System Development

What System Development does

System Development Corp. (株式会社システム・ディベロップメント) is a privately held Japanese IT services company founded in July 1997 and headquartered in Shibuya-ku, Tokyo. It operates as a wholly-owned subsidiary of Uni Information Co., Ltd. (ユニ・インフォーメーション株式会社), which has held 100% of shares since incorporation. The firm maintains 11-50 employees and registered capital of ¥10 million, with no public listing, external funding rounds, or disclosed subsidiaries.

The company delivers a portfolio of traditional IT services rather than a unified product platform. Its core offerings include computer business consulting, system proposal and design, custom software development, and communication software design and development. It additionally operates a licensed worker dispatch business (派13-309131) supplying IT engineers — primarily System Engineers (SEs) — to client organizations. The work locations are limited to the Tokyo metropolitan area (Kanto Region), and the only named major client is ITOCHU Techno-Solutions Corporation, a large Japanese IT solutions provider.

System Development generates revenue through professional service engagements and labor dispatch contracts, with pricing not publicly disclosed and compensation structured around employee experience and skills. Its go-to-market is direct enterprise engagement with no formal distribution partners, resellers, or digital marketing channels beyond a simple corporate website. No AI/ML capabilities, proprietary technology platform, patents, or external funding are documented. Banking is conducted through MUFG Bank's Shibuya branch.
