DUS

What DUS does

DUS (株式会社大運商事 / Daiun Shoji Inc.) is a privately held Japanese IT services and custom system development company headquartered in Osaka. Founded in 1998 as a logistics and freight handling firm, the company pivoted into IT services in February 2001 by establishing its Business Solutions Division and converted to a stock corporation one month later. The company is led by Representative Director Kobayashi Kenji (小林 健史), operates with 15 total personnel (10 full-time plus 5 contract employees), and holds 15 million JPY in registered capital. There are no external institutional investors, no parent company, and no subsidiaries.

The company's core offering is custom system development spanning small-to-large-scale mission-critical business systems, intranet/internet/LAN database environments, and web-based applications. Its technology stack is anchored in legacy enterprise tooling — VB.net, VB, PowerBuilder, Java, PHP against Windows 2003/2000/NT/98 and Linux environments, with Oracle, SQL Server, KeySQL, MySQL, and MDB databases. DUS has productized three semi-packaged solutions: an electronic filing system customizable for embedding into existing systems, a sales and purchasing management system oriented to trading and logistics companies, and a trade show sales support tool. Integration capabilities with SAP R/3 and OBC's Banjac series are positioned as a core technical differentiator. The company supplements custom development with system operation, maintenance, education, and operator dispatch services.

DUS generates revenue through project-based professional services engagements, one-time software and hardware sales, managed maintenance contracts, and operator dispatch. It targets manufacturing, warehousing and logistics, distribution and retail, government/public sector, and financial institutions verticals in the Kansai region. Named clients include ORIX Corporation, Mitsubishi UFJ Lease & Finance, Kinki Sogo Lease, Matsuo Corporation, Wak Sangyo Corporation, Toho Kogyo, Osaka City Sports and Green Promotion Association, and Osaka City Education Promotion Corporation. GTM is direct sales-led: inbound inquiries via the dus.co.jp website, phone (06-4800-6718), and email ([email protected]) convert to consulting engagements that lead to system development and implementation projects. The company maintains technology partnerships with NEC Fielding, Sanwa Computer, ITEC Hankyu Hanshin, SoftBank Telecom, Daiwabo Information System, OBC Business Consultant, Promate, NTT Data, and NTT PC Communications.
