Though initially developed for other purposes, it became a post town when Tokugawa Ieyasu extended the Tōkaidō with the creation of the Ōsaka Kaidō in 1601.
Those who traveled through Hirakata-juku for sankin kōtai were generally those who were direct descendants of Ieyasu, including the fudai.
During the Meiji period, train lines were developed, which had a negative effect on the post town's economy.
It was a long and thin post town that was bordered to the north by the Yodo River, the south by Hirakatagaoka, and the west by Mount Mannenji.
In Mitsuya, which was the center of the post town, there was one honjin and two sub-honjin, in addition to numerous other buildings for other travelers, whether they were coming by land or river.
