Do I need a 14D JR Pass?

Hello. I wonder do I need a 14D pass for my trip and am I over ambitious with the itinerary.

D1 - Osaka
D2 - Osaka - Himeji - Osaka
D3 - Osaka - Hiroshima - Miyajima - Hiroshima
D4 - Hiroshima - Kyoto
D5 - Kyoto - Nara - Kyoto
D6 - Kyoto - Kanazawa
D7 - Kanazawa - Kusatsu
D8 - Kusatsu - Tokyo
D9 - Tokyo - Ibaraki
D10 - Ibaraki - Tokyo
D11 - D13 - Tokyo

Or is there an alternative itinerary or pass I should go for?

Thanks.
