About this event
In Yoshida Town, Shizuoka Prefecture, an event offering free admission to the Koyama Castle Observation Deck will be held in honor of Prefectural Citizens' Day. Take this opportunity to enjoy the view from the Koyama Castle Observation Deck, located in Nomanjiyama Park, where the flatland-mountain castle of Takeda Shingen is said to have been built during the Sengoku period. From the observation deck with a corridor, a 360-degree panoramic view unfolds, and weather permitting, you can look out over Suruga Bay, the Makinohara Plateau, and even Mount Fuji and the Alps mountain ranges. It will be a day to savor magnificent scenery while feeling history alongside archaeological remains such as triple moats that recall the atmosphere of those times.
