7day pass or 14day pass

Hello,
I am planning a 2 week hol in japan in late may and was wondering whether it is cheaper to get a 7 or 14 day pass for the following trips, which can be fit in 7 day pass
- trip to mt fuji - tokyo - osaka - osaka - kyoto - osaka

However, if i take into consideration the other trips below, would it be cheaper to buy the 24 days pass or get 7 seven days pass + individual tickets for the following
- narita airport - central tokyo - transportation in tokyo - osaka - airport - transportation in osaka and kyoto

Thank you
