New adults attended ceremonies and other festive events Monday to fete Coming-of-Age Day as the government reported that the number of people who turned 20 last year fell by about 30,000 to just 1.24 million, setting a new record low.

According to the Internal Affairs and Communications Ministry, the approximately 630,000 men and 610,000 women who had turned 20 — the legal age for adulthood — as of Jan. 1, reset the record low for a fourth consecutive year.

The new adults were born in 1990, a time when the bubble economy was about to implode and Iraq invaded Kuwait to set the stage for the 1991 Gulf War.
