Yoshihara Kakou Co., Ltd.
We manufacture underdrainage materials that excel in pressure capacity, permeability, water catchment, and drainage.
Our company manufactures plastic products through extrusion molding and injection molding. Our underdrainage material for civil engineering has a unique three-dimensional spiral structure that has excellent water catchment, drainage, and pressure functions. This combination of a high pressure capacity with 90% porosity permeability eliminates the intrinsic negative factors such as humidity and mites.
[Company strength] Our company can respond to various customer needs by manufacturing a wide range of products with the extrusion molding and injection molding facilities we possess. Our underdrainage material has a unique structure that can be used for applications other than civil engineering. Our injection molding facilities operate 24 hours a day, and can accommodate requests for large-lot production. [Business description] Our company manufactures and sells plastic products produced using extrusion molding and injection molding. We use extrusion molding to manufacture underdrainage materials for civil engineering, and supply more than 90% of them to public works projects. We use injection molding to manufacture a wide range of products from auto parts to general consumer products. [Industry] Plastic product manufacturing [Strength of products/technologies] Our main product, which is our underdrainage material, is our original product. We patented the technology, and sell the product as the only such product available in Japan. This product has a three-dimensional net-like structure, but it differs greatly from other commonly available three-dimensional net-like structures in its internal parts. Multiple spiral-shaped hollow cylinders are aligned inside it. This structure dramatically enhances the product’s functionality as a water catching and draining material (water catchment, drainage, and pressure functions), which has already been highly evaluated. This structure can be applied to uses other than civil engineering, so we are gradually receiving inquiries from other fields. [Representative's message] Civil engineering is the major application of our three-dimensional net-like spiral structure, but we are developing other applications at the same time. This is why we believe that it is important to enhance recognition of this unique structure in other fields. We intend to start overseas expansion mainly centering on North America and Canada. We also hope to introduce this product on our company website. [Company structure for market development/overseas expansion] We continue to do business with major companies without showing any problem in our response. Inquiries from overseas companies are responded to by employees with the necessary language ablity. [Market share/Ranking] We have acquired a 30% share of the domestic Japanese backside drainage material market (the material is used in tunnels). [Awards and media coverage] [Awards] [Media] [Authorization/Certification] Ministry of Land, Infrastructure, Transport and Tourism (NETIS). Japan Environment Association (Eco Mark). Better Living (Moyai Drain Wall). Aichi Prefecture (Aicle). [Joint research and development] Obihiro University of Agriculture and Veterinary Medicine (joint research on soil erosion prevention method in cold regions); Kitami Institute of Technology (countermeasures against frost heaving). [Main Clients / Business History (domestic)] Ohbayashi, Kajima, Taisei, Shimizu Construction, and other general contractors (purchasers of our underdrainage material, since 1998).
