Was a japanese architect and structural engineer. He is considered the “father of the Japanese skyscraper” for his contributions to earthquake engineering. He entered the department of Architecture at Tokyo Imperial University (now the University of Tokyo) in 1922 and graduated in 1925. In 1935 he was appointed Professor of Structural Engineering, a post which he held for almost 30 years, developing and teaching the principles of earthquake-resistant design. After retiring from the University of Tokyo in 1963, Muto became executive vice president of Kajima Corporation, a major construction company. He also founded his own company, the Muto Institute of Structural Mechanics, in 1965. At Kajima, he led the team that designed Japan’s first high-rise building, the 36-story Kasumigaseki Building. Among his innovations for this building was first energy dissipation system used in Japan, a slit wall system consisting of precast reinforced concrete strips that stabilized the building under strong winds and small earthquakes and absorbed the energy of strong earthquakes
