Coming of Age Day (成人の日 Seijin no Hi) is a Japanese holiday held annually on the second Monday of January. It is held in order to congratulate and encourage all those who have reached the age of majority (20 years old (二十歳 hatachi)) over the past year, and to help them realize that they have become adults. Japan lowered the age of adulthood in 2018 from 20 years of age to 18 which is set to take effect in 2022. This change has caused confusion on the status of the holiday, and raised concerns among the kimono industry which profits from the garments worn during the ceremonies. Festivities include coming of age ceremonies (成人式 seijin-shiki) held at local and prefectural offices, as well as after-parties among family and friends.
