Tokai Kankyo

What Tokai Kankyo does

Tokai Kankyo Corporation (東海環境株式会社) is a privately held Japanese industrial waste management and demolition contractor, founded on March 25, 2008 by Representative Director Nakajima Kiyotomo and headquartered in Yao City, Osaka Prefecture. The company operates two divisions: an Industrial Waste Division (産廃事業部) that collects, transports, and intermediate-processes construction, demolition, and soil-contaminated mixed waste, and a Demolition Division (解体事業部) that delivers end-to-end building demolition from permitting and notification through certified waste disposal. As of November 2025 the company employs 101 people and operates from three sites — its headquarters/Head Office Factory in Yao City, the Sand Clean facility in Matsubara City, and the Yokubari Factory in Yao City — with a fully owned fleet comprising 2t/4t/10t container trucks, container full trailers, dump and van semi-trailers, tractors, and excavators/loaders (PC30 through PC210 plus WA100/WA200 and HB215).

The company's technical differentiator is Sand Clean, established in January 2016 and described as Osaka's first mixed-waste washing plant. Rather than operating purely as an intermediate processor, Sand Clean functions as a manufacturing-style facility that washes and classifies soil-contaminated managed mixed waste into recycled sand, with a sorting and crushing processing capacity of 240 cubic meters per day. This allows the company to internalize recycling, reduce landfill volumes, and capture a higher-value output than typical waste haulers. Revenue is generated primarily through transactional service fees on collection/transport volumes and disposal/intermediate-treatment processing, supplemented by project-based demolition fees, with publicly disclosed demolition project values ranging from approximately ¥1.1 million to ¥4 million. The customer base is B2B and concentrated in construction companies, demolition contractors, and general contractors, accessed via a sales-led motion through the company's website contact form and direct phone inquiries.

The go-to-market is regionally anchored in Kansai (Osaka, Hyogo, Kyoto, Nara, Shiga, Wakayama) but extends nationally through industrial waste collection and transportation permits held across 24 prefectures spanning Kanto, Chubu, Kansai, Chugoku, Shikoku, and Kyushu, including special controlled waste (特管) permits in 13 prefectures. The company holds ISO 9001 and ISO 14001 certifications under an integrated Quality-Environment Management System, banking relationships with Resona Bank, Sumitomo Mitsui Banking Corporation, and Kiyo Bank, and ¥20 million in registered capital. There is no disclosed external funding, M&A activity, partnership, or app/digital platform.
