Which pass should I buy

Hello,

I am planning to go to Japan and will travel from one city to another.
Below is my route:
Day 1 : Arrive at KIX and go to Kyoto
Day 2-4 : Kyoto
Day 5 : Kyoto - Tokyo
Day 6 : Tokyo - Shizuoka
Day 7 : Shizuoka - Mishima - Kawaguchiko
Day 8-9 : Kawaguchiko
Day 10 : Kawaguchiko - Tokyo
Day 11-14 : Tokyo

Kindly advise which pass should I buy? Is it JR Pass or is there any cheaper pass that will serve well with my above itinerary?

Thank you so much.
