Why don't Japanese toilets stink?

Because the toilet and bathing in Japanese families are completely separated, if the house area is too small and there is no bathing area, you can also go directly to the public bath.

Most families in Japan use smart toilets and floor drains. When you go to the toilet, a small stream of water washes it clean. There is also a flushing function after going to the toilet, which can achieve the function of deodorization and sterilization. Therefore, many people in China like to buy toilets to take back when they travel to Japan.

Japan is a small place, and many families' toilets are not ventilated, so some aromatic products will be used to deodorize.

And because most people eat in the toilet, the smell affects others, and many places explicitly prohibit:

Toilets in Japan are really clean. There will always be people eating in the toilets and surfing the Internet, which will affect the normal use of others. Therefore, many public toilets will be affixed with warnings of "No Eating". The most important thing is to worry that your taste will affect other people who use the toilet normally. After all, this is a public toilet, not a private toilet at home.

The way Japanese eat in the toilet may be difficult to understand, but we should respect the local warnings and don't try it even if it is clean. Just try the local toilet restaurant.
