The castle is historically known as 'Uru-jo' or 'Wet Castle' because its wells were famously never known to dry up.
It served as the administrative center for the Kururi Domain during the Edo period under the Kuroda and Okubo clans.
The castle grounds contain a dedicated 'Water Well' monument commemorating the legendary abundant water source.
The current reconstruction is a ferro-concrete replica rather than an original wooden structure.
The surrounding landscape is part of the Kimitsu-city designated historic site area.
Kururi Castle is a reconstructed hilltop fortress located in the Boso Peninsula of Chiba Prefecture. Originally built in the Muromachi period, the current three-story donjon was reconstructed in 1979 to serve as a local history museum. It is situated on a steep ridge, approximately 120 meters above sea level. The site includes remnants of the original earthworks, dry moats, and stone foundations of the Edo-period stronghold. The museum displays feudal artifacts, weaponry, and documents related to the Takeda and Satomi clans who governed the region. It is one of the few castles in Japan accessible by a moderate hiking trail through a forest of Japanese cedars.
The observation deck atop the reconstructed donjon provides a panoramic view of the surrounding Boso mountains.
Wear sturdy walking shoes as the path from the parking area to the hilltop involves a steep incline.
Bring insect repellent during the summer months due to the dense forest canopy.
Visit the small information kiosk at the base of the hill for maps of the remaining earthen fortifications.
Do not attempt the hike if you have mobility issues, as the path is unpaved and features uneven elevation.
Closed on Mondays and during the New Year holiday period.
No specific dress code, though quiet behavior is expected inside the museum galleries.
