Is the JR Pass worth it?

Hi everyone,

My sister, bf, and I are traveling to Japan in early September from 9/1-9/14.

We are planning on doing Tokyo > Mt Fuji (Day Trip) > Kyoto > Nara (Day Trip) > Osaka

We were thinking of getting a JR Pass but not using it until we do:

1. Tokyo > Kyoto

2. Kyoto > Osaka

3. Osaka > Tokyo

My question is: is it worth it to get the JR Pass if we're technically only using it for these 3 travel times or is it better/cheaper to get individual tickets for each trip?
