Every person's tourism activity can be greatly influenced by one's inner or outer factors. Especially, their lifestyle and motivation have a great effect on the decision making for their tourism activities. On the basis of this hypothesis, this study firstly aimed to subdivide the customers' lifestyle into 4 groups by factor analysis. They are named ① leisure and independent core, ② hobby activity, ③ family affection, and ④ sociability. Secondly, this study empirically investigated the relationship between the customers' lifestyle and the traits of their motivation by the MDPREF analysis. Thirdly, this surveyed the traits of tourism activity according to their groups of lifestyle by the MDPREF analysis. Finally, this study investigated the causal relationship between tourism motivation and tourism activity of the cannonical correlation analysis. At the result of this survey, I came to the conclusion that these 3 types of lifestyle can be referred to the same types of market segmentations such as ① segmented market for the individualistic customers, ② segmented market for the family center customers, and ③ segmented market for the unconsciousness customers.
