Surabaya is the capital city of the East Java province in Indonesia and holds the distinction of being the second-largest city in the country after Jakarta. It’s located on Java Island’s northeastern corner, facing the Madura Strait, making it one of the earliest port cities in Southeast Asia. Surabaya is also known as the “City of Heroes” due to its critical role in the Indonesian National Revolution, specifically in the Battle of Surabaya. It’s a key financial, commercial, industrial, and entertainment hub in Indonesia. The city’s Port of Tanjung Perak is the country’s second-busiest seaport.
