TOTO Technical Center Tokyo, a place that collaborates with business users to create the water-related spaces of the future, reopened in April 2024 under the concept of "co-creation." The concept of this renovation is "Fine & Flow," expressing the "free, delicate, beautiful behavior of water and seamless transitions without interruption." We aimed not only to convey the attention to detail that only water-related professionals can provide and the reliable quality of TOTO, but also to create a facility with equipment and an appearance worthy of co-creation, and a proposal facility that should exist in the digital age. We were responsible for the overall design, construction, and system development.
