Founded in 2020 by Masato Igarashi, IGArchitects is an architectural practice based in Tokyo and Saitama, Japan. The studio, one of the winners of the ArchDaily 2025 Next Practices Awards, explores enduring architecture through a careful yet assertive treatment of structure, scale, and materiality. Prior to establishing his own practice, Igarashi worked at the large-scale firm Shimizu Sekkei as well as the Suppose Design Office, gaining experience across projects ranging from major developments to smaller, concept-driven works. This breadth of experience continues to inform IGArchitects' current focus on residential and commercial architecture across Japan.
