8 days in tokyo

Hi Daniel,
I will like to make some changes on my iterary , instead of going to kyoto i have decided to stay around tokyo but travel a bit out of tokyo.
Will like your advise if i should purchase the 7 days JR pass.

1. Arrive tokyo Narita airport then to kuramae station spend time around tokyo city
   2.travel to disneysea
   3.travel to mt fuji
   4.travel to mt ta
   5.travel to kumakura
   6.travel to mt takao
   7.travel within tokyo
   8.kuramae to narita airport

As I think going to kyoto is a bit rush for me, i have decided to change to the above iterary , but still unsure whether I require to purchase the
7days JR pass hope you can advise.

Thank you and have a nice weekend.

Regards,
Sariz
