About 1.22 million people born in 1991 who had reached the age of 20 before January celebrated the Coming of Age holiday on Monday. Their ranks totaled 20,000 less than in 2010.
The figure reset the record low for people achieving formal adulthood for the fifth year in a row, according to statistics compiled by the internal affairs ministry.
The ministry started logging the statistic in 1968. It peaked in 1970 at about 2.46 million, when the baby boomer generation started hitting 20.
This year, about 620,000 men and 600,000 women celebrated the national holiday. The ratio of new adults to the population as a whole was 0.96 percent, marking eight consecutive years of decline.
Meanwhile, more than 1,200 young people took part in the Coming of Age ceremony at Tokyo Disneyland in Urayasu, Chiba Prefecture, the same day.
At the 11th ceremony, attendants wearing colorful “hakama” (traditional kilt) and kimono mingled with Disney mascots Mickey and Minnie Mouse.
Urayasu was damaged by soil liquefaction during the monster earthquake last March 11.
“Although the water supply at my home was shut off for a month and a half due to liquefaction, I could attend the coming-of-age ceremony,” Shunsuke Kuroki, a college sophomore, said. “I hope I can contribute to the reconstruction as an adult from now on.”
