The halal industry is a new opportunity in the industrial world, which is currently being loved by countries in the world. The large number of world Muslims, which make up a third of the world’s population and the growing needs of the millennial Muslim generation, are the reasons countries in the world are starting to explore the halal industry market, including the tourism industry. Currently, the government and business actors are starting to pay attention to the halal industry, and even the halal industry is not only in demand by Muslims, but many non-Muslims are interested in the halal industry. Previously, halal tourism was only a model or additional service package or extended services amenity that was indicated and provided to meet the experiences and desires of Muslim tourists. This book reviews developments, potentials, activities, constraints, and strategies in developing halal tourism and its prospects in the tourism industry.
