Almost all subsequent significant large sculpture in Japan was Buddhist, with some Shinto equivalents, and after Buddhism declined in Japan in the 15th century, monumental sculpture became largely architectural decoration and less significant. However sculptural work in the decorative arts was developed to a remarkable level of technical achievement and refinement in small objects such as inro and netsuke in many materials, and metal "" or Japanese sword mountings. In the 19th century there were export industries of small bronze sculptures of extreme virtuosity, ivory and porcelain figurines, and other types of small sculpture, increasingly emphasizing technical accomplishment.
