Surabaya is the capital and largest city of East Java province and the second-largest city in Indonesia, after Jakarta. Located on the northeastern corner of Java island, on the Madura Strait, it is one of the earliest port cities in Southeast Asia. According to the National Development Planning Agency, Surabaya is one of the four main central cities of Indonesia, alongside Jakarta, Medan, and Makassar. The city covers a land area of 334.50 km2, and had a population of 2,874,314 within its city limits at the 2020 census. With 3,003,860 people living in the city as of mid 2025 (comprising 1,487,077 males and 1,516,783 females) and over 10 million in the extended Surabaya metropolitan area, according to the latest official estimate, Surabaya is the second-largest metropolitan area in Indonesia. Surabaya metropolitan area also has ASEAN's 6th largest economy, ahead of Hanoi. In 2023, the city's GRP PPP was estimated at US$150.294 billion.
The city was settled in the 10th century by the Kingdom of Janggala, one of the two Javanese kingdoms that was formed in 1045 when Airlangga abdicated his throne in favor of his two sons (the other was the Kediri kingdom). In the late 15th and 16th centuries, Surabaya grew to be a duchy, a major political and military power as well as a port in eastern Java, probably under the Majapahit empire. At that time, Surabaya was already a major trading port, owing to its location on the River Brantas delta and the trade route between Malacca and the Spice Islands via the Java Sea. During the decline of Majapahit, the lord of Surabaya resisted the rise of the Demak Sultanate and only submitted to its rule in 1530. Surabaya became independent after the death of Sultan Trenggana of Demak in 1546.
From the 18th century until the mid-20th century, Surabaya was the largest city in the Dutch East Indies and the main trading hub for the Indonesian archipelago, competing with Shanghai and Hong Kong.
Surabaya has been one of the busiest trading city ports in Asia. Principal exports from the port include sugar, tobacco, and coffee. Its rich history as a trading port has led to a strong financial infrastructure with financial institutions such as banks, insurance, and export-import companies. The economy is influenced by the recent growth in international industries and the completion of the Suramadu Bridge. The city is home to a large shipyard and numerous specialized naval schools. The Bank of Indonesia has also made plans for Surabaya to be the Islamic financial center of Indonesia. Surabaya is classified as a Gamma (Gamma minus) global city according to the World Cities 2024 - GaWC rankings by the Globalization and World Cities Research Network.
Manten Pegon, traditional wedding attire from Surabaya Javanese people form the majority in Surabaya, with about 83 percent of the population, while the Madurese and Chinese are significant minorities, each making up about 7 percent of the population. Smaller groups include Arabs, especially the Hadhrami people who originate from the Hadhramaut region in Yemen, Armenians, and Jewish people. Surabaya also has ethnic populations from other parts of Indonesia: Sundanese, Minang, Batak, Banjar, and Balinese.
As one of Indonesia's educational destinations, Surabaya is also the residence of students from various regions of the country, who may form communities based on the region they come from. Most come from the Eastern part of Indonesia, including those who are Papuan, Minahasan or Bugis, as well as people from Timor and others.
Because it is a regional trade hub, many foreigners (expatriates) live in Surabaya, especially in the western part of the city. There are also communities of Koreans, Japanese, Indians and westerners in the city.
Most citizens speak a dialect of East Javanese called Suroboyoan, a subdialect of the Arekan dialect. A stereotype of this dialect concerns equality and directness in speech. The use of register is less strict than the standardized Central Java dialect. The Suroboyoan dialect is a mixture of both Indonesian and Javanese, also with some significant influence from foreign languages such as Madurese, which has formed a distinctive dialect known as Suroboyoan. The Suroboyoan dialect is actively promoted in local media, such as in local TV shows, radio, newspapers, and traditional dramas called Ludruk. The speakers of Suroboyoan dialect are well known for being proud of their distinctive dialect and consistently maintain it wherever they go.
Ludruk is a native Surabaya-genre play (theatre) Kya Kya Surabaya (Kembang Jepun) is part of Surabaya’s Chinatown, it has chinese cuisine, barongsai attractions, and chinese heritage buildings. Javanese culture in Surabaya has distinctive characteristics compared to other regions, uniquely characterized as more egalitarian and open. Surabaya is known to have several distinctive arts, namely: Ludruk, a cultural drama performance art that tells daily routine of working-class people. Remo Dance, a traditional welcome dance is generally dedicated to special guests. Kidungan, musical poetry that contains elements of humor.
In addition to the art above, the call culture of arek or rek (a distinctive call from Surabaya) is also a unique characteristic. There are other distinctive calls as well, namely Cak for men and Ning for women. In an effort to preserve culture, Cak & Ning Surabaya is selected once a year, and the selected finalists are tourism ambassadors and icons of the young generation of the city.
