Speaking of hard working, I took the day off. My wife and I went to Kenko (healthy) land! Kind of a big old place where you pay to get in, then have the use of around ten or so different baths, a number of them being outside in a nicely landscaped garden. The pools have different ingredients, minerals or herbs and such, one has a floating log in it, some wood that is supposed to be good for you, or maybe just for the scent. Most of the pools have a jacuzzi going in them. Also they have saunas and steam baths and some other arrangements like a hot floor room that you can crash out on. Professional massage is available. Other areas with relaxing features covering two stories. Also there are a number of restaurants inside with inexpensive good food and lots of varieties of cold beer or other drink. The place is all super clean and well attended to very professionally run, fresh towels everywhere plus a private little areas to wash up in the main bath area. Ladies come in to check the water temperatures of the baths quite regular, everything is closely monitored. The cold pool has a little waterfall. They give you a locker with a change of leisurely relaxing attire so you can get in and out of the baths if you want to walk around the place and eat or just relax or whatever. Kind of like silk pajamas.
Easily spend a number of hours in there or all day and night if you want. There are also places to sleep. It really is a family atmosphere, people bring their kids. The men and women are segregated bathing, of course nude. After a few hours in there, time takes on a new dimension, the world changes. Super relaxing. Public bathing is down to a fine art in places like that, and everyone respects the manners that are required. No weird stuff like in San Francisco.
Too bad they can't have places like that in other countries, wonder why? I don't go very often, but i do love the place. Everyone inside is cruising around all relaxed and stuff, and all the staff is very courteous. They know how to run such a business, and really the place to go if you are tired or stressed.
By the way, if you have never experienced such public bathing, men usually walk around inside the bath while holding their wash towel over their privates. It isn't like required or anything, but it does help to mostly keep it from being a totally hang loose affair. After a few hours inside though, nothing about nudity really matters.
