Ishigaki-yama Ichiya-jo: Witness the Illusionary Castle of Hideyoshi Guide
Journey back in time and explore the strategic brilliance of Ishigaki-yama Ichiya-jo Castle Site, a fascinating historical landmark overlooking Odawara. This "one-night castle," as it's often called, played a pivotal role in Toyotomi Hideyoshi's siege of Odawara Castle in 1590. While not a traditional castle in the sense of towering keeps and fortified walls, Ishigaki-yama Ichiya-jo offers stunning panoramic views and a glimpse into the cunning tactics of a legendary warlord. The story of Ishigaki-yama Ichiya-jo is one of deception and psychological warfare. In 1590, Toyotomi Hideyoshi, aiming to conquer the Hojo clan who controlled Odawara Castle, ordered the construction of a castle on Ishigaki-yama (Mount Ishigaki) in secret. Using the dense forest as cover, his troops worked tirelessly, and within a few months, a fully functional castle appeared seemingly overnight. This sudden appearance demoralized the Hojo defenders within Odawara Castle, contributing to their eventual surrender. The name "Ichiya-jo" (one-night castle) is a bit of a misnomer, as it took months to build, but the illusion of its rapid construction was key to its success. Today, visitors can explore the remains of the castle site, including reconstructed walls and gates. The main draw, however, is the breathtaking panoramic view of Odawara Castle, Sagami Bay, and even Mount Fuji on a clear day. It's a fantastic spot for photography and appreciating the strategic importance of the location. While there aren't specific culinary traditions directly tied to the castle site, you can find plenty of delicious food options in nearby Odawara, including fresh seafood and local specialties.