Cak Durasim Festival (FCD) is held annually, which is an art festival to preserve the culture of Surabaya and East Java in general. The Cak Durasim Festival is usually held at Cak Durasim Building. There is also the Surabaya Art Festival (FSS) which raises all kinds of art forms such as theatre, dance, music, literary seminars, painting exhibitions. Event organisers usually aside from art groups in Surabaya also come from outside the city. Also enlivened is the screening of movie screens and T-shirt exhibitions. The Surabaya Art Festival is held once a year in June and is usually held at the Youth Hall.
In addition to Javanese culture, there has also been a mixture of various cultures such as from Madura, the Arab world, India, the Malay world, China and Europe. The Surabaya Cross Culture is an annual art and culture festival that show various cultures outside Indonesia.
Ultras choreography of Persebaya Surabaya is a barometer and center of association football development in Indonesia. The city has many association football clubs founded in Surabaya, but Gelora Bung Tomo Stadium is the home of Persebaya Surabaya. The first club was founded by the youth of Hoogere Burger School (HBS) John Edgar with the Victoria club in 1895. Others included Scoren Is Ons Doel (SIOD), Sparta, Rapiditas and Thot Heil Onzer Ribben (THOR). These are the pioneers of association football in Surabaya. The clubs then took management under Oost Java Voetbalbond (OJVB) in 1907. Two years later, the OJVB changed to Soerabajasche Voetbalbond (SVB). Starting in 1914, SVB was based on the Nederlandsch Indische Voetbalbond (NIVB), created by Dutch football federation (KNVB). The Surabaya Chinese and native people also founded their association football clubs by ethnicity. Oei Kwie Liem founded Hoa Soerabaja in 1914, while the Bumiputera through R Pamoedji and Paidjo founded the Soerabajasche Indonesische Voetbalbond (SIVB) on 18 June 1927 (now Persebaya), which three years later co-founded the PSSI.
In 1950, the working-class people and office men founded Soerabajasche Kantoor Voetbalbond (SKVB). The association football sector in Indonesia and specifically Surabaya became more developed, and the football association of Indonesia founded a semi-professional competition in 1979, which was named the Main Football League (Galatama). A new team emerged from Surabaya, NIAC Partners and the Salim Group Association. Besides Galatama, PSSI also formed a women's soccer competition called the Women's Football League (Galanita). Surabaya also has a women's soccer team, which was founded in 1977 and named Puteri Puspita. Clubs from Surabaya have also gained attention from the rest of the world. Persebaya has competed against European teams including Lokomotiv Moscow, Sturm Graz, Grasshoppers, Salzburg, Stade de Reims, Ajax Amsterdam, PSV Eindhoven, AC Milan, and lastly, Queens Park Rangers (QPR). Aside from European teams, there are several national teams outside the country competing against Persebaya, including Yugoslavia Olympics, Malaysia, Mozambique, Uruguay, Thailand, South Korea, and the Japanese national team.
NIAC Mitra also competed against Arsenal and won the Aga Khan Gold Cup competition in 1979 in Bangladesh. The achievements of NIAC Mitra in the Galatama competition included three championships in 1980–1982, 1982–1983, and 1987–1988, and finishing as runners-up in 1988–89. However, NIAC Partners officially dissolved and withdrew from the Galatama competition held by PSSI in 1990 because they considered the policies issued by PSSI irrelevant. After being disbanded, the demands of the Surabaya community to revive the NIAC Partners were channelled when the Jawa Pos party weighed in and changed the name of the NIAC Partner to the Surabaya Partner. When the Union competition was merged with Galatama in 1994, the new Persebaya was able to win in 1997 and 2004. Persebaya was listed as the first team capable of winning the Indonesian League twice. Mitra Surabaya was only able to exist until the 1998–1999 season and it was re-established again in another city, Tenggarong and has not used the name of Surabaya again.
Inside Gelora Bung Tomo Stadium in 2023 Recently, only Persebaya has stable fans and achievements. Persebaya has won the Indonesian Premier Division three times–twice when the division was the first tier and once as the second tier. Fans refer to themselves as Bonek, an abbreviation for Bondo Nekat (which translates as "equipped by bravery"). The city is the home of CLS Knights Indonesia, a basketball club which participated in IBL (Indonesia basketball league) & Asean Basketball League.
Surabaya has a multi-purpose stadium, Gelora Bung Tomo Stadium. The stadium is used mostly for football matches. It is the new home stadium of Persebaya, replacing Gelora 10 November Stadium. It was the venue of a match between Persebaya 1927 against then–English Premier League club Queens Park Rangers, held on 23 July 2012.
