What Nihon System Research does

Nihon System Research, operating commercially as PCI Solutions, Inc. (PCIソリューションズ株式会社), is a Tokyo-based Japanese IT services firm founded in 1991 and operating as a subsidiary of PCI Holdings (PCIホールディングス株式会社). The company is structured around an Engineering Business (embedded systems for automotive, construction machinery, networks, devices and control equipment; enterprise solutions for financial, manufacturing/distribution, public sector, social infrastructure and IT infrastructure), an ICT Solutions Business (IoT/IoE and product solutions including IT asset management and cybersecurity via AppGuard), and an Education Business (technical training including PMP certification preparation and project management programs).

Underlying technology spans embedded control software, enterprise system design (mainframe through smart device), IoT/IoE integration, AWS-based serverless architectures, and an emerging portfolio of AI products: Voice AI Agent for Amazon Connect (generative AI-driven call automation), Skill-Puzzle (AI personnel scheduling, claimed ~90% reduction in planning time), Raku-RAG (private/isolated generative AI that does not expose internal data), and Mekiki-Baito (computer vision for manufacturing visual inspection). The portfolio covers text, audio and image modalities and integrates with Amazon Connect and the AWS cloud stack.

Revenue mechanics are mixed: professional services revenue from custom engineering and training engagements, complemented by subscription/recurring revenue from productized AI and cybersecurity offerings (AppGuard). Go-to-market combines direct enterprise field sales across large financial, manufacturing, public-sector and infrastructure clients with a productized/self-serve channel through the corporate website (pci-sol.com) for AI products. Distribution is domestic Japan only (Tokyo metropolitan area), supported by AWS Summit Japan event participation and earned media in publications such as QOL VIEW. The company is announced for merger with parent PCI Holdings on July 3, 2026, which will materially alter its corporate structure.
