Landscape became one of objects as national monuments from 1911 to 1929, when various activities of preservation had started. At the beginning, landscape was one of many monuments to be preserved. Concepts of landscape were belonged to natural monuments in 1914. From 1915 to 1920, categories of national monuments had been discussed. Through the discussions, landscape shifted its position from natural monuments to meisho, which originally means a place of scenic beauty. On the other hand, natural monuments include Natural Reserve as preservation area. In 1927, new perceptions of landscapes, which focused on natural geography, were spread over to Japan. Under the influence, those new types of landscapes were designated as "natural monument and meisho", which indicates Natural Reserves. It shows very complicated situation for landscape as a national monuments. Along these transitions, aim of preservation also changed from development to strict preservation. Those facts suggest difficulty of creating system for preservation of landscape. In these days landscapes of Satoyama have been paid attentions as new categories both in natural parks and national monuments. Systems of how to preserve those landscapes are now developing, though difficulties of setting landscapes as objects for preservation must be unchanged.
