White Day is an anniversary created in Japan in 1980. This culture not only spread in Japan but also was exported to South Korea and Taiwan. It is celebrated on March 14, one month after Valentine's Day. On Valentine's Day, women give gifts to men; on White Day, men who received chocolate on Valentine's Day return the favor and give gifts to women. This holiday is starting to gain popularity in Hong Kong, where Japanese influence is strong. The observance of Valentine's Day in Japan, particularly among students, is somewhat different than in the West. Valentine's day is mainly for the girls to present chocolates (either store-bought or handmade) to the boy of their choice. The concept of "Giri-Choco" (Japanese: 義理チョコ), which translates as "Obligatory Chocolate", has also developed, where a girl will give chocolate to those close to her (co-workers, for example) but in whom she has no romantic interest. When White Day rolls around, it is the boy's turn to return the gift in what is called "sanbai-gaeshi" (3倍返し) or "triple return", since the gift the boy gives is supposed to be three times the value of the gift received initially
