ワークスワークス Company Profile

For custom-made outdoor toilets and unit houses, choose Prime Made.

Until now, we have been selecting the outdoor toilets and unit houses that are closest to our customers' wishes from ready-made products. However, with our brand's completely custom-made Prime Made, you can be free from all constraints regarding size, functionality, materials, colors, and equipment, allowing you to combine them freely to suit the installation location and surrounding environment. Prime Made, which manufactures unit houses completely custom-made, is the only brand in Japan that has obtained ISO 9001 certification.
