The annual event called Seijin no Hi (Coming of Age Day) is held in Japan on the second Monday of every January to congratulate and encourage all those who have turned 20 — the country's official age of majority.
Official ceremonies are held in the morning at local city offices throughout Japan, with government officials giving speeches and small presents being handed out to the participants. After that, the newly-recognized young adults hold after-parties among family and friends.

It is believed that this rite has been held since at least 714 AD, when a young prince donned new robes and a hairstyle to mark his own entry into adulthood. The national holiday was officially established in 1948. Photo: Participants clad in Japanese kimono walk together following the Coming of Age ceremony in Tokyo, on January 8, 2018.
