Is 7 day JR pass worth?

Hi, just if 7 day JR pass is worth for the following itinerary?

We are a family of four adults, travelling to Japan in early July for 10 days.

Our itinerary planned is:

Arrive - Haneda
Day 1, 2, 3 - Tokyo East and West visit
Day 4 - Mt Fuji (From Shinjuku to Kawaguchiko and return)
Day 5 - Tokyo to Osaka
Day 6 - Osaka to Hiroshima and return
Day 7 - Osaka to Kyoto return
Day 8 - Osaka
Day 9 - Travel to Haneda fly home.

Please advise what is the best pass for travel around Tokyo, for about 3 days, that covers trains, and buses.
Local itinerary - Toyo, Koto City - Shinjuku, Toyo Koto City - Shibuya, Toyo Koto City - Tokyo Station

Thank you - SJSJ
