As a Japanese saying puts it: Suezen kuwanu wa otoko no haji (It is shame for a man not to eat a feast placed before him).
In other words, any real Japanese man would never turn down a sexual offer from an attractive female — whether he’s married or not. Adultery and infidelity are time-honored Japanese traditions — for the nation’s men.
...
So, Japan’s men aren’t the only ones who may have something on the side — though even that works to their advantage, too, as the penchant for hitozuma (sleeping with other people’s wives) is no rare thing. In fact as a form of schadenfreude, it’s succinctly expressed in the everyday saying, Hito no fukō wa mitsu no aji (The misfortune of others is a taste of honey).
