Explore the historic Iwadono Castle Ruins, located in Otsuki City, Yamanashi Prefecture. This mountain castle, once controlled by the Oyamada clan under Takeda Shingen, offers a challenging 40-minute hike from Otsuki Station. Discover remnants of fortifications like moats and baileys, though they are not heavily maintained. The steep climb rewards visitors with panoramic views of Otsuki and, on clear days, Mount Fuji. Be aware that some areas may be closed due to landslides. Wear appropriate footwear and prepare for a strenuous hike, especially during warmer months.
