Many Japanese women are embarrassed at the thought of being heard by others during urination[42] (see paruresis). To cover the sound of bodily functions, many women used to flush public toilets continuously while using them, wasting a large amount of water in the process.[42] As education campaigns did not stop this practice, a device was introduced in the 1980s[4] that, after activation, produces the sound of flushing water without the need for actual flushing. A Toto brand name commonly found is the Otohime lit. "Sound Princess," also homophone with a legendary goddess Otohime). This device is now routinely placed in most new public women's rooms, and many older public women's rooms have been upgraded.[42] The Otohime may be either a separate battery-operated device attached to the wall of the toilet, or included in an existing washlet. The device is activated by pressing a button, or by the wave of a hand in front of a motion sensor. When activated, the device creates a loud flushing sound similar to a toilet being flushed. This sound either stops after a preset time or can be halted through a second press on the button. It is estimated that this saves up to 20 liters of water per use.[4] However, some women believe that the Otohime sounds artificial and prefer to use a continuous flushing of the toilet instead of the recorded flush of the Otohime.
