Who knows the origin of jokes and names of Japanese kimonos?

The Japanese are bellicose. In ancient times, almost all young men were drafted into the army to fight, and there was no time to get married and have children, so there were fewer and fewer people. At that time, a country formulated a national policy that all men could have sex with any woman at any time and any place to maintain the birth rate. So during the truce, a woman in a certain country got used to the way of "whenever and wherever" and simply went out with a pillow and sheets on her back. Later it became the so-called "kimono". Many women joined the war after being told their surnames "whenever and wherever", so their children appeared in Inoue, Tanaka, Matsushita, Watanabe, Yamaguchi, Noboru takeshita and Kondo.
