Tuban is a town located on the north coast of Java, in Tuban Regency, approximately 100 km west of Surabaya, the capital of East Java. Tuban is surrounded by Lamongan in the east, Bojonegoro in the south and Rembang, Central Java in the west.
As an ancient town, Tuban is of considerable historical and cultural value. The most prominent feature is the beauty of the scenery such as beaches, caves, and forests, especially the teak forest.
Tuban was formerly an important port in the Majapahit era and is mentioned in Chinese records from the eleventh century. An ancient anchor from one of Kublai Khan's ships is preserved in the historical museum. Tuban is believed to have been Islamised before its conquest by Demak c. 1527. Even following its Islamisation, it remained loyal to Hindu-Buddhist Majapahit in the interior. The grave of Sunan Bonang, a sixteenth-century Islamic missionary - one of the Wali Sanga involved in the initial spread of Islam in Java, is located in Tuban. This site is an important destination for Muslim pilgrims.
