Keiji Kobo kara: Toyoguchi Katsuhei to Dezain no Hanseiki is a comprehensive retrospective publication by Katsuhei Toyoguchi, bringing together decades of writings, reflections, essays and archival material spanning more than half a century of design practice. Compiled in the later years of his career, the book traces Toyoguchi’s trajectory from his formative years at Keiji-Kobo through his role in shaping modern Japanese design during the country’s rapid post-war transformation.

Rather than functioning solely as a monograph, the publication offers a personal and critical account of Japanese modernism from the perspective of one of its central figures. Through texts on furniture, ergonomics, exhibition design and design education, Toyoguchi reflects on themes that defined his work: the relationship between body and object, the modernization of everyday life, and the tensions between creative practice and design as industrial policy.

Richly illustrated with sketches, photographs and archival documents, the volume also includes reflections on projects such as the Montreal Expo and provides rare insight into the intellectual and cultural environment that shaped twentieth-century Japanese design. Today it remains an important reference for understanding both Toyoguchi’s work and the broader development of modern design culture in Japan.
