白色情人節
Giri may be seen in many different aspects of modern Japanese behavior. An example is Japanese gift-giving. It is marked by an unwritten but no less real perceived balance of "giri", whereupon unusually large gifts must be reciprocated. "Giri choco" is a specific term referring to the obligation of close colleagues or associates to provide Valentine's Day or White Day chocolates to each other even if they feel no romantic feelings (although Valentine's Day is a Western tradition that wasn't imported to Japan until relatively recently and White Day is a holiday invented in 1978 by the National Confectionery Industry Association in order to sell twice as many confections each year).
