Suggested Pass/Purchase Date for Nagasaki to Tokyo Trip

Hello!

I was wondering what would be the recommended pass for my trip/itinerary. My trip will have me arriving in the evening in Nagasaki on 11/29 visiting multiple prefectures/cities/places as I make my way to Tokyo where I will spend the tail end of my trip. I fly out later in the evening on 12/20 from Hanada Airport.

Below is a list of the locations I will be visiting/traveling through by train. Also when would be the best date to purchase my pass in order to pay the old price before the increase on September 30th (NA) / October 1st (Japan)? I think depending on the suggested pass would determine when I would want to place my order?

Day 1: Hanada Airport (Afternoon) -> Nagasaki Airport (Evening) -> Nagasaki Downtown Area (Evening/Night)
