hello

Will be travelling to Japan this March 2015 with my 11 year old son. We will be travelling for 2 weeks.

Our itinerary:
Mar 2 - arriving Tokyo Narita then travelling to Hakuba,

Mar 2 - 6 , planning to go to Hakuba for skiing
mar 6 overnight in Tokyo.
mar 7 - to Nagoya (but we'd love to drop by Mt Fuji on the way to Nagoya for photo and sight seeing) any suggestion on where to go to get a glimpse of Mt Fuji? Then overnight in Nagoya.
mar 8 - travel to Kyoto. Overnight stay.
mar 9-11 - travel to Osaka /stay for 2 days.
Mar 11-12 - Travel to hiroshima/overnight stay
Mar 12-15 - travel back to Tokyo
Mar 15 - Leave Japan

This i just a tentative plan. Any suggestion to change my itinerary for a better plan will be much appreciated. But Mar 2-6 is reserved for my skiing trip.

Next question, can you please suggest the economical and fastest way to travel to the above itinerary? Do you suggest JR pass? Dont mind taking the bullet train as it will be a good experience for me and my son.

Any suggestion for a cost effective travel plan for transportation?

Thank you for your time
