International tourists in Japan are increasing year by year, and the Japanese government keeps promoting the tourism industry. In order to make Japan more attractive for tourists, the analysis of tourists' impressions is very important. One of the conventional approaches is to provide tourists with a questionnaire about sightseeing spots. However, the questionnaire has a problem, the memory of the interviewees fades and fine information cannot be obtained. In this paper, we describe a novel approach to detect the impression using information from electroencephalogram (EEG). Since the developed system makes use of a portable EEG device, it enables impression detection even if the subject is walking. In order to confirm the validity of the proposed system, we carried out both video-based and real-world experience of the typical sightseeing spots.
