The purpose of this study is to analyze “Hokori, Puraido, Jison, Jihu, Jinin, kyoji” by factor analysis, and to know its usage. Factor analysis is one of the methods of multivariate analysis. In this method, it is possible to find a criterion that is common to words with strong correlation among a plurality of variables. By applying this factor analysis to synonyms and collocation research, it is possible to improve the relevance of research such as classification and systematization. Examples obtained from “BCCWJ : Balanced Corpus of Contemporary Written Japanese”. Classification criteria are obtained from the quantitative analysis of the occurrence word. As a result of the analysis, “myself, man, country, Japanese, woman” have a strong correlation with “Hokori, Puraido, Jison, Kyoji”. In other words, “Hokori, Puraido, Jison, Kyoji” are used to mean “proud as a person or country”. On the contrary, “Jinin” has no such feature. And “professional, growth, value, technology, author” have a strong correlation with “Jihu”. In other words, “Jihu” is used for “position, work, ability”, not “person or country”. “Jihu” can express the willingness or will of the future. This is characteristic only of “Jihu”.