Another prevalent sport is badminton. There are numerous schools and clubs in the city that train students of various ages to reach the next level of the Badminton League. Many children start out their career from Surabaya and have made it to the national and sometimes international level.
One of the largest circulating national newspapers in Indonesia, Jawa Pos, is headquartered in Surabaya; alongside its media conglomerate Jawa Pos Group. Major newspapers include Surabaya Pagi and Surya.
Surabaya is served by many radio and television networks. Radio networks affiliates include the public RRI Surabaya, Gen FM Surabaya 103.1 and Prambors FM Surabaya 89.3; as well as local stations Suara Surabaya 100.0, EBS FM and Radio Merdeka 106.7. Local television stations include JTV (both are regional stations serving East Java, which are based in the city), Jawa Pos TV, Surabaya TV and Nahdlatul Ulama-affiliated TV9.
The Kingdom of Janggala was one of the two Javanese kingdoms that were formed in 1045 when Airlangga abdicated the throne of the Kingdom of Kahuripan in favor of his two sons. The earliest historical record of Surabaya was in the 1225 book Zhu Fan Zhi written by Zhao Rukuo, in which it was called Zhòng Jiā Lú. The name Janggala is derived from the Old Javanese name Hujung Galuh. Hujung Galuh was located on the estuary of Brantas River and today is part of modern Surabaya city and Sidoarjo Regency.
By the 14th and 15th centuries, Surabaya was one of the Majapahit ports or coastal settlements, together with Tuban, Gresik, and Hujung Galuh (modern Sidoarjo). Ma Huan documented the early 15th-century visit of Zheng He's treasure ships in his 1433 book Yingya Shenglan.Ma Huan Ying-yai Sheng-lan, The Overall Survey of Ocean Shore, translated by J.V.G. Mills, p. 90, 1970, Hakluyt Society, reprint by White Lotus, 1997..
Ma Huan visited Java during Zheng He's fourth expedition in 1413, coinciding with the reign of Majapahit king Wikramawardhana. He describes his travel to the Majapahit capital. He first arrived at the port of Tupan (Tuban) where he saw large numbers of Chinese settlers migrated from Guangdong and Zhangzhou. Then, he sailed east to the thriving new trading town of Koerhhsi (Gresik), Supaerhya (Surabaya), and then sailing inland into the river by smaller boat to the southwest until he reached the Brantas river port of Changku (Canggu). Continuing to travel by land to the southwest, he arrived in ManchepoI (Majapahit), where the Javanese king stayed.
Ampel Mosque built in 1421 The Surabaya area was once the main gateway to the capital of the Majapahit Kingdom from the sea, at the mouth of Kali Mas river. The anniversary of the city of Surabaya was set on May 31, 1293, commemorating the victory of the Majapahit led by Raden Wijaya against the Mongol invasion. Mongol troops who came from the sea were described as Sura (sharks/brave) and Raden Wijaya's troops who came from the land were described as Baya (crocodiles/danger), literally translating to brave to face the dangers that come threatening. So the day of victory is commemorated as the anniversary of Surabaya.
By the late 15th century, Islam began to take its root in Surabaya. The settlement of Ampel, located around Ampel Mosque in today's Ampel village, Semampir District, northern Surabaya, was established by Islamic preacher Sunan Ampel.
In the late 15th and 16th centuries, Surabaya grew to a duchy, a major political and military power in eastern Java. The Portuguese writer Tomé Pires mentioned that a Muslim lord was in power in Surabaya in 1513, though likely still a vassal of the Hindu–Buddhist Majapahit. By that time, Surabaya was already a major trading port, owing to its location on the Brantas River delta and the trade route between Malacca and the Spice Islands via the Java Sea. During the decline of Majapahit, the lord of Surabaya resisted the rise of the Demak Sultanate and only submitted to its rule in 1530. Surabaya became independent after the death of Sultan Trenggana of Demak in 1546.
Following the collapse of Demak, Surabaya was conquered by the Mataram Sultanate, under the leadership of Panembahan Senopati in 1598, and invaded by Panembahan Seda ing Krapyak in 1610, An article by the VOC in 1620 described Surabaya as a rich and powerful region.M. C. Ricklefs, A History of Modern Indonesia since c. 1200, 2008
The Duchy of Surabaya entered conflict with and was later captured by the more powerful Sultanate of Mataram in 1625 under Sultan Agung. It was one of Mataram's fiercest campaigns, in which they had to conquer Surabaya's allies, Sukadana and Madura, and to lay siege to the city, blocking the flow of the Brantas River, Sultan Agung forced Surabaya to surrender. With this conquest, Mataram then controlled most of Java, except the Banten Sultanate and the Dutch settlement of Batavia.

