Along with castings from the original molds of Rodin's Gate of Hell, The Burghers of Calais, and The Thinker, the wealthy businessman Matsukata Kojiro (1865–1950) acquired some 850 paintings, sketches, and prints by such masters as Renoir, Monet, Gauguin, van Gogh, Delacroix, and Cézanne. Matsukata kept the collection in Europe, but he left it to Japan in his will. The French government sent the artwork to Japan after World War II, and the collection opened
to the public in 1959 in a building designed by Swiss-born architect Le Corbusier. Since then, the museum has diversified a bit; more recent acquisitions include works by Reubens, Tintoretto, El Greco, Max Ernst, and Jackson Pollock. The Seiyo is one of the best-organized, most pleasant museums to visit in Tokyo.
