In the middle of Gunma Prefecture, there is an infernal train station : this one takes you straight to the center of the earth! Almost. It is the deepest train station in activity in Japan: here is the Doai Station! The platform looks like the one from a ghost station. There is almost nobody, I only met two families who came down here for the purpose of sightseeing. There is no activity whatsoever, it’s cold, the only bit of life comes from the neon lights.
