14 or 7

Hello all - I'm traveling from 4/2 - 4/15 a total of 14 days but I'm trying to figure out if I can get away with a 7 day pass instead of a 14 (by choosing a leg of my trip to purchase individual tickets). The two big tickets (Tokyo to Kanazawa and Naoshima to Tokyo) seem to demand a 14 day. Below is my itinerary - I would appreciate any tips. My hotels are are booked (which was a challenge since this is such a popular time to visit this wonderful country) so I don't hve the flexibility to change things up. I placed the cost of tickets in yen that i got from Hyperdia. Thanks in advance for your help.

April 2nd: Narita Airport to Tokyo = 1,520
April 5th: Tokyo to Kanazwa = 13, 350
April 7th: Kanazawa to Kyoto = 7,590
April 10th: kyoto to Okayama = 7500
April 11th: Okayama to Uno = 580 (spending two days and nights on Naoshima Island)
April 13th: Uno to Tokyo = 17,140
April 15th: Tokyo to Narita Airport = 1.140
