The Coming of Age Day or Seijin No Hi is celebrated the 2nd Monday of January and is a National Holiday. On this day government officials hold ceremonies where they recognize new adults. The women wear furisode (ふりそで)
and men wear hakama or suits (suits are more common now days).
After a visit to the shrines they go to party with their friends or families. Anyone who turned or turns 20 between April 2, 2014, and April 1, 2015, is invited to participate.
Even Disneyland in Japan celebrates this holiday at their resort. Apparently it is one of the hottest spots to go to celebrate, another being the Toshimaen amusement park. Below is a picture of the show at Disneyland in honor of the holiday.
In some areas of Tohoku, parents of children who died and who would have been 20, attended with photos of their daughters wearing kimonos so they could be present in spirit. Some young adults, whose parents died in the disaster, brought photos of their parents to the ceremony.
According to the Internal Affairs and Communications Ministry, as of January 1st, there were an estimated 1.26 million new adults. This is an increase for the first time in 21 years! This increase included 650,000 men and 610,000 women.
Turning 20 in Japan means that young people have the right to vote, smoke, drink alcohol and marry without permission from their parents.
