I don't have the patience to listen to that long,windy BS explanation.
"The House of the Rising Sun" was a pop song based on the Japanese Imperial Family because that IF I REMEMBER CORRECTLY,that was the name of their "House".
A "House" in this context means it is the equivalent of a Clan or a group of people who are dedicated to being followers of the clan leader as well as related to the Royal Family in some way.
It is also a religious thing,akin to the Catholic Church for Italians.
Of course,the Japanese and other Asians have and always have had a different outlook on morality than westerners,and this is maybe most evident when it comes to sex. They see sex as a natural desire and activity,and nothing to be ashamed of. I will even go so far as to say that in at least some Japanese families I knew in the 60's,they were even proud of having a daughter who was a "Business girl".
Of course,in the song,"The House of the Rising Sun" is a whorehouse in New Orleans and the title was probably chosen because it was mysterious as well as sexy sounding,and the women are called Whores in the US,not "business girls".
