East Java is a province of Indonesia. It has a land border only with the province of Central Java to the west; the Java Sea and the Indian Ocean border its northern and southern coasts, respectively, while the narrow Bali Strait to the east separates Java from Bali. Located in eastern Java, the province also includes the island of Madura (which is connected to Java by the longest bridge in Indonesia, the Suramadu Bridge), as well as the Kangean islands and other smaller island groups located further east (in the northern Bali Sea) and Masalembu archipelagos in the north. Its capital is Surabaya, the second largest city in Indonesia, a major industrial center and also a major business center. Banyuwangi is the largest regency in East Java and the largest on the island of Java.
East Java is inhabited by many different ethnic groups, such as the Javanese, Madurese and Chinese. Most of the people in East Java adheres to Islam, forming around 94% of the total population. Other religions are also practiced, such as Christianity, Buddhism and Confusianism which are mostly practised by Tionghoa people and immigrants from Eastern Indonesia and North Sumatra, and also Hinduism which are practised by the Tenggerese people in the Bromo Tengger Semeru National Park and the Balinese people inhabiting the easternmost part of the province bordering Bali.
The Indonesian language is the official language of the province as well as the whole nation, but Javanese and Madurese are the most frequently used language, especially the Surabaya dialect (Javanese: Suroboyoan or Surabayaan — the Javanese dialect of Surabaya) used mainly in the capital Surabaya. Indonesian is only used for inter-ethnic communication and official purposes.
