波賀城史跡公園, Castle ruin park in Shiso, Hyogo, Japan

Haga Castle Historic Park occupies the summit of Shiroyama, a 458-metre independent peak in Kamino, Haga-cho, Shiso. A trail climbs from the foot of the mountain to the castle grounds, where a two-storey yagura and a kabuki-mon gate have been rebuilt. The yagura houses the Haga Castle Learning Museum, and the castle site overlooks the roads linking the Inaba Kaido with Chikusa.

The castle was founded in 1261 by Haga Shichiro and remained under Nakamura clan control through the late Sengoku period. It served as a strategic location during this turbulent military era of Japanese history.

The learning center inside the reconstructed tower displays artifacts and documents explaining medieval Japanese castle construction methods. Visitors can see how defensive structures were designed and adapted to the mountain terrain during this period.

The park is at 2-51 Ueno, Haga-cho, Shiso, on the summit of Castle Mountain at 458 m. From Himeji Station take a Shinki Bus to Yamazaki, change to the Nogi or Hara line, get off at Ueno, then walk 20 minutes or take a taxi for 5 minutes to the top. A trail leads from the foot of the mountain up to the castle grounds.

The two-story reconstructed tower houses the Haga Castle Learning Museum, whose exhibits cover the castle's history. At night the tower and gate are lit up, and the structure can be picked out from the Haga area below. The walk up from Ueno station on the trail to the summit takes about 20 minutes.
