This manuscript documents Boyd’s impressions of Expo 70 in Osaka (pdf). In it Boyd is critical of the exhibited buildings, suggesting that they fall into two categories that he labels sophisticated and naive, but likening both categories to the creations of a mad scientist. Boyd notes a visual conflict “between the order of monolithic sculptural concepts and the calculated confusion of semi-pseudo scientific systems” that is immediately apparent in the central Festival Plaza. He concludes that the Expo does not reflect the Metabolist vision or present a convincing proposition for the future of architecture or urbanism. The version published in The Architectural Review (UK) in August 1970 is extensively illustrated (pdf).

Following this same trip, Boyd wrote A Glimpse of the Future, published in The Architectural Forum (USA) in March 1970 (pdf).
