The construction of the castle began in 1601, under Kinoshita Nobutoshi's orders, when he was transferred to Hiji from Himeji.
The castle was designed by Nobutoshi's brother-in-law, Hosokawa Tadaoki.
[1] It held a strategic location, as it overlooked Beppu Bay.
The castle was destroyed after the Hiji Domain was abolished during the Meiji era.
[2] Today, the castle's ruins (all that remains are the stone walls and the Sumi yagura) are a park, though Hiji Elementary School is also located on the grounds.
