advice on itinerary.

Hi there, I am traveling with my wife and kids. We are 6 people in total , all kids are 13 and older. We will be in japan landing on December 22, 2025 at Narita airport and departing from Narita airport on January 4th, 2026. Our itinterary has us in Tokyo until december 26th when we will travel to Kanazawa Ishikawa. We will be there until Dec 27 when we will travel to Hakuba by taking a train to Itoigawa and then a local train to Minami Otari. Then on Dec 30th we will travel to Kyoto. On January 1st we travel to Osaka. And finally we will go back to Tokyo on January 3rd. Then on January 4th we go back to Narita airport for departures. Does it make sense for us to purchase the 14 day pass or are we better off just buying the tickets individually ? thanks kindly Dave
