Tourist Pass

Is Yokohama to Nagoya cover by the Alpine
Takayama Matsumoto Area Tourist Pass?

This tourist pass does not cover the fastest railway route,
which is a section of by the Tokaido Shinkansen,
between Shin-Yokohama and Nagoya Stations.

The coverage area of this pass
is more than 200 kilometers away from Yokohama City.

Questions
1. Overnight Gero or Takayama for Day 1?
2. Any suggestions to make this itinerary better using Tourist Pass?

Hmm..., your time for Matsumoto sounds too short.
Depending on your destinations, your now-planned trips may be rushed.

You have only five days.
The whole Tateyama Kurobe Alpine Route plus other five or six areas
may well be to much to explore in such a short time span.
I would set one no-going-out day
for a rest or a possible delay due to circumstances such as weather.

Gero can be a good choice to stay overnight;
lodgment facilities may not be located near a JR station,
so please make sure to consider in advance the accessibility.

Kiso Valley? Mainly Magome and Tsumago?
