According to Japanese census data, the population of Sakai increased rapidly in the 1960s and 1970s, and has been relatively stable since.

The area that would later become known as Sakai has been inhabited since approximately 8,000 BC. 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. The name "Sakai" appears in Fujiwara Sadoyori's poetry by 1045. 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.

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. 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 whom 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 egōshū.
