Is it worth getting a JR pass and for how long?

Hi,

I am travelling in Japan from 25th April - 8th May this year and wanted to check if it was worth getting a 7 day or 14 day JR pass or just buying individually with the itinerary as below? (The query also involves local travel at each place).

25th April -Tokyo (1 night in Tokyo)

26th April - Travel from Tokyo to Kanazawa (1 night in Kanazawa)

27th April - Travel from Kanazawa to Takayama (day trip out from Takayama to Shirakawa go during this time) (2 nights in Takayama)

29th April Takayama - Osaka (3 nights in Osaka with travel between Osaka/Kyoto/Nara)

2nd May - Osaka - Tokyo (in Tokyo until flight on 8th May) - day trips to Hakone/Nikko/Enoshima/Yokohama/Asakusa

Happy for any help!
