The area that would later become known as Sakai has been inhabited since approximately 8,000 BC. [6] Sakai is known for its keyhole-shaped burial mounds, or kofun, which date from the 5th century. The largest of these, Daisen Kofun, is believed to be the grave of the Emperor Nintoku and is the largest grave in the world by area. During the Kofun period between 300 and 500 AD, the Mozu Tumulus Cluster was built from over one hundred burial mounds. [6] The name "Sakai" appears in Fujiwara Sadoyori's poetry by 1045. [7] Most of the current city is located within ancient Izumi Province; however, the wards of Mihara, Higashi and a portion of Kita are located within ancient Kawachi Province.

Tradition holds that 10,000 homes burned to the ground in 1399. [7]

Middle Ages

Medieval Sakai was an autonomous city run by merchant oligarchs. During the Muromachi and Sengoku periods from about 1450 to 1600, Sakai developed into one of richest cities in Japan as a port for foreign trade. It was a leading producer of textiles and ironwork. [8] In those days, it was said that the richest cities were Umi no Sakai, Riku no Imai (tr. "along the sea, Sakai; inlands, Imai"; the latter is now a part of Kashihara, Nara). The famous Zen Buddhist priest Ikkyū chose to live in Sakai because of its free atmosphere. The first reliable account of the city is dated to the 1480s and contains publicly issued legal notices, which suggests that the city had a governing council at that point. By the 1530s, the population was around 40,000 residents, almost all of which earned a living through commercial enterprises and some of which were the wealthiest people in Japan. At this time, Sakai was administered by an oligarchy of powerful merchants. The government had ten divisions machi that were subordinate to the representative council of wealthy townsmen known as the egoshu. [8] [9]

Sen no Rikyū, known as the greatest master of the tea ceremony, was originally a merchant of Sakai. Because of the close relationship between the tea ceremony and Zen Buddhism and because of the prosperity of its citizens, Sakai was one of the main centers of the tea ceremony in Japan.

In the Sengoku period, Christian missionaries, including Francis Xavier in 1550, visited Sakai and documented its prosperity. Gaspar Vilela described the town as the safest place in the area when he visited in 1561. [10] He also mentioned that the city was "governed by consuls like Venice in Italy". [8] [11]

After the coming of Europeans, Sakai became a manufacturing base of matchlock firearms and a daimyō , Oda Nobunaga, was one of their important customers. During his ambitious attempt to unify Japan, Nobunaga attempted to take the autonomy privilege from Sakai. Sakai's citizens denied his order and pitched a desperate battle against his army. Most citizens fled and Sakai was burned and seized by Nobunaga.

After the assassination of Nobunaga in 1582, Toyotomi Hideyoshi, seized power and abolished the autonomous system of Sakai, forcing many merchants to move to his stronghold in Osaka. [12]

In 1615, Sakai was razed to the ground in the SummerCampaign of the Siege of Osaka between the Toyotomi clan and Tokugawa Ieyasu. [7]

Sakai was restored as an important trade center during the Edo period but was involved only in inland trade due to the sakoku policy of the Tokugawa shogunate, which isolated Japan from the outside world. It was also known for its sake brewing and its cutlery industries. After the isolation policy was abandoned during the Bakumatsu period, Sakai was the location of the Sakai Incident, involving a clash between French sailors and Japanese gendarmes resulting in multiple casualties. When the Western powers demanded the opening of Osaka a port for foreign trade, both Sakai and Hyōgo were named as candidates; however, Sakai's proximity and ease of access to Kyoto and the presence of many imperial tombs led to the selection of Hyōgo.

Modern Sakai

Following the Meiji restoration, Sakai was transformed into an industrial center as part of the Hanshin Industrial Region, with industries centering on textiles and brick making. From 1876 to 1881, Sakai was part of Nara Prefecture. The city of Sakai was proclaimed on April 1, 1889 with the creation the modern municipalities system. It was one of the first 31 cities to be created in Japan. The 1934 Muroto typhoon killed over 300 people in Sakai. Another major disaster was in 1945, when the city was heavily bombed on six occasions during World War II with over 1800 civilian deaths. Following the February 2005 annexation of the town of Mihara (from Minamikawachi District), Sakai became a designated city in April 2006 [13] giving it a greater measure of self-determination in governmental affairs.


Sakai has a mayor-council form of government with a directly elected mayor and a unicameral city council of 52 members. Sakai contributes eight members to the Osaka Prefectural Assembly. In terms of national politics, the city is divided between the Osaka 15th district, Osaka 16th district and Osaka 17th districts of the lower house of the Diet of Japan.

However, after the period of high economic growth after War War II, along with the development and expansion of the Osaka metropolitan area, Sakai also has lso increased become a satellite city (commuter town) for Osaka metropolis, as represented by the development of Senboku New Town. Shimano, a major manufacturer of cycling and fishing products, is based in Sakai.

Grand Kitano Tea Ceremony

The Grand Kitano Tea Ceremony, also known in English as the Grand Kitano Tea Gathering, was a large Japanese tea ceremony event that was hosted by the regent and chancellor Toyotomi Hideyoshi at Kitano Tenmangū shrine in Kyoto on the first day of the tenth month in the year Tenshō 15 (1587). Japanese cultural historians view it as a major cultural event of the Momoyama period. Louise Cort points out these three reasons: The event was "a key move in Hideyoshi's strategy to prove his cultural legitimacy; a turning point in the development of chanoyu style and theory; and a crisis in the personal relationship between its chief designers, two of the most influential figures of the Momoyama period, Hideyoshi and Sen no Rikyū".
