“Do not step on the threshold” when entering a Japanese-style room. This is one of the basic manners.
The sill is the part that partitions the room with shoji, paper doors. If you step on it, it will be distorted or damaged, and the building will be damaged. To note, Japanese houses were made of wood. This is a practical aspect. In conceptual terms, entering a room beyond the threshold means accepting the room (house) as owner of the house, and accepting that the room is the owner’s space. Something along those lines. Therefore, the act of stepping on the threshold is an act of denying or refusing them, greatly disrespecting the owner. There are various theories, but the above is an example.
What we mentioned was once taught by the elderly in everyday life. It is really interesting because the interpretation etc. differ depends on the region of Japan you’re in. In fact, there are many things that Japanese people don’t know nowadays. There are many cases where various information is unexpectedly exchanged, and the original meaning is buried.
Through this site, we would like to take a chance to introduce Japanese culture to overseas people and re-understand our own culture.
