About Koukan Dekirukun

Koukan Dekirukun, Inc. operates an e-commerce platform specializing in the sale and installation of residential equipment. The company provides a one-stop service that covers online estimations, orders, replacement work, and after-sales support for products like water heaters, toilets, gas stoves, and faucets. This model eliminates the need for on-site inspections for quotations, streamlining the process and reducing costs, which are then passed on to the customer.

Founded in November 1998 by Masaru Kurihara, who had a background in IT sales, along with his brother who was a waterworks craftsman, the company aimed to address the lack of transparency in the home renovation industry. They launched the e-commerce site "Sanrifure Plaza" in 2001, pioneering an online, fixed-price model for equipment and installation. The company rebranded to Koukan Dekirukun and was listed on the Tokyo Stock Exchange Growth Market in December 2020. The business model is centered on a direct-to-consumer approach, generating revenue by selling equipment and installation services as a package. The company has also expanded into the B2B sector through acquisitions and partnerships, developing a cloud platform for more complex projects and business clients.

A key feature is the online quotation system, which uses customer-provided photos to generate accurate estimates. The company emphasizes reliability and quality by handling the entire process, from sales to after-sales service, in-house and offering a free 10-year warranty on all products. Recently, Koukan Dekirukun established a subsidiary in Singapore, KOUKANDEKIRUKUN ASIA PTE. LTD., to research the Southeast Asian residential equipment market, foster partnerships with overseas companies, and enhance its IR activities for foreign investors.
