Natural hot springs enrich the development of tourism within a country. Local and national governments can endorse a "hot spring international brand" and advocate the health benefits of hot springs to promote their tourism policy. After the legislation of the Taiwan Hot Spring Act, Taiwanese hot springs have become a popular tourist attraction and an important asset for local governments. However, Taiwan's hot spring tourism is limited by seasonal consumption habits. In addition, mountainous land accounts for about 75% of Taiwan's total land area, and most of the hot springs originate in high mountains. Furthermore, Taiwan's hot spring development started after Japan and European countries and the scale of the industry was relatively small. Therefore, Taiwan is not conducive to the development of large-scale, internationally competitive hot spring resort centers. Still, Taiwan possesses a near-flawless hot spring law as well as progressive technological conditions in medicine, tourism, and information services, which will help promote innovation and deliver a more optimistic advantage for the development of an international hot spring brand. Over the history of the development of therapeutic spas, hot springs have been regarded as a valuable resource for preventive health care in many countries. People can combine hot springs with natural and human resources for relieving stress, rehabilitation, and recuperation. In 1993, approximately 1,700 resorts in Europe had healing spas. Japan currently has 3,000 spa resorts of various sizes and styles. In 2008, tourists from all over the world visited Japanese hot springs for leisure and holiday purposes. Meanwhile, European countries considered hot spring resorts as a place for health promotion and disease rehabilitation. There are many similarities between Taiwan and Japan, such as culture and resources. The booming hot spring and hotel industries make up a significant part of the strategy for tourism development in Taiwan. Nearby countries such as Thailand, Malaysia, and India are also actively expanding their hot spring industry and striving to incorporate hot springs into the medical tourism industry to create an internationally renowned brand.
