This research is concerned with developing evaluation methods that can be useful for environmental design from the psychological perspective of QOL, that is comfort, in underground space. For this research, eight stations on the Tokyo Metro, including the Fukutoshin line, were selected and two types of questionnaires were carried out after respondents had walked through the station areas and the walkways connecting the stations.
 From the results of the first questionnaire, four factors, comfort/convenience, insecurity, visibility/noticeability, brightness/ease of walking, were extracted. From the results of the second questionnaire, three factors were extracted: visibility of noticeboards, overall atmosphere of underground space, visibility of fare chart/subway map. There was a strong correlation between the factors comfort/convenience and insecurity, extracted from the first questionnaire, and the overall atmosphere factor extracted from the second questionnaire. For visibility/noticeability, there was a strong correlation with notices, fares chart, and subway map.
