What Nihon Kasetsu does

Nihon Kasetsu (日本仮設株式会社) is a privately held Japanese company founded in 1967 and headquartered in Sapporo, Hokkaido, that develops, manufactures, sells, and rents temporary construction materials, systems, and related safety and environmental equipment. The company operates an integrated three-pillar model combining trading (商社), manufacturing (メーカー), and rental (レンタル) functions, supported by direct sales account managers, a Tokyo branch, six Hokkaido sales offices (Hakodate, Tomakomai, Asahikawa, Kushiro, Kitami, Obihiro), a European subsidiary in Zaragoza, Spain, and a proprietary B2B e-commerce storefront (カセツドア). Its portfolio covers over 100,000 products and methods spanning formwork, scaffolding, temporary access, all-weather roofing, concrete quality management, water treatment, vibration reduction, monitoring/ICT, and disaster prevention, with original brands such as KB Joint, Geopad, Patchin-Ieye, Zero System, MT Series, and Bond Terra Method, many of which carry NETIS registrations and patents.

The company earns revenue through four streams: one-time equipment and materials sales (including via the e-commerce platform), recurring equipment rental (scaffolding, formwork, monitoring systems, snow melting, water treatment units), professional engineering and consulting services (仮設設計, manufacturing technology, concrete consulting with 30+ years of expertise), and digital sales of proprietary and standard products. Customers are primarily civil and building construction contractors in Hokkaido and eastern Japan, supplemented by Hokkaido agricultural and dairy farming operations (water treatment, animal welfare, snow management) and public sector clients whose projects often require NETIS-registered technologies and compliance with JASS5 and public construction standards. The company is privately owned, has 101-250 employees, is led by Representative Director Kikuhara Ayumu (菊原歩), and marked its 60th anniversary in 2027 with a stated goal of becoming a 100-year enterprise.
