Kurokawa, Noriaki (nôrēä'kē kOOrō'käwä) [key], 1934–, Japanese architect. Youngest of the group of architects known as the metabolists, who perceive architectural works as living organisms, Kurokawa plans for the growth or change of his buildings by addition or subtraction of modular units. The Takara Beautilion (1970, Osaka), the Toshiba IHI Pavilion, Hawaiian Dreamland (1966–67), and the Nitto Foods Co. plant in Sagae, Japan, are among his best-known designs.
