15 nights - itinerary check

Hi there

We are travelling to Japan in April and our planned itinerary is as follows (arriving in Tokyo on Sunday 2 April):

• 2 nights Tokyo
• 3 nights Kyoto
• 3 nights Kumano Kudo trek - travelling to/from Tanabe
• 1 night Osaka (travelling from Tanabe to Osaka)
• 1 night Kagaonsen and spend day in Kanazawa
• 2 nights Near Takayama (Sakakami is nearest station)
• 3 nights Tokyo (with hopefully a day trip to Mt Fuji)

Is this itinerary viable and will we get good use out of the rail pass?

Many thanks!
