AbstractThis study empirically investigates the major factors that determine customer satisfaction in local government offices in Japan by using three categories of questions. They referred to customer satisfaction studies worldwide, especially to the expectancy disconfirmation model, the SERVQUAL model, and subsequent methods that emphasize customer’s direct experience. The on-site surveys were conducted at the Kurose branch office in Higashihiroshima City. A total of 240 responses were obtained over six weekdays. The regression analysis showed that staff responses and explanations were the most influential, followed by aspects related to the physical office and service delivery quality (adjusted R2 value of .51).
