She was on a train from Tokyo to Atami in the summer of 1959 when the English travel writer Ethel Mannin "saw what I had read about and been told about but felt unable to accept until I had seen it for myself."
What the mortified Ms. Mannin beheld was the passenger in the seat opposite her stand up, remove his trousers and shirt, and then settle down for the rest of the journey in short underpants and a singlet.
Though the days of blithely peeling off layers of clothing on trains may have gone, shedding garments is what Atami is all about. And, given the countless opportunities it offers to soak in its scalding waters, a stay at this major hot-spring resort in Shizuoka Prefecture presupposes a degree of exposure.
