We studied the succession of woody vegetation and topsoil development on shallow landslide scars along sea cliffs distributed on the Satsuma Peninsula, Kagoshima Prefecture, Japan. Six plots on the steep slopes of shallow landslide scars were selected after a time period of 3 – 43 years following the occurrence of shallow landslides. The results show that the maximum tree height, diameter at breast height, number of trees and tree species, breast height cross-sectional area, Fisher-Williams diversity index, and proportion of evergreen broad-leaved trees in all of woody plants increase with time following a shallow landslide event. Woody vegetation successively develops on the topsoil in the shallow landslide scars. The rate of topsoil development in the shallow landslide scars (0 . 41 cm year－1) is slower than that in shallow landslide scars of mountainous areas in the same prefecture. Severe environmental conditions along the sea cliffs lead to the poor development of woody vegetation. Specifically, the woody vegetation is severely damaged by blowing sand and strong salty winds, and remains poorly developed compared with shallow landslide scars of the regional mountainous area.
