Takemura Seisakusyo

What Takemura Seisakusyo does

Takemura Seisakusyo (株式会社竹村製作所) is a privately held Japanese specialist manufacturer of freeze-proof water supply and water environment equipment, founded in 1947 and headquartered in Nagano City, Nagano Prefecture. The company invented Japan's first freeze-proof valve (TK-type) in 1949 and has maintained an exclusive specialization in cold-climate water infrastructure for over 75 years. Its core products include the signature orange D-type handle series of freeze-proof hydrant columns, water drainage valves, water supply valves, remote control equipment, and meter attachment devices (for Hokkaido), alongside a water environment line covering pool filtration, iron/manganese removal, rainwater utilization, and the emiiR ceramsite water treatment system. Manufacturing is conducted in-house at the Nagano headquarters and the Aqua Zone Mizumi Factory (~59,400 m²) in Iizuna Town, covering the full copper-alloy value chain from casting and machining to assembly and quality inspection.

The company sells primarily through a direct sales network of 10+ branch offices spanning Hokkaido (Sapporo), Tohoku (Aomori, Akita, Morioka, Sendai, Yamagata, Fukushima), and Kanto/Koshinetsu (Kita-Kanto, Niigata, Kofu, Nagano), targeting municipal waterworks departments, construction companies, and public institutions. Secondary channels include a direct-to-consumer e-commerce storefront (tke-shop.shop-pro.jp), exterior-material distributor networks for design faucet columns (entered 2009), and a BtoB platform for electronic invoicing. Customer segments span municipal governments, public institutions (schools, pools, baths), industrial/commercial users (food processing remote monitoring), landscape/exterior contractors, and individual consumers in cold regions. Revenue model is hardware sales across multiple categories with recurring aftermarket parts revenue (inner cylinders, handles, packing) from the large installed base.

From 2023 onward, Takemura has executed an aggressive digital transformation: in-house AI visual inspection for casting defects (>99% accuracy), AI pipe-interior chip detection, BizRobo! RPA for accounting, IoT on the factory floor, and the first domestic implementation of mcframe X cloud ERP (live 2025-08), supported by RPA Technologies, Business Engineering, Kissei Comtec, and Infomart. The company holds Japan Water Supply Association certifications (C-12, C-13), ISO9001 (1999), ISO14001 (2003), METI DX certification (2023), and Security Action two-star, and has accumulated multiple invention awards (Patent Office Director's Award 1997; Good Design 1999; Kanto regional invention awards through 2025). Leadership includes President Katsutoshi Takemura (representative director) and department heads across Technology, Quality Assurance, and branch operations, indicating a family-influenced mid-size Japanese industrial governance model.
