This is my itinerary. Is the JR pass worth it?

Hello - I have tried working out whether the JR pass is worth buying based on my itinerary below but it seems close!
Can anyone help? TIA

Mar 30 Tokyo - Osaka
Mar 31 Osaka - Kiitanabe
(Hiking the Kumano Koto) 06 April Kiikatsuura - Kyoto
Kyoto - Hiroshima Hiroshima - Kyoto Kyoto - Himeji Himeji - Kyoto Kyoto - Nara Nara - Kyoto 11 April Kyoto - Tokyo
11 April Tokyo-  Narita

I'm guessing I'd either get a 7-day pass to cover the 06 -11 April journeys OR a 14-day pass for the whole lot.

Thank you!
