Choosing the best pass

Hello!

I'm planning a trip to Japan in November, and I was wondering which pass would be best for my trip. It's a 12-day trip and I'll be spending most of my time in Tokyo. My itinerary looks pretty much like this:

November 5 (Day 1): Arrival in Tokyo
November 6 (Day 2): Tokyo
November 7 (Day 3): Tokyo
November 8 (Day 4): Tokyo
November 9 (Day 5): Tokyo
November 10 (Day 6): Tokyo
November 11 (Day 7): Arrival in Kyoto
November 12 (Day 8): Kyoto
November 13 (Day 9): Osaka
November 14 (Day 10): Osaka
November 15 (Day 11): Return to Tokyo
November 16 (Day 12): Depart from Tokyo

I was wondering if I should just get a 14-day pass to cover all 12 days or if there was a more cost-effective way to do things. Any and all advice is appreciated.

Thank you in advance!
