It is possible to divide the historical changes of slope revegetation in Japan into five periods as follows; 1) The early period after creation(1927-1948), 2) The spreading period of modern revegetation work with manpower(1947-1958), 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985${\dots}$), 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995${\dots}$), 5) The developing period of nature restoration technique using endemic arborous species(1996-). Recently main purpose of slope revegetation has been developing from the erosion protection to the nature restoration in the current of the 5th period. It is said that the role of the Japanese Society of Revegetation Technology(JSRT) is critical to the history of slope revegetation in Japan. 'The tentative guidelines of slope nature restoration' was announced by JSRT in 2004. In the guidelines, it was proposed that the planning techniques of using suitable seeds/plants based on the preservation level at the each construction sites. Moreover, the use of soil seed bank is the new and important study theme in the field of nature restoration. Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing. Finally, some critical concepts are necessary to develop the field of restoration in Korea as follows; 1) monitoring of constructed sites, 2) ensuring of biodiversity, 3) recognition of slow revegetation and mosaic arrangement in revegetation, 4) reuse and recycle on the construction sites, and 5) promotion of specialist.

The historical changes of seeding work in Japan, the typical slope revegetation method, is possible to divide into five periods as follows; 1) The early period after creation(1927-1948) 2) The spreading period of modern revegetation work with manpower(1947-1958) 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985${\dots}$) 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995${\dots}$) 5)The developing period of nature restoration technique using endemic arborous species(1996-) The evaluation basis of vegetated condition after slope seeding has been described to a official guide book, "The Standards of Slope Stabilizing Works" It was mainly revised three times after first edition in 1972, and also the point of evaluation basis changed from the vegetation coverage to the density of woody plant through the 3rd period and the 4th period Recently main purpose of slope seeding has been developing from the erosion protection to the nature restoration in the current of the 5th period, and "The tentative guidelines of slope nature restoration" was announced by The Slope Revegetation Section of Japanese Society of Revegetation Technology in 2004. It was proposed the planning techniques of using suitable seeds/plants based on the preservation level at the real each construction sites Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing.
