The article by Y. Ota and S. Odagiri (1994) on the age and deformation of marine terraces developed in Ashizuri area, Southwest Japan is welcome. Over the past several ten years a number of occurrences on the marine terraces ranged Holocene from late Quaternary have been reported in this area. Their article does not only make these important findings integrate on the successive time scale, but also shows the absolute age of terrace deposits by means of tephrochronology.<BR>However, there are some questions especially in the discussion on Holocene terraces. This short comment aims to submit the questions to the public. Those questions are summarized as follows ;<BR>1. Some parts of discussion comes up without the description of Holocene terraces which were indicated in the preceding papers (Maemoku, 1988 and others).<BR>2. Some of the raised landform which Ota and Odagiri described can not be considered as the evidence for Holocene coastal uplift judging from their depositional or geological condition especially in the highest level terrace.<BR>3. Some of the interpretation on the age for Holocene uplift contradict themselves.
