Hakone
Hakone sits in the mountains within easy reach of Tokyo, and its hot springs have drawn visitors for generations. Many ryokan here have their own onsen fed by volcanic springs, with views across Lake Ashi towards Mount Fuji on a clear day. An open-air museum in the hills adds an unexpected cultural dimension, its sculptures set against forested slopes. It is the sort of place that rewards slowing down, ideally with an overnight stay rather than a rushed day trip from the capital.
