Also known as Funai Castle, Oita Castle was constructed by Takenaka Shigetoshi who took over after Fukuhara Naotaka, the brother-in-law of Ishida Mitsunari who served under Toyotomi Hideyoshi.
The original moat around the Honmaru main tower is now filled in, as the ground today serves as Oita Castle Ruin Park.
The Park is also known as a popular cherry blossom viewing spot where over 70 trees of beautiful Yoshino cherry flowers come into full bloom.
