Aging societies are one of the major problems faced in the modern world. Promoting subjective wellbeing is a key component in helping individuals positively accept and adapt to psychological and physical changes during their aging process. Tourism is one of the activities that have been demonstrated to promote subjective wellbeing. However, motivation for tourism and its benefits to subjective wellbeing among the older adults have rarely been discussed. The current study aimed to investigate whether tourism contributes to the subjective wellbeing of older adults. We examined the relationships between travel frequency, subjective wellbeing, and the personal trait of curiosity, mediated by the factor of family budget situation. The results demonstrated that diverse curiosity motivates individuals to travel; thus, diverse curiosity positively correlates to subjective wellbeing, both directly as well as indirectly through travel frequency. However, this relationship is limited by the factor of family budget, with tourism contributing to the subjective wellbeing of only well-off older adults. This study concludes that tourism has potential to contribute to subjective wellbeing during later stages of life.
