What Tesco does

TESCO Co., Ltd. (テスコ株式会社) is a privately held Japanese environmental services and facility management company founded in 1967 and incorporated in 1970 as Taiei Engineering, renamed to TESCO in January 2003. Headquartered in Chiyoda-ku, Tokyo, the company operates six interconnected service divisions: waste treatment facility O&M (incineration, recycling, non-combustible processing, final disposal), water treatment facility O&M (purification, sewage, human waste, agricultural community sewage, pumping stations), comprehensive building maintenance (facility operations, cleaning, security, hotel management), plant engineering/construction/consulting (new construction, overhauls, PFI projects), overseas environmental business across Thailand, Malaysia, Myanmar, and Vietnam (industrial estate wastewater treatment, reclaimed water supply, waste incineration O&M), and an engineering business providing hardware/software design, factory-shipment testing, and quality inspection for elevator and power system manufacturers. Supporting sub-businesses include a high-precision 3D printing center (D&A Technology Center) and staffing dispatch operations in Hakodate and Nagano.

The company runs a 150+ location nationwide network covering 11 branches and 14 sales offices, manages 100+ environmental facilities and approximately 50 building sites, and employs 3,306 people as of August 2025. Technology assets include a proprietary TESCO sliding-type stoker for waste incineration, AI-powered remote centralized monitoring and automatic control systems for treatment plants, ozone-based advanced water treatment for micro-pollutants, and high-precision 3D printing at 16-micron pitch resolution. The company holds ISO 9001/14001/27001, Privacy Mark, and a dense stack of specialized Japanese business licenses and registrations (security, worker dispatch, fee-charging employment agency, specified construction, building sanitation management, etc.).

Revenue is generated primarily through long-term managed services contracts with municipal governments (comprehensive commissioning, third-party commissioning, PFI arrangements), project-based construction and consulting work, recurring building management and hotel management fees for private property owners, professional services and personnel dispatch for elevator/power-system manufacturers, and overseas managed-services contracts (e.g., 11,000 tons/day industrial wastewater treatment per site in Thailand, 7,000-9,000 tons/day reclaimed water supply). Pricing is not publicly disclosed. The company uses a direct B2B sales-led go-to-market model leveraging its branch network, ISO certifications, and industry association memberships, with new graduate starting salaries disclosed at ¥211,500-216,500/month base. Registered capital is ¥196 million.
