There's much we can learn about the past from studying old ruins. Take a trip back through history and ponder times gone by at Yamanaka Castle.
You'll be spoiled for sightseeing choice when spending time in Mishima. Yamanaka Castle is an ideal place to start here, but there are loads of other fine sights to discover. Lake Ashi, Hakone Shrine, and Mishima Sky Walk are close to the once-important structure and will top off your day nicely.
