What （有）戸田建設 does

いずみ産業株式会社 (Izumi Sangyo Co., Ltd.) is a privately-held Japanese waste management and environmental services company founded in November 1968, headquartered in Utsunomiya City, Tochigi Prefecture. The company operates four integrated divisions from a single site: an Environmental Division handling general and industrial waste collection, transportation, and intermediate treatment (crushing and separation) under multiple regulated waste licenses; a Recycling Division engaged in metal scrap sales/processing and Class 1 fluorocarbon gas recovery; a Demolition Division providing structure demolition and asbestos removal; and a Building Maintenance Division offering cleaning, water tank and drainage cleaning, and mat/mop rental. It holds the only license in Tochigi Prefecture to process fluorescent lamps and has operated as a registered Class 1 fluorocarbon gas recovery operator since April 2006. The company is ISO 14001 certified (since 2021) and maintains membership in the Tochigi Prefecture Industrial Waste Association and Tochigi Prefecture Environmental Beautification Association.

The company serves a horizontal B2B and government customer base within the Kanto region, including construction sites, factories, retail stores/supermarkets, and government buildings. Revenue is generated through service-based fees for waste collection and disposal, professional services fees for demolition, transaction-based pricing for scrap metal purchases, and recurring service contracts for building maintenance. Pricing is uniformly quote-based and not publicly disclosed; scrap metal purchase prices track market rates with variations for shape, composition, and contamination. Go-to-market is sales-led and direct — customers reach the company through phone (028-664-1115) and a contact form on a four-section WordPress website. Distribution is fully direct, with company-owned container trucks, uni trucks, and packer trucks collecting waste on customer sites; there are no resellers or intermediaries. The firm is led by Representative Director Kumamoto Noriaki (熊本範章), has registered capital of ¥20 million (2,000万円), maintains relationships with seven regional banks and two credit unions, and shows no disclosed M&A, funding, or leadership changes in the source material.

Expansion highlights4 records

Broad incumbents

• Obayashi Corporation: Major Japanese general contractor with a demolition and asbestos-removal business. Comparable in demolition and structure dismantling, though as part of a much larger construction portfolio.
• Nishimatsu Construction Co., Ltd. Japanese construction firm with demolition and environmental-remediation services. Comparable demolition and asbestos capabilities to Izumi Sangyo's Demolition Division, though again within a much broader builder.
• Asahi Kasei Corporation: Diversified Japanese chemical and industrial group with environmental solutions including fluorocarbon recovery and recycling. Overlaps with Izumi Sangyo's fluorocarbon and recycling lines, but as part of a global conglomerate.
• Nippon Building Maintenance Co., Ltd. National Japanese building-cleaning and maintenance services company. Comparable to Izumi Sangyo's Building Maintenance Division, but at a multi-region commercial scale.
• Ecore Holdings: Japanese waste-recycling group with collection, intermediate processing, and recycling capabilities. Comparable service mix in waste and recycling, but operates across multiple prefectures with broader customer reach.
• Daiseki Co., Ltd. Japan's largest industrial-waste collection, transport, and recycling company. Directly comparable line of business but at a national, multi-site scale far exceeding Izumi Sangyo's Tochigi footprint.
• JFE Environmental Solutions Corporation: Subsidiary of JFE Steel focused on hazardous and industrial-waste treatment. Overlaps with Izumi Sangyo's industrial-waste and asbestos-related remediation lines, but backed by a major steelmaker.

Regional players

• Tendō Corporation: Japanese construction and demolition firm. Comparable structure-demolition and asbestos-removal services, but operating in a different geography than Izumi Sangyo's Tochigi base.

Others

• Kintetsu World Express (now AP Møller–Mærsk logistics arm in Japan): Adjacent comparator in regulated waste transportation and logistics. Not a direct competitor but illustrates scale players in compliant waste/industrial transport that may eventually encroach on regional haulers.

Direct peers

• Daiei Environment Co., Ltd. Mid-sized Japanese waste-management group offering collection, intermediate treatment, and recycling. Closely aligned in service portfolio to Izumi Sangyo, though at a larger multi-site scale.
