The opening of Japan to the West in 1868 led to the adaptation of the European architectural tradition. After World War I the Japanese began to make their own original contributions to the development of the International style in modern architecture. Japanese architects incorporated Western technical innovations into buildings combining traditional and modern styles during the period following World War II. At first strongly influenced by Le Corbusier, Mies van der Rohe, and, to a lesser degree, by Frank Lloyd Wright, by the mid-1960s major Japanese architects developed highly individual and imaginative visions that had worldwide following. Among the principal Japanese architects to gain international acclaim since 1950 are Kenzo Tange, Sutemi Horiguchi, Kunio Maekawa, Togo Murano, Yoshiro Taniguchi, Noriaki Kurokawa, and Arata Isozaki.
