Koshin Co.

What Koshin Co. does

Koshin Co. (株式会社工進, Koshin Ltd.) is a Japanese specialty industrial and consumer equipment manufacturer founded in 1948 and headquartered in Nagaokakyo City, Kyoto Prefecture. The company designs, manufactures, and distributes a broad portfolio of pumps — engine-driven, electric, submersible, oil, chemical solvent, kerosene, marine, and bilge pumps — alongside complementary outdoor power equipment including grass mowers, sprayers, snow blowers, cultivators, generators, pressure washers, and garden tools. Its flagship platform is the Smart Koshin series, an 18V/36V interchangeable lithium-ion battery ecosystem spanning lawn mowers, hedge trimmers, sprayers, blowers, and chainsaws, which surpassed 1 million cumulative units sold by June 2026. The company also markets a hybrid energy storage system that combines traditional generators with battery technology, signaling entry into adjacent portable power markets.

Koshin operates three in-house domestic factories (built in 2008, 2014, and 2022) and a manufacturing facility in Ningbo, China, supporting vertical integration across mold-making, resin molding, and metal welding. Products are sold in approximately 160 countries through international distributors, and domestically through a layered channel network that includes KBPS (Koshin Business Partner Shops) authorized dealers, home center chains (DCM, Sunday, Komeri, Cainz), JA agricultural cooperatives, agricultural equipment retailers, and specialized snow blower service shops. Pricing is predominantly open (set by individual dealers) with selected battery SKUs carrying listed retail prices. The company employs 262 people in total, with average tenure of 13.7 years, and is privately held with an 87.9% equity ratio (FY2024) and ¥16.5 billion in net sales.

The business model is hardware product sales through dealer-mediated channels to fragmented end markets including agriculture, civil engineering and construction, industrial fluid handling, marine/ship, and consumer/home use. No public listing, external funding rounds, M&A activity, or AI/ML capabilities are disclosed. Customer concentration is low given the breadth of the dealer network and absence of named enterprise contracts. The senior leadership team is led by President and CEO Eiichi Oohara, who also serves as Chairman, consistent with founder/family ownership and a conservative, debt-light capital structure.

Direct peers

• Tsurumi Manufacturing Co., Ltd. Japanese submersible pump manufacturer serving industrial, construction, and agricultural applications globally. Most direct pump-manufacturing peer; overlaps with Koshin in submersible water pumps and contractor-focused distribution.
• Makita Corporation: Japan-headquartered manufacturer of professional cordless power tools and outdoor equipment using 18V/36V LXT battery platforms. Direct competitor to the Smart Koshin battery ecosystem across grass cutters, blowers, and sprayers.
• Kubota Corporation: Japanese agricultural and construction machinery manufacturer including small pumps, generators, and outdoor equipment. Comparable go-to-market in Japan through JA cooperatives and dealer networks and similar depth of cultivator/tiller expertise.

Broad incumbents

• Honda Power Equipment: Division of Honda producing portable generators, pumps, snow blowers, and engines. Overlaps with Koshin's engine pumps, generators, and outdoor power equipment categories from a much larger global automotive/equipment brand.
• Ebara Corporation: Japanese industrial pump, compressor, and turbomachinery manufacturer. Comparable pump-manufacturing heritage and Japanese engineering scale, although Ebara skews to much larger municipal/industrial process pumps.
• Pentair plc: U.S. water solutions company spanning residential, commercial, and industrial pumps and water treatment. Overlaps with Koshin's water-handling pumps and broader fluid-transfer value proposition, though at significantly larger scale and different channel mix.
• Briggs & Stratton: U.S.-based small engine and outdoor power equipment manufacturer (now under KPS Capital ownership). Comparable engines and outdoor equipment competitor relevant to Koshin's engine-pump and grass cutter businesses.
• Yamaha Motor Co., Ltd. Japanese manufacturer whose outdoor power equipment segment covers generators, pumps, snow blowers, and multipurpose engines. Direct overlap with multiple Koshin product lines including marine products via outboard motors.
