Honmei Choco (本命チョコ), literally, "true feeling chocolate" in Japanese. Honmei choco is chocolate given by women on Valentine's day to men whom the giver has romantic feelings for. This is often given to boyfriends, prospective boyfriends, and husbands. Honmei chocolate is higher-quality and more expensive than giri choco ("obligation chocolate"). Giri choco is given to male coworkers and other men to whom the woman has no romantic attachment.[1]
Homemade honmei choco is also popular.[2]
This is generally reciprocated on White day, celebrated on March 14th, when men buy candy and gifts for women.
