For D6 - D8: Is there any recommended travel pass?
Or any other areas recommended to cover for 1st timer to Chubu areas?

Looking forward your sharing and guidance. Many thanks

Hi!

Takayama colour is quite a bit earlier in my experience, a few years back we had really nice colour there at the very beginning of November, in fact a lot of the higher elevations were already brown.

Other than that comment which might or might not be useful, I think the time at Nagoya is a bit long, I wouldnt spend more than a night there. If it was a weekend, I would stay at Nakatsugawa and then do the Tsumago to Magome walk, or maybe go further up the line and stay at Kiso Fukushima. Otherwise I would consider a night at Hikone which is really pretty, it gets very nice autumn colours in the castle area toward the end of November.

I would stay more time in Kanazawa and no time in Toyama unless you have a very specific interest in Toyama
Also did you consider Kurobe gorge?
