Oka Castle Ruins
Presumed to be founded in 1185, Oka Castle eventually became the main fort of the Oka Domain in 1594. It was often referred as "Gagyu Castle" for its appearance resembling a cow lying down.
Atop the castle provides a stunning view of the surrounding castle town as well as Mt. Kuju and the Kuju mountain range.
Selected for Japan's Top 100 Cherry Blossom Spots, the castle premises is filled with many cherry trees.
Oka Castle Cherry Blossom Festival featuring a reenactment of the daimyo procession takes place here in early April.
