The area of the modern town of Taishi was within ancient Kawachi Province. The area has been inhabited since the Japanese Paleolithic, due to the abundance of raw materials for stone tools from Mount Nijō. During the Asuka period, the Takeuchi Kaido, one of Japan's first "official roads", which connected the port of Sakai with Yamato Province was constructed. It was used by Ono no Imoko and others during the Japanese missions to Sui China. Around this time, Yamato's Asuka was called "Far Asuka", while the area around Taishi Town was called "Nearby Asuka". The town has many imperial tombs, including that of Emperor Bidatsu, Emperor Yōmei, Empress Suiko, and Prince Shotoku.

The villages of Isonaga and Yamada were established within Ishikawa District with the creation of the modern municipalities system on April 1, 1889. On April 1, 1896 the area became part of Minamikawachi District, Osaka. The two villages merged on September 30, 1956 to form the town of Taishi, which was named after Prince Shotoku.
