What Juko does

株式会社寿広 (Juko) is a privately held, family-controlled multi-divisional services conglomerate headquartered in Morioka, Iwate Prefecture, Japan. Founded in 1973 as 盛岡ケミサプライ and reorganized under the current name in 1996, Juko operates three integrated business divisions: (1) Dust Control — rental and cleaning of mats, mops, air purifiers, kitchen filters, and proprietary sanitation products including SEK-certified antibacterial lines and an ozone-based grease trap purification system; (2) Building Maintenance & Security — comprehensive facility management, equipment maintenance, security guard services, and the Juko Line 24-hour emergency reporting system for elderly residents; and (3) Jewel Management — real estate development, brokerage, condominium management (~2,500-2,600 units across 33 buildings), rental property management (~942 units across 40 buildings), and public housing designated management contracts across 8 Iwate municipalities (~5,000+ units). Group subsidiaries include 株式会社サン寿広, 株式会社ダスコムコーポレーション, 銀河環境計画株式会社 (Ginga Environmental Planning, operating two megawatt-scale solar plants), and 株式会社アウトドア寿広 (outdoor hospitality since 2008).

Juko's underlying technology stack blends patented chemistry (FT400 duct antibacterial coating, Patent No. 3865259, co-developed with Fine Technology and Nikkaichi), proprietary sanitation hardware (Jet Perfecter ultra-micro mist system, Daikin co-developed antibacterial pre-filters, ozone grease trap purification), and traditional facility services. Third-party validation is provided by Chiba University Medical Mycology Research Center and Japan Food Research Laboratories. The company earns revenue through a mix of recurring route-based rental/cleaning cycles (2-4 week mat/mop exchanges), long-term facility management contracts, designated government contracts, condominium management fees, and transactional real estate lot sales (11.8M-16.8M yen per residential plot). GTM is enterprise field sales via a 20+ branch network across Iwate, Aomori, Miyagi, and Akita prefectures, supplemented by a Tokyo sales office and channel partnerships with 11+ homebuilders for residential land sales.

The customer base spans municipal governments (8 designated management contracts for public housing and parks), institutional clients (school lunch centers, nursing homes, hospitals, food processors), commercial facilities and hotels, residential property owners, and individual households. Geographic scope is concentrated in the Tohoku region with no disclosed international footprint. The company is led by President Tairo Shinichi (appointed May 2018) with no external PE/VC ownership, no public listing, and no disclosed revenue or headcount figures.
