I was watching TV with the lovely Kazuyo this morning over breakfast and there was a broadcast showing this area.
This is a pretty nicely made video. You need to listen carefully to the audio to catch everything, but I am really encouraged to hear a non-native speaker of English do such a good job. Makes me worry if I one day decide to make a video with my Japanese! Not yet, but maybe one day.
One of the cool things I liked best was the cable car you need to take to get to the top. And sitting in an onsen is simply divine. I love that. So, give it a look, and for a really off the beaten path Japan experience make your way out here.
