A court ruled in Japan recently that extra marital affairs are okay if they are for business purposes. 

The Japan Times reported on a recent case which describes a woman who tried to file for ¥4 million in compensation for psychological distress from a nightclub hostess who was engaging in a sexual affair with her husband. 

The Tokyo District court ruled that the woman could not receive compensation because the affair was on practical grounds only, specifically for the hostess to continue 'doing business' with the man.

The 'pillow sales tactic,' or makura eigyo worries some experts, as it may used to justify a wide range of extra-marital affairs, including prostitution.
