Tokyo - Nagoya - Kyoto - Nagoya

Hello!
I will on the 28th of April to tokyo and stay close to the Zoo in Taito Ueno.Vou to walk there for 3 days and want to visit the zoo, the park Ueno, Asakusa, tokyo city view, Akihabara, Odaiba, top seaside, Tokyo Tower, Roppongi Hills, Shinjuku and Shibuya.
Then I will spend a day in Nagoya and then I will spend 02 days in Kyoto returning to Nagoya on 05 May to Nagoya where I'll be for another 6 days.
I wonder if this route compensates for JRPass buy or not. I thought about buying the 7 days for sightseeing in Tokyo going to Kyoto and back to Nagoya and then walk with other means of transport in Nagoya.

Thank you
