TBK SYSTEM ENGINEERING

What TBK SYSTEM ENGINEERING does

TBK System Engineering Co., Ltd. (株式会社ティービーケー・システムエンジニアリング) is a Japanese systems integrator founded on August 1, 2001, with ¥20,000,000 in founding capital and operating as a subsidiary within the Daiichi Information Systems Group (第一情報システムズグループ). The company designs, develops, and maintains custom enterprise application systems for large Japanese corporations, including manufacturers and equipment-services firms, with 91 employees as of April 1, 2025, working primarily out of its Koriyama (Fukushima) headquarters and a Tokyo office in Shibuya-ku. Its service portfolio is organized around two core lines — Core Business Application System Service (sales, logistics, procurement, production management on Windows/Linux/UNIX using Java, JSF, Struts2, ASP.NET, VB.NET, C#.NET, and PL/SQL) and Test Solution Service (test planning, unit, and integration testing) — supplemented by case-study modules such as an Environmental Comprehensive Information System (Waste Management, Chemical Substance Management, and Environmental Information Sharing modules), a multi-functional enterprise groupware (attendance, scheduler, meeting-room reservation, member directory, memo), and a company-wide Sales Information Sharing System.

The company's products are distinguished by full-lifecycle coverage from requirements definition through maintenance and operations, multi-platform technology breadth, and module-based packages tuned to Japanese regulatory regimes (Waste Treatment Law, Chemical Substances Control/PRTR Law, Energy Conservation Law, Global Warming Countermeasures Law). Case studies document deployments of 35-50 person-months at installations supporting up to 500 users across multiple offices, and long-running maintenance engagements traced back to at least 2009. The company is JIS Q 27001 (ISO/IEC 27001) certified through JIC, signaling enterprise-grade information security management.

TBK generates revenue primarily through professional-services billings on custom development projects and recurring managed-services contracts (maintenance, operations, and help-desk support). Go-to-market is direct enterprise field sales targeting large Japanese corporate clients and government organizations, with engineers deployed on-site at client locations. Pricing is not publicly disclosed; the company does not appear to offer standardized product pricing, instead pricing on a project basis. Disclosed talent-related compensation signals (university graduate starting salary of ¥210,500/month for the 2027 cohort, Tokyo minimum ¥300,000/month, Koriyama minimum ¥230,000/month, plus overtime and twice-yearly bonuses) provide indirect scale anchoring but are not product pricing. Marketing channels are concentrated on its corporate website (tbkse.co.jp) and recruitment platforms such as Mynavi. No public revenue, ARR, or funding figures were disclosed.

Core offering

TBK System Engineering provides custom enterprise application development and maintenance services for Japanese corporates, covering sales, logistics, procurement, and production management systems, plus ERP implementation and test solution services. It also delivers specialized packaged solutions including environmental compliance information systems, multi-functional groupware for large enterprises, and company-wide business information sharing systems, with end-to-end lifecycle support from requirements definition through maintenance and operations.

Product overview

TBK System Engineering offers a unified portfolio of custom-built enterprise systems organized around two core service lines: (1) Core Business Application System Service — spanning sales, logistics, procurement, and production management systems developed on platforms including Windows, Linux, and UNIX using Java/J2EE (.NET stack technologies, PL/SQL), and (2) Test Solution Service — covering test planning, unit testing, and integration testing. These are complemented by three named sub-products from project case studies: the Environmental Comprehensive Information System (a three-module package: Waste Management, Chemical Substance Management, and Environmental Information Sharing systems for environmental compliance), the Multi-functional Groupware for Large Enterprises (featuring attendance/presence management, scheduler, member directory, and memo functions), and the Sales Information Company-wide Sharing System. An AI chatbot for recruitment inquiries is also offered as a product feature. The portfolio is characterized by end-to-end lifecycle coverage (requirements definition, design, development, testing, migration, maintenance/operation) and multi-location/multi-user scalability.
