Once they get married, Japanese women will do pretty much everything they want, because age - looming on the horizon like Godzilla lurching closer with each passing year - justifies every misdemeanor and betrayal. Infidelity is fine because, as Rinko put it, "I need something to look back on in my old age when no one wants me anymore." That pretty much sums up the morals of the Japanese woman for you.
