(b Mexico City, 29 March 1915; d Mexico City, 25 May 1959). Mexican architect, theorist and writer, of Japanese descent. The son of a Japanese ambassador in Mexico, he studied philosophy, espousing neo-Kantianism and becoming politically a socialist. He became a supporter of Functionalism, with its emphasis on the social applications of architecture, and was a founder, with Enrique Ya?ez, of the Uni?n de Arquitectos Socialistas (1938), helping to draw up a socialist theory of architecture. He was one of the most active participants in the Uni?n and attempted to put his socialist theory into practice on two unexecuted projects in the same year: the building for the Confederaci?n de Trabajadores de M?xico and the Ciudad Obrera de M?xico, both with Enrique Guerrero and Ra?l Cacho. Later, when Mexico opted for a developmental policy, Arai became a standard-bearer for nationalism in architecture. He re-evaluated traditional building materials, such as tree trunks, bamboo, palm leaves and lianas, using them in a plan for a country house that was adapted to the warm, damp climate of the Papaloapan region. The building of the Ciudad Universitaria, Mexico City, gave him his greatest architectural opportunity when he designed the Frontones (1952). In these he used the volcanic stone of the area to great effect in truncated pyramid shapes inspired by Pre-Columbian pyramids. His numerous books and articles addressed conceptual problems in Mexican architecture.
