Kyoritsu Sangyo Co., Ltd. is engaged in the manufacturing and sales of artificial marble (reconstituted stone) and FRP molded products. Since its establishment, we have primarily focused on major housing equipment manufacturers, producing and processing artificial marble washbasins, wash counters, toilet counters, kitchen counters, and FRP drains. As an overseas base, we have established a local corporation in Cebu, Philippines, where we produce artificial marble (reconstituted stone) and export it in containers to Japan, managing inventory domestically to ensure timely delivery. We mainly use polyester resin as the material for artificial marble (reconstituted stone). We are also capable of manufacturing FRP (fiber-reinforced plastic). We manufacture and sell OEM products for companies such as Panasonic and Cleanup, and since 2022, we have been working on the development of our own products (washbasins). *For more details, please download the PDF or contact us.

Company information
Our company's origins trace back to Kyōritsu Resin Craft Co., Ltd., which manufactured FRP fishing boats and water taxis in Kamimachi, Kitamatsuura District, Nagasaki Prefecture (now the Kamimachi area of Sasebo City). The company began producing artificial marble at the Takada factory in 1981, but in 1983, it was separated and absorbed, leading to the establishment of Kyōritsu Sangyō Co., Ltd., which started artificial marble production that same year. Unfortunately, Kyōritsu Resin Craft Co., Ltd. was later transferred to Yanmar Diesel Co., Ltd. and could not leave its name behind. However, in the 1980s, it was the first in Japan to produce washbasin counters for morning shampooing using artificial marble, and while refining the technology inherited since its establishment, it has supplied washbasin vanities, toilet hand-washing counters, kitchen counters, and more, primarily to major housing equipment manufacturers. Our company's most notable feature is our integrated system that allows us to complete the entire process from FRP mold creation to product manufacturing in-house, enabling us to achieve lower costs compared to other companies. By producing from our own molds, we can more faithfully reflect our customers' preferences and accommodate complex shapes and various sizes. Please feel free to contact us when you need our services.
