The first one is a representation of two-dimensional geographical distribution patterns by one dimension. The second one is plotting the geographical locations making use of railway distances from cultural centers. By simplifying the two-dimensional geographical distribution into one by railway distance, another dimension can show the average percentage of usage of standard Japanese forms for each prefecture. "Kasai data", or numerical data of the "Linguistic Atlas of Japan", was utilized, and columns of the word-form were analyzed. Gravity centers of railway distance were calculated for each standard Japanese form, and correspondence with the nationwide rate of usage and the first year of appearance in historical documents was considered. Two-dimensional graphs (scattergrams) of the two factors were considered, and also three-dimensional graphs were analyzed. Division of the data into Archaic and Modern words by means of first year of appearance and also division into eastern and western clusters were attempted. Archaic Eastern words did not show any correspondence with first year of appearance. However, the other three categories showed fairly good correspondence with first year of appearance. This shows that the newly appearing words from a cultural center have lower percentage of usage at first, but increase its nationwide usage rate by taking the same steps with words which had spread before. However, words which had appeared early in Archaic era may later be eroded by newer dialectal forms., application/pdf},
