Aronkasei Co., Ltd., a member of the Toagosei Group, developed the first rigid PVC piping product in Japan back in 1951 called ARON PIPE. Since then, the company has been a pioneer in infrastructure products including joints, chambers and more. Aronkasei has also harnessed its assembly and processing technologies to become a market leader in nursing care products, including the Anjyu brand of portable toilets. Today, Aronkasei focuses mainly on infrastructure products, nursing care products and elastomer compounds, but it is also utilizing its unique approach to manufacturing plastic materials to expand its reach into solutions for daily living and community development through infrastructure development.
