I visited Hiroshima in February 2011. While looking for attractions, I discovered that the Hiroshima Museum of Art had a special exhibition, "Image of the Seine: Impressionists and Japanese painters" on Japanese artists working in France. The museum's permanent collection has works by Manet, Degas, Monet, Renoir, Van Gogh, Tolouse-Lautrec and Picasso. The museum was on the small side, but the special exhibition more than made up for it. It's also a fairly short walk to Hiroshima Castle from the museum.
