Le Coffre Rouge, completed in 1974, is a striking residential building located in Kohoku Ward, Yokohama, Kanagawa Prefecture. Designed by Kurosawa Takashi's research laboratory, this structure exemplifies the innovative architectural approaches of the 1970s Japanese modernism. The building's distinctive name, meaning "red chest" or "red coffer," reflects its bold aesthetic identity. With its carefully considered spatial composition and thoughtful integration into the urban residential context, Le Coffre Rouge represents an important work in the evolution of Japanese residential architecture during this dynamic post-war period.
