Specificly days 6 to 9 are a bit unknown. I wanted to visit the Snow Corridor from the Toyama side as that can be reserved in advance.

This year the Ski season stopped around on the 5th of may. And we would be visiting on the 1st of may. So with some luck we might be able to do that. Otherwise there would be plenty of other things to do nearby.
