The difference between American vs. Japanese restrooms might be explained by cost. It’s probably cheaper to buy stalls with partial dividers. If I owned a business, I would want to install the type you described - with dividers from the floor to the ceiling and without gaps in the doors - but it might be too expensive.
I’ll tell you, I don’t like sending my young sons into public men’s rooms to use urinals that are open for everyone to see. Urinals should be enclosed, too. (Between the germs and this weird stuff going on, I worry about sending them in there at all, as do many other parents.)
Personally, I prefer the “family” restrooms. The whole family goes in and locks the door to outsiders. There’s a toilet, a sink, a diaper changing station, in one private room.
P.S. We don’t seem to have the same problems in the women’s rooms, at least as far as I’ve noticed, anyway.
Note: In the family restrooms, the toilet is enclosed in a stall, too.
Good suggestions and thoughts. Take care, Good night.
Unfortunately, that's because we haven't enforced codes of proper social conduct. Now we have to worry about the person across the table, or in this case, the stall.
I prefer open spaces, with clear fields of fire.
I had to spoil things but not every person in a dress with makeup on is a woman.
