Hi there!
Here are some answers to your questions:
May I use the JR Pass 7 Days from Osaka to Nagoya without additional charges ?
Yes - you can get the Hikari shinkansen from Osaka to Nagoya. Here's a sample itinerary.
How many times I can use the JR Pass 7 days per days ?
As many times you want! There is no limit of number of uses.
Can I use the JR Pass from Nagoya to MT Fuji ? Any suggestion or guidelines or advice.
Yes, you have 2 options for Mt Fuji:
1) Hakone
2) Kawaguchiko
Kawaguchiko is the main starting point for hiking up, and is a lovely location to view the mountain from. Hakone is an onsen area with great views of Mt Fuji.
For Hakone, you can use the JR Pass to get as far as Odawara (sample itinerary. From here you must get the non-JR Odakyu train up to Hakone area. I reccomend the Hakone free pass for this.
For Kawaguchiko, you can use the JR Pass to get as far as Otsuki. From here you will need to get the non-JR line to Kawaguchiko.
After Mt.Fuji, I will go back to Nagoya stay a night then next day I will go back to Osaka, Can I use the same JR Pass without additional Charges ?
Yes, this will be no problem.
I will stay at Osaka 5 days and everyday I will visit different place like Kyoto, Kobe, Nara,Osaka City, May I know How many times I can use the JR Pass ?
The JR Pass is valid for all of these trips, so you can cover them all on 1 ticket.
How much cost from Osaka to Kansai airport ? Due to My 7 days JR pass valid until 23 March 2012 and my fight is 24 March 2012 night.
Here is a sample itinerary from Osaka to Kansai. The cost of this trip will be ¥1560.
You can look up train timetables and costs at the Hyperdia travel planning website and learn how to use Hyperdia for Japan Rail Pass holders through our video blog.
Hope this helps!
