Is this plan advisable.
02 Nov. Stay a night at Toyama

04 Nov - Proceed to Tokyo.

The trip from Kawaguchiko to Toyama is even more complicated and time-consuming than the trip from Kawaguchiko to Shinano-Omachi. That is why I recommend to travel the Alpine Route from east to west. Furthermore, the western end of the Alpine Route is prone to road closures during November. If you approach from the east, you could still see the Alpine Route even if the approach from Toyama is closed. That is another advantage of traveling from east to west.
