Some of the prototypes she produced for the Salon d’Automne held two years later —Equipement intérieur de l’habitation—a project signed by Le Corbusier, Pierre Jeanneret, and Charlotte Perriand, provoked a chain reaction that has not yet come to an end. In 1940, Perriand was invited to Japan to be the offi cial advisor on industrial design for the Ministry of Trade and Industry. She recommended that the Japanese turn their eff orts to creating products for export to the West. Unfortunately, her stay was cut short by the outbreak of World War II. Unable to travel back home due to the naval blockades, she stayed in Vietnam for four years until the war ended. Th ere she learned about weaving, woodwork, rattan, and other natural products. After this experience, she turned to the radical idea of using more rustic materials such as bamboo and cane to create more affordable, mass-produced furniture.
