Family Travel

Hello - we are flying into Haneda Tokyo and will need to catch the train from Haneda to Ginza (which is where our hotel is), we will then be in Tokyo for 2 days before going to Kyoto for 3 days, we will then return to Tokyo and depart for Hakuba on the Shinkansen to the snow for a week. We will return to Tokyo via the Shinkansen and spend another day in Tokyo before catching the train back to the airport.
Is a 14 day JR pass the best option for us, we are a family of 3. Will the JR pass cover all the different train journey types that we have as well??
Thankyou
