Sera

Sera lies in the uplands of Bingo, where much of the district once formed the great estate of Ōta. From the late twelfth century, the estate belonged to the temples of Mount Kōya, and Ryūgeji, known as Ima Kōyasan, became a local religious centre. In 1190 the estate possessed hundreds of hectares of cultivated fields. As warrior influence grew toward the end of the Kamakura period, the temple's relative power declined.
