This study examines tourists' attitudes towards tourist-tourist encounters. The appearance and the number of observed tourists as well as the place of residence of the observing tourists were studied. The variables of tourist appearance and the number of people at the site were manipulated electronically in a set of rainforest photographic images. The data were collected through an on-site self-administered questionnaire. The results from 409 respondents suggested that there were different encounter preferences between Japanese and Western observers with respect to both appearance and the number of people encountered. Japanese have a preference for mixing with Westerners, at least in the rainforest setting studied. Westerners do not have marked appearance-related preferences. For the number of people in the setting, Westerners are inclined to favour few or no people while Japanese prefer some people and are tolerant of larger numbers. These findings, which contradict much of the existing North American recreation based work on people in contact, were examined from a number of theoretical perspectives, including in-group and out-group analyses, and dynamic encounter norms. Some potential management implications were outlined.
