Hakone (ryokan kaiseki and onsen) ★ 4.6
Hakone in Kanagawa is the onsen ryokan town under Mount Fuji where the kaiseki dinner is the main event. Eat the multi-course meal in yukata before the bath.
Tip: Book a ryokan with two meals included; the kaiseki is the trip. Day-trip via Romance Car if overnight is too much.
