What NJC SOFTWARE does

NJC SOFTWARE (NJCソフトウェア株式会社) is a Japanese software development company founded in 2001 and operating as a wholly-owned subsidiary of Nihon Jimuki (日本事務器), a group with over 100 years of history. Headquartered in Tokyo with 11-50 employees, the company performs 100% in-house development of cloud-based enterprise systems across three primary verticals: healthcare (CARNAS health checkup platform, electronic medical record systems), public-sector fisheries (MMH integrated cooperative management platform), and private enterprise ERP (COREPlus NEO 2.0 for mid-market and SMB clients). Core technology comprises multi-tenant cloud architecture with API-based external integration capabilities.

The company's product portfolio includes CARNAS, a multi-tenant cloud service supporting health examination operations at general hospitals, health checkup centers, and clinics; MMH, an integrated platform managing sales, purchasing, ice-making, refrigeration, and credit/debt operations for fisheries cooperatives; and COREPlus NEO, a cloud ERP integrating order, inventory, and shipping for mid-market enterprises with industry-specific templates. Revenue is generated through SaaS/cloud subscriptions (CARNAS, COREPlus NEO), custom system development (electronic medical records, health checkup systems), and on-premise licensing with maintenance (MMH). Pricing is quote-based and not publicly disclosed.

NJC Software distributes exclusively through its parent company Nihon Jimuki, which manages customer-facing sales and relationships across medical institutions, fisheries cooperatives, and private enterprises. This allows NJC Software to focus on development and maintenance while leveraging the parent's established enterprise network. The company also pursues custom AI development, notably the AI Librarian (AI司書) project for a university client. FY2025 revenue was 538 million yen, with operational metrics including 12 years 2 months average tenure, 128 annual holidays, and zero new graduate turnover over the past three years.
