Here is random “WTF Japan?” for you: a Japanese court has indirectly endorsed adultery for business purposes if the sex is predicated on securing future club patronage by the customer:

Some experts said the ruling effectively endorsed adultery, as long as the third party – in this case the hostess – was motivated by financial gain.

The judge, Masamitsu Shiseki, said the hostess had slept with the customer only to secure his continued patronage of the club she runs in the capital’s Ginza shopping and entertainment district.

High-class hostess clubs charge customers large sums to spend time drinking, chatting and singing karaoke in the company of female staff, but they do not offer sexual services.

Shiseki said the hostess’s actions were more akin to prostitution than an affair, and dismissed the wife’s ¥4m (£20,860) claim for emotional distress.

The wife was asking for ¥4m, which is merely $33,000. There are no million-dollar judgments in Japan, unlike the crazy US, where people try to use the court system as some mock “get rich quick” scheme.

This type of legal opinion is likely only to be found in Japan. The rest of the world has already caught up with modern societal norms around adultery.
