Is a Japanese rite of passage held on the second Monday of January. It is held in order to congratulate and encourage all those who have reached the age of majority over the past year, and to help them realize that they have become adults. This Ceremony held at local and prefectural offices, as well as after-parties amongst family and friends. This ceremony have been celebrated in Japan since at least 714 AD, when a young prince donned new robes and a hairstyle to mark his passage into adulthood The holiday was first established in 1948, to be held every year on January 15. In 2000, as a result of the Happy Monday System, Coming of Age Day was changed to the second Monday in January
Seijin-shiki marks of one's coming of age (age of majority), which reflects both the expanded rights but also increased responsibilities expected of new adults. The ceremonies are generally held in the morning at local city offices throughout Japan. All young adults who turned or will turn 20 between April 2 of the previous year and April 1 of the current one and who maintain residency in the area are invited to attend. Government officials give speeches, and small presents are handed out to the newly recognized adults.
Many women celebrate this day by wearing furisode, a style of kimono with long sleeves that hang down, and zōri sandals. Since most are unable to put on a kimono by themselves due to the intricacies involved, many choose to visit a beauty salon to dress and to set their hair. A full set of formal clothing is expensive, so it is usually borrowed from a relative or rented rather than bought especially for the occasion. Men sometimes also wear traditional dress (e.g. dark kimono with hakama), but nowadays many men wear formal Western clothes such as a suit and tie more often than the traditional hakama. After the ceremony, the young adults often celebrate in groups by going to parties or going out
