Kengo Kuma has a philosophy: to enrich the connection between buildings and nature, \u201calmost tuning-in\u201d to the materials. His architecture is inspired by traditional Japanese design, and he is a serious critic of the global dominance of concrete. Kuma\u2019s mission has manifested in iconic buildings including China\u2019s Folk Art Museum, the V&A in Scotland, and Japan\u2019s National Stadium, built for the 2020 Olympics. Broadcaster Nick Luscombe follows Kuma to Japan\u2019s oldest and largest lake, and to the ancient capital of Otsu, where Kuma is attempting to represent the history of the area not by constructing a new building, but by creating a monument to a legendary cow.
