Vegetational data of Fagus crenata forest in the Japan Sea region of the Chubu district, central Japan, were examined by TWINSPAN classification and DCA ordination. Stands were divided and the hierarchy of each was displayed as a dendrogram, using the sequences of divisions as integral levels, Species classification was also produced. Data were ordinated by DCA. The sample sequences along first and second DCA axes effectively reflected temperature and moisture status, respectively. Vegetational structure revealed by TWINSPAN was recognized by comparing the species arranged on the DCA axes with the species characterizing the division of the same vegetation type analyzed by TWINSPAN.
