The legend of the "Kodakara no Yu" (Bath of Child-Treasure) is said to be that "women who are troubled with infertility will be blessed with children if they bathe in it." In the Edo period, there was a professional bather who washed the bodies of customers. There is a theory that in the Kodakara no Yu baths scattered throughout the country, "the bather had sex with the female customers, ejaculated inside them, and made them pregnant." ...This time, we interviewed three couples who were troubled with infertility at a unique beauty salon that is rumored to be blessed with children, and found out about the services that were given to them.
