What WAKO does

WAKO Group is a privately held Japanese integrated systems company headquartered in Matsue, Shimane Prefecture, with operating roots dating to 1917. The group is structured under WAKO Holdings (和幸ホールディングス), established July 1, 2024, and operates through four wholly-owned subsidiaries: WAKO Co. (marine and land communications, environmental systems), WAKO Reion Co. (HVAC, refrigeration, sanitation, fire prevention), WAKO Dentsu Co. (electrical telecommunications, fire defense, AV/stage lighting, TV/nurse call systems), and WAKO Information System Co. (IT solutions including system development, network construction, and security design). The group employs approximately 230 people as of 2025.

The company serves regional enterprise and government clients in Shimane Prefecture and western Japan through direct field sales via its specialized subsidiaries. Its underlying technology is integrated systems engineering rather than a single platform: each subsidiary operates as a domain-specialized systems integrator that designs, installs, and maintains physical infrastructure (HVAC, fire suppression, telecommunications cabling, marine radio) and IT infrastructure (custom software, LAN/WAN, security). Notable technical capabilities include ISO 27001-certified IT security services (WAKO Information System, 2020), ISO 9001 quality management (WAKO Dentsu, 2004), and Privacy Mark certification (2021). The group does not develop proprietary software products; instead, it delivers engineering services, equipment installation, and maintenance contracts.

WAKO generates revenue through project-based systems integration, equipment installation, and ongoing maintenance and IT service contracts. Pricing is not publicly disclosed and is handled via B2B quotations typical of regional Japanese systems integrators. Distribution is entirely direct through subsidiary-level client relationships. The group is family-led (Yamashita family, founded by 山下平三郎), with 山下 剛史 serving as representative director. The holding-company structure established in 2024 is intended to centralize group strategy while preserving subsidiary specialization.
