Osaka/Kyoto/Tokyo Trip

Hi There

We are 4 guys planning to visit Japan in October
We will arrive at Kansai airport in the evening. Stay 3 nights in Osaka and visit some attractions
From Osaka we will travel to Kyoto for a 2 night stay. Here we will at least visit four attractions.
From Kyoto we will travel to Tokyo (Akasaka) for a 6 night stay.
We will mostly be in and around Tokyo. Two visits to the International Tokyo stadium and also a visit to a Onsen bath.
From Tokyo we will head home via Haneda airport

I don't really think a 7 day JR pass for our last 7 days will be worth it?
What do you think

Thanks
Merv
