What Software Agency does

Software Agency (株式会社ソフトウェアエージェンシー) is a Tokyo-based private IT services firm founded in September 1990 by President Miyahara Masaru. The company designs, develops, and maintains business information systems for Japanese enterprises, with a documented focus spanning IBM mainframe (COBOL, PL/I), AS/400/IBMi (RPG), and modern open-system stacks (Java, VB.net, PHP, Oracle, SQL Server, MySQL). Its service portfolio is organized into four lines — Application Services (consulting, process redesign, system design/development, web applications), Network Services (LAN/intranet/groupware construction and operations), Database Services (design and operations support), and System Introduction & Operations Support — supplemented by specialized AS/400/IBMi lifecycle services (RPG development, RPG-to-modern conversion, DB2-to-Oracle migration) and VBA/Excel/Access development.

The company's go-to-market is sales-led, B2B, and field-based, operating two engagement models: dispatched engineer staffing (労働者派遣, license 派13-306460) and contract development (業務委託). For dispatch, the firm discloses an average daily fee of ¥43,412 and a 36.0% margin rate per Japanese regulatory requirements. The firm holds a Privacy Mark certification (No. 21000891) and serves a verticalized mix of finance, trading, manufacturing, real-estate information, auto-leasing, cosmetics, apparel, consumer goods, pharmaceutical, food, and construction clients. Named customer references include SCSK, 三菱総研DCS, アイエヌジーン, 日本ベッド製造, フロンテック, ソリッドシード, and ドリームカーゴシステム.

Commercially, Software Agency operates on a project- and time-based professional services revenue model with no productized software, no disclosed recurring subscription revenue, no outside investors, and no M&A activity. Distribution is single-country (Japan, primarily Kanto) and channel-limited — direct inquiry via corporate website, industry-association networking, and dispatch-subcontractor relationships with larger IT services firms. The company is founder-controlled (President Miyahara Masaru also serves as personal-information protection manager), with no publicly disclosed revenue, no funding rounds, and no parent or subsidiary entities.
