In 1958, Masayuki Nagare showed a sculpture that combined warehada (cracked texture) stone, which has been roughly split to produce a rough surface texture, with polished stone in a single sculpture. The simple shape, together with the technique of splitting the stone, was highly praised for its deep spirituality first in the United States before Japan. He produced numerous monumental sculptures, both in Japan and the United States, in which he expressed traditional Japanese sensitivity through modern forms. His works make the viewer think of the universe and increase in character the longer they are exposed to the elements.
