What pass would be ideal for me?

Hi,
I'm travelling to Japan on 2/4 to Tokyo and from there:
02/4 Tokyo
05/4 Nagoya Day Trip
07/4 Mt Fuji (possibly with a tour guide)
08/4 Stay at Osaka
10/4 Nara & Kyoto Day trip
11-14/4 Tokyo

What would be the best ticket for me? Would it be better if i paid for Nagoya separately and buy a pass from 08/04 to cover going to Osaka, Kyoto and back to Tokyo?

Thanks in advance!
