Meaning 'deep Hida hot springs', Okuhida Onsen-gō – comprising the villages of Hirayu Onsen, Fukuji Onsen, Shin-Hirayu Onsen, Tochio Onsen and Shin-Hotaka Onsen – has a tough battle with Shirakawa-gō for being the jewel in Hida's crown. Certainly it's where you'll find some of the loveliest onsen ryokan (traditional hot-spring inns) and alpine scenery in all of Japan.
It's impossible to compare the two contenders, and you'd be well advised to visit as much of the Hida Region as you can, but if time is limited it's well worth taking the journey deep into the mountains to spend a tranquil evening here. Of the five villages, Hirayu, Fukuji and Shin-Hotaka Onsen have the most to offer visitors, by way of their wonderful ryokan. If the weather's clear, take a ride on the Shin-Hotaka Ropeway.
