This study empirically investigated the major determinative factors regarding customer satisfaction in local government offices in Japan, comparing them with the results of similar surveys conducted by the author in 2020. The surveys comprise three categories of questions, referring to (1) customer satisfaction research in various countries, especially the expectancy disconfirmation model; (2) the SERVQUAL model; and (3) subsequent methods that emphasize the customer’s direct experience. A total of 1,000 questionnaires were distributed over four weekdays at the City Hall. As of September 27, 2021, there were 537 respondents (response rate: 53.7%). The regression analysis showed that the independent variables of group C (service delivery) were most influential, followed by those of groups B (human-related factors) and A (office hardware) (adjusted R² value: .58). This is consistent with the results of the author’s Internet survey of users of Osaka City Government’s ward offices.
