Not all the restrooms in here in Japan are squeaky clean. Some of the busy Tokyo train station ones are stinky and sticky from urine that splashed on the floor.

Not all the restrooms in here in Japan are squeaky clean. Some of the busy Tokyo train station ones are stinky and sticky from urine that splashed on the floor. I have seen some restrooms where the cleaning crew just comes in with a hose and a brush because there is so much urine on the floor. However, 7-11s and the like tend to have really clean restrooms because you're likely to buy something if you can use the restroom and not leave it in haste.
