In Kikai-jima, south-western Japan, many pedestal rocks have developed on the surface ofHolocene raised coral-reef terraces with known dates of emergence. Pedestals are formedjust under boulders, which are considered to have been transported by tsunami and settledon a reef flat before emergence. On the assumption that boulders protect the underlyinglimestone terrace from rainfall solution, the rate of surface lowering of these limestoneterraces was evaluated from the height of pedestals and the period of their formation. Theresult showed that the mean lowering rate over 6000 years is 205 mm/ky.
