The  Coming of Age Day  is a Japanese holiday held in order to congratulate and encourage all those who have become adults  20 years old  in Japan. The annually celebration is held on the second Monday of January at local and prefectural offices  as well as after-parties amongst family and friends. This event started in Japan since at least 714 AD when a young prince dressed new robes and a hairstyle to mark his passage into adulthood  and become holiday in 1948 to be held every year in January 15th. In 2000 the Coming of Age Day was changed to the second Monday of January as a result of Happy Monday System.  Photo by Rodrigo Reyes Marin/AFLO
