What JmacSoft does

JmacSoft Corp. (株式会社ジェイマックソフト) is a privately held Japanese system integrator founded in 1963 as part of a Daiko Bank 20th anniversary initiative, incorporated separately in 1983 and renamed to its current form in 2008. The company delivers custom enterprise business systems covering production management, sales/logistics, supply chain management, financial accounting, and HR/payroll, with end-to-end engagement from system consulting and design through programming, testing, documentation, operation guidance, and ongoing maintenance. Approximately 80% of its customers are Tokyo Stock Exchange-listed companies or their group companies, drawn from banking, insurance, construction, food, pharmaceutical, transportation equipment, electrical machinery, chemical, retail, and public-sector verticals.

The technology stack is built around proprietary custom development, packaged resold NEC software (EXPLANNER/Ax series for accounting and HR/payroll; ProActive ERP), and several in-house solutions including RFID-based inventory and tracking, cloud-managed Electronic Shelf Labels (ESL), the KEIROKA travel expense application system (which applies the Weber-Fechner law to route selection), the Asudoco action plan management tool, the Teresa health management mobile app, and the relatis web data calculation application. The company also operates contract calculation services with approximately 30 years of accumulated mainframe and computer-based payroll, bonus, and year-end adjustment processing expertise, and is an authorized NEC dealer for OA equipment sales. Certifications include ISO9001 (since September 2003) and ISO/IEC27001 (since April 2010).

JmacSoft's business model is heavily weighted toward professional services: 97.6% of FY March 2026 revenue (¥2.394 billion) came from software development, 2.1% from OA equipment sales, and 0.3% from information processing services. Distribution is direct enterprise sales led by SI sales representatives and system consultants, primarily targeting TSE-listed enterprises in the Tokyo metropolitan area. The company is headquartered in Nagaoka, Niigata Prefecture, with five additional offices in Niigata, Kashiwazaki, Tokamachi, Joetsu, and Tokyo, and operates with 235 employees as of April 1, 2026. A workforce of 357 nationally certified and vendor-certified IT professionals supports delivery, with average tenure of 20.1 years and a 1.8% separation rate signaling unusually high retention for the SI sector.

Expansion highlights5 records

Broad incumbents

• Fujitsu: Global IT services and SI incumbent with deep Japanese enterprise penetration across manufacturing, financial services, and public sector. Comparable in system integration and core-system modernization offerings but at vastly larger scale.
• NEC: Strategic partner of JmacSoft (JmacSoft is an authorized NEC OA equipment dealer and reseller of NEC EXPLANNER/Ax packages). NEC's broader IT services, system integration, and platform offerings make it a relevant incumbent peer and ecosystem counterpart.
• Hitachi Systems: Japanese IT services arm of the Hitachi group providing system integration, managed services, and consulting to large enterprises. Overlaps with JmacSoft in enterprise SI delivery but operates at much larger scale with broader portfolio.
• NTT Data: Japan's largest system integrator offering end-to-end IT services, consulting, and system integration to global and domestic enterprises. Comparable business model but significantly larger scale and broader geographic footprint than JmacSoft.

Emerging players

• Works Applications: Japanese ERP and cloud business application vendor (AI Works, HUE) targeting large enterprises, competing in adjacent ERP and core-system territory where JmacSoft's ProActive ERP and custom development operate.
• Cybozu: Japanese SaaS provider of groupware and business applications (Kintone, Garoon) for Japanese enterprises. Adjacent peer representing the SaaS-based alternative to traditional SI-delivered business systems that JmacSoft competes against for IT budget share.

Direct peers

• BIPROGY: Japanese SIer (formerly Nihon Unisys) providing system integration, software development, and outsourcing services primarily to Japanese enterprises, including financial and manufacturing customers. Directly comparable to JmacSoft in core enterprise IT services delivery model and customer base.
• SCSK Corporation: Mid-to-large Japanese system integrator serving manufacturing, distribution, and financial enterprises with custom development and IT services. Closely mirrors JmacSoft's SI-led business model, vertical focus, and large-enterprise customer base.
• OBC (Oshō Business Consultants): Japanese software and services company specializing in accounting, payroll, and HR systems for mid-market and enterprise customers. Comparable to JmacSoft's financial-accounting and HR/payroll domain specialization and packaged-software-plus-services model.
• TIS Inc. Japanese IT services company providing system integration, consulting, and outsourcing to financial, manufacturing, and distribution enterprises. Comparable in service mix, target verticals, and enterprise-focused delivery approach.
