Mikuni

What Mikuni does

Mikuni Co., Ltd. (株式会社三国) is a privately held Japanese diversified industrial services group headquartered in Sakai City, Fukui Prefecture, founded in March 1962 (originally as Mikuni Kairiku Kogyo Kabushiki Kaisha). The company operates four core business divisions: Logistics, providing mid- and long-distance fuel and freight transport with a fleet of 90+ vehicles including dedicated petroleum tank lorries, trailers, wing trucks, and chemical tankers; Construction, holding 13 Fukui Prefecture construction licenses covering civil, electrical, plumbing, mechanical, steel structure, and demolition work for infrastructure maintenance at oil storage facilities and power plants; Maritime/Disaster Prevention, operating the 237-ton Ganryu disaster prevention vessel, tugboats, port cargo handling, ship agency services, and contracted oil spill response at Fukui Port under agreement with the Japan Ocean Disaster Prevention Center; and Contract Services, providing on-site labor dispatch to industrial facilities including a long-standing in-plant contract at UACJ Fukui Manufacturing at Technoport Fukui. The company also controls a six-member subsidiary group spanning industrial machinery, automation systems, electrical contracting, automotive sales, and food service.

Mikuni's revenue model is contract-based B2B services delivery with no publicly disclosed pricing. Revenue streams span per-transaction freight fees, per-project construction billing, managed maritime services, and professional services for labor dispatch — collectively addressing oil majors, industrial manufacturers, infrastructure operators, port authorities, and government bodies. G-Mark safety certification (held continuously since January 2005), Green Management certification (since March 2006), and the 2025 zero-accident record serve as core B2B trust signals. The company has 220 employees at the parent level and operates a regional Kansai sales office in Uji City, Kyoto, in addition to a maritime department office and an in-plant office at UACJ. Recent strategic activity has centered on workforce certification (Workplace-Friendly one-star in 2025, Health Management Excellence in 2026), recruitment-focused digital channels (YouTube, Instagram, Facebook, dedicated recruitment portal), and ESG positioning aligned with UN SDGs.
