Who Founded Sohgo Security Services Co.?
Founders and Early Ownership of Sohgo Security Services centered on Junshiki Murai, a former National Police Agency official who founded the company in July 1965 and maintained near-total private control through family holdings and allied executives.
Founder background
Junshiki Murai leveraged police experience and administrative networks to shape the company’s operational ethos and initial equity structure.
Initial ownership
At founding in July 1965 ownership was almost entirely private, with Murai and a small circle of associates holding the majority of shares.
Family consolidation
Equity was consolidated within the Murai family and Sohgo Corporation, an asset entity created to centralize family interests and voting control.
Funding sources
Early growth was funded through retained earnings and debt from major Japanese banks rather than public venture capital rounds.
Protective agreements

The concentrated ownership prioritized long-term continuity; the Murai family effectively controlled 100 percent of voting rights in the early decades.
Family-controlled equity and bank financing enabled stable expansion, securing major public and private contracts and allowing the firm to navigate economic cycles of the 1970s–1980s while preserving its public-service-oriented mission.