The expanding Dutch East India Company took over the city from a weakened Mataram in November 1743. In consolidating its rule over Surabaya and, in time, the rest of East Java, the Dutch collaborated with leading regional magnates, including Ngabehi Soero Pernollo (1720–1776), his brother Han Bwee Kong, Kapitein der Chinezen (1727–1778), and his nephew, Han Chan Piet, Majoor der Chinezen (1759–1827), all from the powerful Han family of Lasem.
In the 18th and 19th centuries, Surabaya was largest city in the Dutch East Indies, becoming a major trading center and hosting the most extensive naval base in the colony. Surabaya also served as the center of Java's plantation economy, industry, supported by its natural harbor.
During the Dutch East Indies era, Surabaya was the capital of the Surabaya Residency, whose territory encompasses what is now the Gresik Regency, Sidoarjo, Mojokerto, and Jombang. In 1905, Surabaya received the status of municipality (gemeente). In 1926, Surabaya was designated the capital of the province of East Java. Since then Surabaya developed into the second largest city in the Dutch East Indies after Batavia.
The Pasar Besar with the OJS railway viaduct in the background, the so-called Hogeweg, Surabaya circa between 1900 and 1940 Before 1900, the city center of Surabaya revolved around the Jembatan Merah. In 1910, a modern port facility was built in Surabaya, now known as Tanjung Perak Harbor. Until the 1920s, new settlements such as Darmo, Gubeng, Rungkut, and Ketabang grew.
Surabaya was an early center for leftist political organizing in colonial Indonesia. In the 1910s, Dutch colonists founded the predecessor to the Communist Party of Indonesia (PKI), the ISDV. The success of organizing with sailors and local Indonesians led to a crackdown in 1917.
Japan occupied the city in 1942, as part of the Japanese occupation of the Dutch East Indies, and it was bombed by the Allies in 1944. After the surrender of Japan at the end of World War II, Surabaya was seized by Indonesian nationalists. The young nation soon came into conflict with the British, who had become caretakers of the Dutch colony after the Japanese surrender.
The burnt-out car of Brigadier Mallaby on the spot where he was killed by pro-independence Indonesian soldiers during the Battle of Surabaya on 31 October 1945 The Battle of Surabaya, started after the Arek-Arek Suroboyo killed British Brigadier Aubertin Mallaby on 30 October 1945, near Jembatan Merah, allegedly with a stray bullet. The Allies gave an ultimatum to the Republicans inside the city to surrender, but they refused. The ensuing battle, which cost thousands of lives, took place on 10 November, which Indonesians subsequently celebrate as Hari Pahlawan (Heroes' Day). The incident of the red-white flag (the Dutch flag at the top of Yamato Hotel's tower that was torn into the Indonesian red-white flag) by Bung Tomo is also recorded as a heroic feat during the struggle over the city.
The city is known as Kota Pahlawan due to the importance of the Battle of Surabaya in galvanising Indonesian and international support for Indonesian independence during the Indonesian National Revolution.
Recent development of Surabaya After the independence era, population growth and rapid urbanization forced Surabaya to develop towards the east and west as it is today. The increase in vehicles, the growth of new industries and the proliferation of housing carried out by real estate companies occupying the outskirts of the city have resulted in traffic jams not only in the downtown area but also frequently in the suburbs. Surabaya grew from a relative poor city in the late 19th century into a metropolis in the late 20th century, and became one of the fastest growing metropolitan areas in Southeast Asia. Surabaya also managed to become one of the most organized metropolitan cities in Indonesia with the cleanest air.
On 13 May 2018, three churches in Surabaya and one apartment complex in the neighboring regency of Sidoarjo were bombed in a series of terrorist attacks initiated by Jamaah Ansharut Daulah, the Southeast Asian branch of ISIS, followed by a bombing on Surabaya Police Department HQ the next day. 28 people were killed, including the assailants. 57 people were injured; several of whom where in a critical condition.
The first confirmed case of COVID-19 in East Java was in Surabaya, on 17 March 2020. In May 2020, Surabaya became the epicenter of the pandemic in Indonesia.
Surabaya, the capital of East Java province, extends over, its metropolitan area covers, which includes the satellite cities of Mojokerto, Gresik, Sidoarjo, Bangkalan, and Lamongan, and has an estimated population of 10.08 million, making it the Second largest urban area in Indonesia and the Top 50 largest in the world. Surabaya ranks 11th among the Indonesian city in the human development index. Surabaya's offer business and employment opportunities, along with its ability to offer a potentially higher standard of living compared to other parts of the country, have attracted migrants from across the Indonesian archipelago, making it a melting pot of numerous cultures.
