The Seto Inland Sea "Henkotssu" Archive, completed in 2022, stands as a contemporary addition to Naoshima's architectural landscape. This office building was designed through the collaborative vision of Hiroshi Ohno of Ohno JAPAN and Fuminori Nousaku of Nousaku Fuminori Architectural Design Office. Located in Kagawa Prefecture, the structure exemplifies modern design principles while serving its practical function as an administrative facility. The building's thoughtful integration into its island setting reflects the designers' commitment to harmonizing contemporary architecture with the unique character of the Seto Inland Sea region, making it a notable reference point for those interested in contemporary Japanese architecture.
