Which is the best pass for us?

Hi we are spending 13 days in Japan end of october, beginning of November. We are a family of 4 ( 2 adults, 2 children: 11yr old and 4yr old)

Day 1 ( arrive Tokyo Haneda airport, staying central tokyo.
Day 5 tokyo- Kyoto
whilst based in Kyoto, we plan to do day trips to Osaka, Nara
Day 9: Kyoto-Hiroshima
plan to take ferry to mirajima island
day 12: Hiroshima-Tokyo
Day 13: tokyo to narita airport

Can we please have advice on the best pass, get the 7 day pass and activate at day 5? Just get the 14 day pass? or are individual tickets the best way to go.

Thanks for your time, much appreciated.
