SUNTECH

What SUNTECH does

SUNTECH Co., Ltd. (サンテック株式会社) is a privately held Japanese IT services company founded on August 1, 1984 in Sakai City, Osaka, and currently headquartered in Chuo-ku, Osaka. The company specializes in IT system implementation, ERP package deployment, and operations and maintenance services for enterprise customers, with a concentrated focus on the manufacturing industry. Its core technology stack centers on the IBM Power i (formerly AS/400) platform, with primary development in RPG/ILE RPG, supplemented by Java, Visual Basic, COBOL, and C/C++, and database coverage spanning DB2, Oracle, and SQL Server. The company also developed proprietary manufacturing-oriented production management software — originally FMS/36 (released 1986) and later the integrated FMS package (completed 2006) — and integrates with intra-mart middleware, Data Spider, Dr Sum, and JoyScheduler as part of broader system solutions.

SUNTECH operates a three-pillar service model: (1) custom IT system development from scratch on IBM Power i platforms; (2) third-party ERP implementation covering Oracle JD Edwards, mcframe, Infor XA, and SAP Business One; and (3) ongoing operations and maintenance support delivered through standardized service processes, remote VPN-based servicing, and a dedicated customer web support portal. Revenue is generated through professional services engagements (IT consulting, business innovation consulting, system analysis/design/development/testing) and managed services (ongoing maintenance and support), with all pricing handled through direct sales inquiry rather than public disclosure. The company maintains Application Partner status with Oracle Japan (since August 2007), Engineering Partner status with Business Engineering Corporation for mcframe (since April 2017), and business partner relationships with IBM and Infor, and co-founded Solution Lab Kansai with IBM Japan in 1991.

The company serves Japanese manufacturing enterprises across at least ten disclosed sub-sectors — including aerospace engine, automotive, automotive parts, precision machinery, measuring instruments, electronics, stationery, processed food, aviation equipment, and industrial waste processing — and also addresses distribution/trading companies and existing IBM Power i users seeking maintenance or modernization. SUNTECH is led by Representative Director Nakai Masatoshi (中井雅俊), operates from a single Osaka headquarters, and most recently obtained a worker dispatch business license in June 2025, signaling intent to add IT staffing services. The firm holds a Privacy Mark certification (since September 2006) and operates as a traditional founder/management-controlled private corporation with no disclosed external institutional investment, public listing, or material M&A activity.

SUNTECH provides IT consulting, custom IT system implementation, ERP package implementation, and ongoing operations and maintenance services to manufacturing-sector enterprises in Japan. The company specializes in IBM Power i (AS/400) environments using RPG/ILE RPG and supports rollouts of Oracle JD Edwards, mcframe, Infor XA, and SAP Business One. It also sells computer-related hardware and software and dispatches IT engineers under its worker-dispatch license.

Direct peers

• Future Corporation: Japanese independent IT consulting firm (TYO:4722) that supports manufacturers on ERP, production, and digital transformation projects. Comparable to SUNTECH in its manufacturing-vertical focus and ERP implementation services for mid-market Japanese industrial customers.
• NS Solutions Corporation: Japanese systems integrator (TYO:2327) affiliated with Nippon Steel that provides IT solutions to industrial and manufacturing clients including ERP and production management systems. Direct comparable in vertical specialization on manufacturing IT.

Broad incumbents

• IBM Japan: Japanese arm of IBM and a key SUNTECH business partner for IBM Power i (AS/400) platforms. IBM Japan's hardware roadmap and partner ecosystem directly affect the long-term viability of SUNTECH's AS/400-centric services.
• Nihon Unisys: Established Japanese IT services firm (TYO:8056) delivering system integration, cloud, and managed services to enterprises including manufacturers. Provides a similar mix of consulting, implementation, and operations services that competes with SUNTECH in the Japanese enterprise market.
• SCSK Corporation: Major Japanese systems integrator (TYO:9719) within the Sumitomo group, offering ERP, IT outsourcing, and manufacturing industry solutions. Overlaps with SUNTECH in ERP implementation and managed services for Japanese manufacturers but operates at a much larger scale and breadth.
• Oracle Japan: Japanese subsidiary of Oracle and SUNTECH's Application Partner since 2007 for JD Edwards implementations. As the underlying ERP vendor, Oracle Japan's ecosystem strategy and partner program directly shape SUNTECH's JDE-related project pipeline.
• Infor Japan: Japanese subsidiary of Infor and SUNTECH's listed business partner for Infor XA (formerly Mapics) ERP implementations. As the vendor of a manufacturing ERP line SUNTECH resells and implements, Infor Japan is both a partner and an indirect ecosystem participant.
• NTT Data Group: Largest Japanese SI group (TYO:9613) with a deep manufacturing ERP and SAP/Oracle implementation practice. Competes with SUNTECH for large enterprise transformation deals, though at significantly larger scale and a global delivery footprint.
• TIS Inc. Major Japanese IT services company (TYO:3626) providing consulting, system integration, and outsourcing including manufacturing ERP. Comparable as a domestic SI competitor chasing the same manufacturing ERP wallet share as SUNTECH.

Emerging players

• Business Engineering Corporation: Developer of the mcframe manufacturing-focused ERP package and SUNTECH's formal Engineering Partner since 2017. Comparable as a manufacturer-focused ERP provider, with SUNTECH acting as one of its implementation partners.