The city is referred to as Kota Pahlawan (the city of heroes) due to the significance of the Battle of Surabaya during the Indonesian National Revolution. The city is one of the important financial, commercial, industrial, transportation, and entertainment hubs of the archipelago. Arguably the second most significant city after Jakarta, the city is also home to Indonesia's second-busiest seaport, the Port of Tanjung Perak, which is located in northern Surabaya. The city is also known for being one of the cleanest and greenest in Indonesia.
Wisma Intiland, most famous Brutalist architecture in Surabaya. It is one of the last buildings designed by Paul Rudolph.
Architecture in Surabaya is a mixture of colonial, Asian, Javanese, modern, and post-modern influences. There are many colonial-era relics still standing today, such as Hotel Majapahit and Surabaya Post Office. As a relatively old city in Indonesia and Southeast Asia, most colonial buildings were built around the 17th century to the early 20th century. These buildings show the influence of Dutch or European style in the Middle Ages.
Resident's house along the Ketabang River in Surabaya (late 19th century) Ketabang is an area of Genteng District of Surabaya which was planned by Dutch architect Cosman Citroen.
Before the Second World War, there were many shophouses in the old part of the city, mostly two-storey. They display the influence of European and Chinese traditions. Although some have been dismantled for new construction, there are still many old buildings that are preserved as cultural heritage and city icons, which are around the area of Kembang Jepun Street, Karet Street, Gula Street, Slompretan Street, and Rajawali Street.
After the independence of Indonesia, the center of Surabaya's architectural development was concentrated only in the area of Jembatan Merah and its surroundings. In the late 1990s and early 2000s, modern and post-modern style buildings were increasingly emerging in Surabaya. Along with economic development, such buildings have continued to grow. In the 2010s, Surabaya has become a center of skyscrapers and high-rises in East Java and central regions of Indonesia, such as The Peak Residence – Tunjungan Plaza 6 (215 meters) and One Icon Residence–Tunjungan Plaza 5 (200 meters).
Bungkul Park, one of the most visited parks in Surabaya Surabaya is among the cleanest and greenest cities in Indonesia. It has urban parks which are equipped with fountains in almost every neighborhood area. These parks include Bungkul Park, Harmoni Park, Pelangi Park, Surya Park, Mundu Park, Undaan Fruit Park, Jayengrono Park, and others. Bungkul Park was awarded the Asian Townscape Award 2013 from the United Nations as the best park in Asia because of its complete and integrated facilities, including the economic area (street food centers), green open area, disability-friendly area, free internet (Wi-Fi), and regular garden maintenance.
The city of Surabaya is very outstanding in the field of environment. The city has won many awards in the field of environment and city planning both nationally and internationally. These awards have included Adipura, Adipura kencana, Adiwiyata, Wahyu Tata Nugraha, and other green awards, the Adipura Cup, which Surabaya won several times in the 1980s and 1990s, the Adipura Kencana trophy, the cleanest metropolitan city category in the 1990s and in the period of 2010 to 2017, seven consecutive times, as well as the Adipura trophy, plenary in 2016. The city also received several awards from the central government as one of the major cities with the best air quality in Indonesia. Surabaya in 2012 has won the award "City of the Best Participation in the Asia Pacific" by Citynet for the success of the city government and people's participation in managing the environment. Surabaya has also been awarded the ASEAN Environmentally Sustainable City Award or "the city with the best sustainable environmental management in ASEAN" in 2011 and 2014. In 2018, Surabaya won the Lee Kuan Yew City Prize along with Hamburg, Kazan, and Tokyo, on the basis of the ability to maintain and manage villages in the middle of the city with excellent government management and community participation amid the rapidly developing city. Surabaya became the first city in Indonesia to receive this award. On the other hand, however, there are not a few areas in Surabaya that appear less organised, especially in the neighborhoods of Southern and Northern Surabaya. This is the concern of the city government to reorganise the environment of the region.
Surabaya features a tropical wet and dry climate (Köppen: Aw), with distinct wet and dry seasons. The city's wet season runs from October through May, while the dry season covers the remaining four months. Unlike many cities and regions with a tropical wet and dry climate, average high and low temperatures are very consistent throughout the year, with an average high temperature of around 31 °C and average low temperatures around 23 °C. Summer months (December to February) are the wettest months, while spring months (September to November) are the hottest months.
