Research Abstract	To introduce stomata analysis into Japanese sediments for the first time, the stomata key was prepared based on stomata observation of conifer distributed in Japan and the stomata analysis was applied using sediments from the area dominated by coniferous forests. From stomatal morphology, Japanese coniferous species were divided into 11 taxa that were larger than the division from pollen morphology and this shows stomata analysis is useful for identification of coniferous taxa. By application of stomata analysis in mainly Abies mariesii forests, it was found that occurrence of stomata corresponded with distribution range of forests than those of pollen and it shows stomata analysis is useful for reconstruction of local vegetation.
