Must be time for another post about Japanese toilets

Caring about toilet noise: from feudal-era urn to 21st century gadget

This article suggests that Japanese sensitivity about the sounds people make when using a toilet has a long history. You've probably heard before:

most ladies’ rooms in the country’s department stores and office buildings are equipped with a device commonly known as ‘‘Otohime’’—originally the brand name of a product developed by Toto Ltd—which emits the simulated sound of a toilet flushing.

The rest of the article contains some phrases that you are unlikely to hear again. Ever. I'll put them in bold:

Shigenori Yamaji, an expert on toilet culture and researcher at Osaka University of Tourism’s Institute of Tourism Studies, agreed that being embarrassed by the thought of other people hearing such sounds in the lavatory seems peculiar to Japan.

According to Yamaji, this particular sensibility can be traced back to at least the 19th century, a time of feudalism in Japan, as the residence of a wealthy family in Yakage that also served as a designated inn for dignitaries was equipped with an urn traditionally called ‘‘Otokeshi-no Tsubo’’ (Urn for Covering the Sound).

The urn, now kept in storage at Yakage Folk Museum and expected to be put on display there in the near future, has a water outlet in the shape of a dragon. A curator said the urn was originally placed on a platform near the restroom, which was exclusively for the high-ranking guests of the inn and not for family members or servants.

When a guest wanted to use the room, it is thought that his attendant would be standing by to lift the plug on the urn and let the water out from the dragon’s mouth to cover the sound of the nobleman urinating, Yamaji said...

But some are critical of the custom. ‘‘I think the Japanese sometimes read too much between the lines,’’ said a housewife in her 30s in Chiba Prefecture.

‘‘My own excretory sounds never make me embarrassed. It’s much more embarrassing to put on makeup on the train,’’ said a dance instructor in her 50s in the same prefecture.
