Lightware

What Lightware does

Lightware Co., Ltd. (株式会社ライトウェア) is a privately held Japanese software development and IT staffing firm founded in September 1990 by President Hirano Senji (平野線治) and headquartered in Toshima-ku, Tokyo. The company operates two principal lines of business: (1) commissioned development (一括請負開発) — full-cycle custom web application projects spanning requirements definition through testing and maintenance — and (2) system engineering services (SES / 技術者派遣) — on-site engineer dispatch under labor dispatch permit 派13-307652, with a current roster of 24 dispatched engineers at 6 client sites and a disclosed 33.6% margin on a 32,092 JPY day rate. Since 2021 the firm has additionally operated a fee-based employment placement business (permit 13-ユ-312925), and it runs two consumer-facing digital properties: Light Staff (ライトスタッフ), a freelance IT engineer placement platform, and Saku Career (咲くキャリ情報局), an IT engineer information portal.

The technical foundation is Java- and ColdFusion-centric and reflects long-tenured, legacy-era specialization rather than modern cloud-native stacks. Core frameworks include Seasar2 with the proprietary S2Flex2 rich-client extension, Apache Struts, and Adobe Flex, paired with Oracle, PostgreSQL, SQL Server, and DB2 databases, and integration with WebLogic, Intra-Mart, BIRT, and Monaca (HTML5 hybrid). The company has codified an internal Seasar2 development standardization manual and supports Oracle Master certification for engineers. Compliance posture is unusually strong for a 49-person firm: ISO/IEC 27001 (IS 641953, 2015), ISO 9001 (2017), Privacy Mark (2006), and the dispatch and placement licenses noted above. The customer base is diverse by industry — case studies span cosmetics e-commerce, paper manufacturing, broadcasting, trading, semiconductor, beverage, apparel, government, automotive, insurance, aviation, entertainment, brewery, electric power, and elderly care — with over 90% of projects delivered as long-term team-based engagements and roughly 60% of dispatched engineers working under remote or hybrid arrangements.

FY2024 revenue is 4.3 billion JPY, up from initial 5-million-yen paid-in capital at founding, and the firm has grown entirely through retained earnings with no external investors, no parent company, and no disclosed M&A. Workforce metrics underscore a stable, mature operating profile: 9-year average employee tenure, 33-year average engineering age, 55% telework adoption, 11.5 hours average monthly overtime, and 13 days average paid vacation. Geographic focus remains the Tokyo metropolitan area, with affiliate ties to major Japanese system integrators (NSSOL, Hitachi Systems, Fujitsu) and technology partners (Adobe, Oracle, Red Hat, Seasar Project, Monaca).
