Which Pass Suits Me Best?

Hello there! :)

I have the following travels:

Dec 11 - Narita to Tokyo
Dec 18 - Tokyo to Kyoto
Dec 24 - Kyoto to Hiroshima
Dec 25 - Hiroshima to Miyajima
Dec 26 - Miyajima to Osaka
Dec 30 - Osaka to Tokyo
Jan 2 - Day trip to Fuji/Hakone
Jan 4 - Tokyo to Narita

Which Pass would you recommend? And when do you recommend I activate it?

• On another note, how many days would you recommend in Hiroshima - 1 or 2?

Thank you very much. :)
