Implementalist Papers looks at developments of mid-century modernist architecture in Tokyo and North Carolina with a parallel consideration of evolutionary adaptations of Japanese and American wood lice. Topics explored include the typology that zoologist Edward Sylvester Morse developed in Japan through his study of coastal brachiopods leading to his grouping of ceramic shards to establish the Jomon period, and his book Japanese Homes and Their Surroundings which greatly impacted Frank Lloyd Wright. This is paired with reflections on Kenzo Tange’s Metabolist architecture in which cities are perceived as organisms as evidenced in Tange’sHiroshima Peace Memorial.
