Ōno Castle

Ōno Castle extends across Mount Shiōji at 410 meters elevation, featuring stone walls and earthwork fortifications spanning 8.4 kilometers in total length.

The castle was constructed in 665 AD following Japan's defeat at the Battle of Hakusukinoe, serving as a defensive structure against potential invasions from Tang Dynasty and Silla.

Archaeological excavations within the castle grounds have revealed 70 building sites containing earthenware with calligraphy, roof tiles, and preserved rice from ancient times.

The fortress remains can be accessed by community bus from Dazaifu Station or Nishitetsu bus from Fukuoka Station, with parking available at Shiouji-kenmin-no-mori.

The castle incorporates sophisticated drainage systems within its stone walls and contains evidence of nine separate gates across its expansive defensive perimeter.
