Coming of Age Day (成人の日, Seijin no Hi) is a Japanese holiday held in order to encourage and congratulate those who have reached or will reach the age of majority between April 2 of the previous year and April 1 of the current year. The holiday is usually held on the second Monday of January on each year, so this year, that day is January 13.


During this holiday festivities - such as ceremonies held at the local and prefectural offices and parties among family and friends - are organized.

In Japan coming of age ceremonies have been celebrated since at least 714 CE when a young prince marked his passage into adulthood by putting on new robes and getting a new hairstyle, but the holiday was first established in 1948 and was held every year on January 15. In 2000 Coming of Age Day was changed to the second Monday of January as a result of Happy Monday System*.

Usually women wear furisode (a kimono with long sleeves that hang down) and zori sandals. Due to the intricacies, many visit a beauty salon to dress and set their hair, but the kimonos are often borrowed or rented since a full set is rather expensive. Men, on the other hand, usually wear Western clothing such as suits and ties instead of the traditional kimono and hakama.

However, the original purpose of the celebration seems to disappear with younger generations. Nowadays young adults see the celebration more like a reunion instead of an encouragement.

*Happy Monday System (ハッピーマンデー制度, Happī Mandē Seido) refers to modifications of the Japanese law to move a number of holidays on Mondays thus creating three days weekends for those working five days weeks.
