Casa Cosmos was born as a children's bookstore that transcends its commercial function to establish itself as a space of imagination, connection, and affection. Inspired by the desire to create a playful yet welcoming environment, Casa Cosmos proposes that, through books and fantasy, children and adults can gather, share experiences, and envision new possible realities.
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.
