Japanese locker/changing rooms also have the infamous 70-year-old cleaning woman. (They must be scheming with the Czechs.) I'd love to see the look on everybody's faces if the cleaning lady appeared one day and was some sensual 24-year-old instead. :biggrin1: In talking to friends, I think most younger people ignore them or feel slightly uncomfortable, but it makes the older generations feel at home, as if their wives were there picking up after them.
There is a LOT more personal hygiene that goes on in Japanese locker rooms (especially at a public bath/hot spring locker rooms), like ear cleaning, shaving, nail clipping, etc.
Since the Japanese are all naked around each other since birth and childhood, there is little to no "naked = sexual turn-on" mentality that seems to be more prevalent in the U.S. It's no big deal to go out drinking with your buddies from work, then all end up in naked a bath together by the end of the night - nothing sexual about it at all. Whether it be in the locker room or in the bath, being naked is a time when they can let their guard down a bit and not have to follow the strict behavioral norms expected of a rigidly hierarchical culture/society.
