Kaga Province
Maruoka Castle is located on top of a small hill in the plains north of the city of Fukui. The area around the foot of the hill was levelled, and protected by ramparts and a pentagonal-shaped moat. The castle is located on the Hokurikudō highway connecting Kaga Province with Echizen Province, at the juncture of the Mino Kaidō highway connecting inland Mino Province with the Sea of Japan.
