The Tenggerese are an indigenous ethnic group residing in the Bromo Tengger Semeru National Park area of East Java, Indonesia. They are known for their unique culture, which blends elements of Hinduism and local traditions. The Tenggerese primarily speak the Javanese language and are recognized for their agricultural practices, particularly in cultivating rice and vegetables in the mountainous terrain. One of the most notable aspects of Tenggerese culture is the annual Yadnya Kasada festival, where they offer sacrifices to the Mount Bromo volcano. This event reflects their deep spiritual connection to nature and their belief in the importance of maintaining harmony with the environment.
