Japanese toilet company, TOTO has released Otohime since 1980s.
Otohime is one of the toilet accessories attached to the wall of the toilet.
Otohime meaning sound princess since makes a loud flushing sound when activated.
Because many Japanese women are embarrassed at the thought being heard by others when using the toilet.
In order to cover the noise, they keep using a large amount of flushing water. It results water resources wasted and money inefficiency. For the reason, Otohime has been developed to prevent the bad practice.
On the other hand, you probably don’t see Otohime in a toilet for men.
Because men don’t care even if somebody stands at the right next to them during their peeing.
There is an interesting story.
Toilet cleaners said that public toilets for women tend to be dirtier than public toilets for men.
It is because women have a lot of works such as make-up or chat.
However, it is interesting that they tend to care about their own situation more than something around them.
