What is the best Option for me cost wise but also flexibility?

Hi there,

I would like to ask what the best option is for me that would help me save as much money as I can while only needing to redeem 2 passes maybe 3, I have a suica and IC card from a previous Japan trip for metro and buses.

My itinerary is as follows

Asahikawa for 3 nights leave morning of 4th day
Sapporo for 3 nights leave morning of 4th day
Hirosaki for 3 nights leave morning of 4th day
Yamadera 2 nights leave morning of 3rd day
Nikko 3 nights leave morning of 4th day
Nagano 2 nights leave morning of 3rd day
Takayama 3 nights leave morning of 4th day
Kawaguchiko 2 nights leave to hike mt fuji for 2 days then return after 1 night on fuji
1 night kawaguchiko leave morning after 1 night
Tokyo 5 nights leave morning of 6th day
Kanazawa 4 nights leave morning of 5th day
Kyoto 3 nights leave evening of 4th day
tokyo 1 day before flying home

basically my trip spans a long distance but requires a few kinks to be worked out. Would it just be easiest to get one 21 day pass and activate for 21 days, have that segment in tokyo and then activate another 7 day pass for the latter end of the trip?

Let me know if you need any more details?!!
