@SchultzD As far as I know in Japan there is no law against polygamous relationships outside of marriage (tho it wouldn't surprise me if some places like Toyko had local laws against it). But with their culture it would probably be social and maybe career suicide when people find out. The Japanese in general have a nasty habit of being judgmental and ostracizing people who do things that are considered improper or dishonorable by society even if it's not illegal.
