LE SSERAFIM is gearing up to light up Japan's year-end festival stage.

The group will perform at COUNTDOWN JAPAN 25/26, taking place from December 27 to 31 at Makuhari Messe in Chiba, Japan.

First launched in 2003, COUNTDOWN JAPAN is one of Japan's largest and most iconic music festivals, featuring top artists every year and drawing massive crowds with unforgettable performances.

LE SSERAFIM is scheduled to perform on the second day of the event, joining a star-studded lineup that includes singer-songwriter Vaundy and hip-hop duo Creepy Nuts.

Their popularity in Japan continues to soar. Earlier this year, the group surpassed 100,000 album shipments for the fourth consecutive time with their fifth mini-album HOT.

They were also the only K-pop group invited to ZOZOFES, the festival hosted by Japan's largest fashion platform ZOZOTOWN, and they are set to make their long-awaited Tokyo Dome debut next month.

Meanwhile, LE SSERAFIM will release their first Japanese single SPAGHETTI on October 24 at 1 p.m.
