Yamanaka Castle

Overview

Yamanaka Castle is a mountain castle in Mishima City, Shizuoka Prefecture, built by the Hojo clan. One of the Hakone Ten Castles, it played a vital role as a supporting castle to Odawara Castle. Though abandoned after the fall of the Hojo clan, it retains much of the unique architectural style of Hojo castles, making it a compelling destination for history enthusiasts. Construction began during the Eiroku period (1558-1570) under Hojo Ujiyasu. Strategically built to incorporate the Tokaido Road, it served as the most important western defense point for Odawara Castle. As relations with Toyotomi Hideyoshi worsened during Hojo Ujimasa's reign, the castle underwent renovations to strengthen its defenses, but these were ultimately incomplete when the Toyotomi army arrived. During the Odawara Campaign of 1590 (Tensho 18), a 68,000-strong army led by Toyotomi Hidetsugu attacked Yamanaka Castle, capturing it in just half a day. The castle was subsequently abandoned. The remaining structures of Yamanaka Castle include wide 'shoji-bori' (moat), small parapets on the breastworks, a plan linking lines and bastions, and enclosures that don't adhere to flat surfaces. These features showcase the castle's design principles, prioritizing concentrated firearm deployment and maximized firepower. Selected as one of Japan's 100 Best Castles in 2006, it's now a well-maintained park, offering a glimpse into its past. From the castle ruins, you can enjoy breathtaking panoramic views of Suruga Bay and Mount Fuji. When visiting Yamanaka Castle, take a moment to reflect on its history and revel in the magnificent scenery.
