What COSMOS COMPUTER SYSTEMS does

COSMOS COMPUTER SYSTEMS (株式会社コスモスコンピュータシステムズ) is a privately held Japanese software developer incorporated on February 2, 1991, headquartered in Chigasaki, Kanagawa Prefecture, with registered capital of ¥10,000,000 and a headcount of 1-10 employees. The company develops and sells Windows-based desktop business software targeting three narrow, regulated Japanese verticals: licensed explosives dealers, licensed firearms dealers, and real estate companies. Its core products are the Explosives Sales Management System (¥600,000 perpetual license) and its SP Business Version (¥800,000), the Firearms Inventory Management System (¥600,000), and a real estate suite comprising the Rental Property Management System and the Real Estate Contract Document System, which together automate 重要事項説明書, rental/sales agreements, and transaction ledgers per Japanese legal formats. All software is built as Windows desktop applications supporting Windows 10/8/7.

The company operates a direct-to-customer sales model through its website (cosmos-computer.com) and contact form, with customers primarily in the Kanto region. Revenue is generated from one-time perpetual software licenses, optional paid customization services, separate paid maintenance contracts, and a recurring monthly website management service priced at ¥15,000/month under a ¥100,000 initial setup fee. Listed major counterparties include NEC Networks & System Integration Corporation and NTT Communications Corporation. The company is led by Representative Director Kaji Toshihito (加地 敏仁), who has held the role since founding. Its banking relationships are with Bank of Yokohama (Yokohama Ekimae branch) and Mizuho Bank (Hamamatsucho branch). There is no evidence of external investors, subsidiaries, or capital-raising activity.

Business operations appear stable and maintenance-oriented rather than expansionary: the company has released Windows 10-compatible updates and added the SP Business Version module but has not pursued new geographies, new verticals beyond its existing regulated niches, or material product investment. The overall profile is that of a long-tenured niche micro-ISV serving a shrinking pool of licensed Japanese dealers and small-to-mid real estate operators.
