What Ryokusan Co. does

Ryokusan Co., Ltd. (緑産株式会社) is a privately held Japanese industrial machinery manufacturer founded in 1969 and headquartered in Sagamihara, Kanagawa Prefecture. The company specializes in biological resource circulation technology and supplies specialized equipment across three integrated verticals: wood biomass energy, environmental recycling, and agricultural and dairy farming. Its product portfolio includes wood shredders (REX-One, Wood Hacker Mega, Axtor, Crambo, Terminator), separation and sorting machines (Multistar, Top Screen, Stonefex, Ballistor), compost turners (Topturn, Compturn), biomass boilers (Herz), forestry machinery (Falcon tower yarder), irrigation systems (Rainstar, Smart Rain), slurry handling equipment (Slurry Mixer, Slurry Pump, Presstar separator, BBP bedding processor), TMR mixers, and European-built agricultural tractors and telehandlers distributed under agency arrangements.

The company's revenue model is built on one-time sales of industrial machinery to enterprise customers including dairy farms, forestry operations, waste processing facilities, and biomass power plants, supplemented by aftermarket parts and service revenue through its Parts Center and Customer Center. In June 2026 it launched RGUM, a certified pre-owned machinery program, extending its revenue surface into the secondary equipment market. Go-to-market is predominantly direct sales via phone-based department routing and web inquiry forms, reinforced by an event-driven channel strategy that includes the NEW Environment Expo, the Global Warming Prevention Expo, regional LMJ-RYOKUSAN fairs, forestry machinery demonstrations, and the International Livestock Expo 2027. Operations are concentrated in Japan with export activity into Southeast Asia, notably Thailand and Vietnam, through distribution partners. The company is privately held with no disclosed parent, investors, or funding rounds, and has operated continuously for over 55 years under its founding mission of environmental society-building through biological resource recycling.

Direct peers

• Vermeer Corporation: U.S. manufacturer of forestry, biomass, and agricultural equipment including chippers and tub grinders. Comparable to Ryokusan's biomass-shredding and forestry product categories (e.g., Falcon tower yarder) and similar diversified farm/forestry customer base.
• Morbark LLC: North American manufacturer of wood chippers, grinders, and biomass-handling equipment. Comparable as a specialist in industrial wood/biomass shredding machinery serving forestry and biomass-power-plant customers analogous to Ryokusan's shredder and chip-production line.
• Jenz GmbH Maschinenbau: German specialist in mobile biomass chippers and shredders. One of the key OEMs behind Ryokusan's biomass processor line, and directly comparable in product category, customer profile (forestry contractors, biomass plants), and geography of focus.
• CLAAS KGaA: German global harvester and tractor manufacturer whose machinery (Crambo, Terminator, Axtor shredders; tractors) is distributed by Ryokusan. Directly comparable product portfolio in shredders, tractors, and biomass handling, and a key OEM-counterparty to Ryokusan.
• Komptech Group (Komptech GmbH): Austrian/European manufacturer of shredders, screens, and composting turners — a direct upstream supplier of equipment Ryokusan distributes (Topturn, Multistar). Closely aligned in product technology and end markets (waste, biomass, composting).
• Mitsubishi Mahindra Agricultural Machinery: Japan-based joint venture producing tractors, combines, and rice transplanters. Shares Ryokusan's Japanese farm-equipment distribution model and target customer segment (commercial farmers and contractors), with similar exposure to Japan's shrinking farmer demographics.

Broad incumbents

• Yanmar Holdings: Major Japanese manufacturer of agricultural engines, tractors, and biomass energy systems. Competes with Ryokusan in dairy/livestock equipment, biomass cogeneration, and irrigation, and represents a much larger incumbent with global reach.
• Kubota Corporation: Japan's largest agricultural machinery manufacturer, offering tractors, implements, and increasingly IoT/smart-farming systems. Overlaps directly with Ryokusan's tractor distribution and broader farm-equipment customer base in Japan, and sets the competitive benchmark for scale and dealer network.
• IHI Corporation: Large Japanese heavy industrial conglomerate with agricultural, biomass, and environmental equipment lines. Comparable as a broad incumbent with overlapping exposure to biomass energy, composting, and resource-recovery infrastructure projects in Japan.

Regional players

• Takeuchi Mfg. Co., Ltd. Japanese manufacturer of compact track loaders, excavators, and carriers. Comparable as a Japan-based niche industrial-machinery specialist serving construction, agriculture, and forestry contractors — a similar customer base to Ryokusan's Scorpion telehandler and tractor buyers.
