This is part of the “By Train Across Japan” series. It is the extended version of the ride shown in Chapter Four. Just the train, ma’am, no music, no titles.
I changed seats during the ride, and started shooting out of the other window, because I was getting too many reflections from the glass.
This is a great cab view video of the same trip by @AUNZ RAILFAN: https://www.youtube.com/watch?v=_Hp9rmJyXv4&t=0s
