7 Day Pass or No?

Hello,
Many thanks in advance for your response. Planning a trip for March 25-April1. Land in Osaka on the morning of 25th - stay 1 night
26th - 27th: to Fussa to visit/stay with friends, to Tokyo, back and forth to Fussa as home base
28th: to either Hakone or Kawaguchiko,
29th- 30th: to Kyoto,
31st: to Osaka and a day trip to Nara
Fly out Osaka on 1st.
Using the itinerary planner it didn't seem like it made sense to buy the pass, but I'm not sure. I also was having difficulty figuring out travel to the Mt. Fuji area, either Hakone or Kawaguchiko (Kawaguchiko is my preference, but I understand it's not as easy to travel to?).
Obviously given our short visit, I'd like to minimize travel time, but also be covered with all areas of transportation.
Best,
Emily
