7 vs 14 days japan rail pass

Hi Daniel-san,

we will be visiting japan as a couple in may for 14 days with the itinerary below,

1 day arrival in haneda airport
3 days in tokyo city
1 day in nara
1 day in fujigoko for the shibazakura festival
2 days in takayama
1 day in shirakawa
1 day in kanazawa
2 days in kyoto city
1 day in nara
2 days in osaka
departure from osaka kansai airport

with this itinerary, which pass will be most suitable? 7 or 14 days? also I notice that they have other passes available for tours such as the Osaka Amazing Pass and All Nikko Pass.

with so many options available to compare, with I am finding it a little difficult to decide and I need your advice.

thanks in advance
