1 or 2 week pass

Hi folks,

Just wondering if you think it's better to get a 1 or 2 week pass for upcoming trip...
Itinery so far will be:

Kansai airport-Osaka 3rd April 2015
Osaka 4th April
Osaka-Mt Koya 5th April
Mt Koya-Kyoto 6th April
Kyoto 7th April
Kyoto 8th April
Kyoto-shirakawago 9th April
Shirakawago-takayama 10th April (possible shinhotaka ropeway trip)
Takayama-tokyo April 11th
Tokyo April 12th
Tokyo April 13th (possible Mount Fuji trip)
Tokyo April 14th
Tokyo April 15th
Tokyo-narita airport April 16th

Any itinery advice in general and if you think can get away with a 1 week pass say from April 9th-16th? Or if 2 week is best?

Cheers in advance!
