. Revenue is generated predominantly through project-based system development and long-running operation & maintenance contracts with its parent and JR East-related entities — approximately 98% of revenue is concentrated in this single ecosystem. Commercial expansion beyond this captive base is constrained by design: most external-facing activity is opportunistic system integration with adjacent JR East affiliates rather than independent enterprise sales. The firm is pursuing ISMS certification alongside its existing Privacy Mark credential (held since February 2013), and has begun piloting safety-culture VR and robotics training as an adjacent product surface.

NDK ITS competitors and assessment
Company assessmentBroad incumbents
- BIPROGY Inc. Japanese SI providing enterprise applications, infrastructure construction, and managed services primarily to financial, public, and industrial clients. Comparable as another large Japanese SI competing for similar end-to-end SI/outsourcing engagements in construction-adjacent and infrastructure customers.
- Fujitsu Limited: Major Japanese SI and ERP/cloud services provider with deep enterprise and public-sector penetration. Comparable as an incumbent able to displace or partner with smaller niche SIs on ERP migration, infrastructure, and managed services engagements in construction and transportation.
- Hitachi Solutions: Japanese SI focused on Microsoft Dynamics, ERP, and cloud services for mid-to-large enterprises. Closely comparable because NDK ITS sells similar Microsoft-stack (Dynamics 365, Azure, M365) ERP and migration services; Hitachi Solutions is the broader-scale analog of the same offering.
- NTT Data Group: Largest Japanese systems integrator offering enterprise application services, ERP implementation, cloud, and managed services across all verticals. Comparable as a broader incumbent that can credibly compete for ERP, SI, and managed services mandates inside construction and railway groups that NDK ITS currently serves.
- TIS Inc. Diversified Japanese SI providing consulting, system development, and managed services across industrial and financial verticals. Comparable as a mid-to-large Japanese peer competing for the same enterprise SI, ERP migration, and managed services RFPs that NDK ITS pursues outside its captive parent base.
Direct peers
- ITFOR Inc. Mid-sized Japanese systems integrator offering custom development, infrastructure, and managed services to industrial and financial clients. Comparable because NDK ITS occupies a similar niche tier: a focused, multi-vertical-capable Japanese SI rather than a top-tier incumbent.
- NS Solutions: Industrial-vertical IT systems integrator with deep domain expertise in steel, manufacturing, and infrastructure. Comparable because NDK ITS operates a similar model: captive parent-group SI focus on industrial/construction domains, end-to-end development through managed services, and Microsoft-stack-aligned delivery.
- OBIC Business Consultants: Japanese systems integrator specializing in OBIC ERP implementation, consulting, and custom development for mid-market and enterprise clients. Directly comparable because NDK ITS partners with sister OBIC (the ERP vendor) to deliver Thomas Plus and similar ERP migration / customization projects.
- JR East Information Systems: IT subsidiary of JR East handling railway operations, station, and back-office systems. Comparable because it sits on the customer side of NDK ITS's JR East relationship and operates an analogous vertically-integrated SI model serving a parent railway group's IT needs.
Emerging players
- Future Corporation (Future Consulting): Japanese IT consulting / systems integrator with strong emphasis on ERP migration and digital transformation for mid-sized Japanese enterprises. Comparable as a peer pursuing similar ERP-package migration and cloud modernization mandates that NDK ITS also targets in its 'other enterprises' segment.
