which took place mostly in the rural areas of Japan, in which, at night, a man could go to the room of a virgin girl of his choice and invite her for intercourse. This matchmaking was a type of matchmaking, when the matter reached a “consensus”, then a long term relationship was established. In case of failure, this man also had to quietly leave for another girl’s house
Yes, one important point is that the man used to enter the girl’s house completely naked so that the girl’s parents would not kill the man entering the house thinking that he was raping or a thief because he was naked. This allowed the parents to know that it was not a thief or a rapist, and the naked man also got an excuse that he had entered the house with the intention of hiding his body. The parents of the girls were supporters of this tradition. They even deliberately left the doors of the house open and tied the dogs
Finally, one thing must be clarified that with the passage of time, people also add many things which were not manifested in reality, therefore men entering houses naked can also be an exaggeration.
