Is it worth buying a pass for this 2 week itinerary?

Hi! We're going to Japan in 2 weeks and this is our itinerary:

• 3 days in Tokyo (one day trip to Nikko)
• 3 days in Kyoto (one day trip to Nara)
• 2 days in Osaka
• 2 days in Kinosaki Onsen
• 2 days in Tokyo (one day trip to Hakone)

I think we will need to use transportation also visiting Tokyo.

Is it worth buying a JR pass?

Thank you for your help!
