 note = {This report summarizes the results of an inquiry, which was conducted between the 1965 and 1977 fiscal years, into the reliability of the Linguistic Atlas of Japan. At the time of this survey, the Linguistic Atlas of Japan (Report 30, published 1966 to 1974) consisted of a collection of expressions selected from the Japanese language used nationwide, which were used in specified contexts by people of a specified age, sex, and residence history within a specified semantic range. The geographic distributions of these expressions are given on maps in the Linguistic Atlas of Japan. In the section of the National Language Research Institute which directed this research we conducted various small scale surveys throughout Japan in order to ascertain the nature of the Linguistic Atlas of Japan while drawing the linguistic maps for the atlas. These surveys, which formed the present study, Reliability of the Linguistic Atlas of Japan, aimed to examine the diversity within linguistic varieties and other related aspects which were studied in the Linguistic Atlas of Japan. The majority of these surveys are noted for their research methodologies in the fields of sociolinguistic dialectology and structural dialectology.
