JR Pass yes or no?

Hello, unfortunately I couldn't find a good answer to my question so far, so I'll try here.

We are landing in Osaka Kansai on November 2, staying there until November 5. On November 5 we would like to make a day trip to Hiroshima and from there on to Kyoto.
In Kyoto we will stay from November 5 to November 9 with a day trip to Nara.
From Kyoto we will continue to Fujikawaguchiko on November 9 and stay there until November 11.
On November 11, we will continue from Fujikawaguchiko to Tokyo until November 17. On November 17 we will depart from Narita.

Is the JR Pass at the old price worth it for us?

Thanks in advance!

Kind regards,
Mia
