This beverage commercial pulls out the trope of the-only-passenger-left-at-the-out-of-the-way-train-station-is-a-high-school-girl, first seen here. Miharashidai station really is out of the way, on a branch line connecting Takamori to Kunamoto in central Kyushu where, I guess, they also have winter. The combination of high school girl and endangered branch line evokes a sense of the ephemeral quality of things, and can be used to sell bottled tea. Watch.
My complaint: if the Annapolis Valley were in Japan I'm pretty certain there would have been a morning train from Kingston Station to West Kings DHS when I was going to high school. The tracks ran right past my door and the school.
