Popular K-pop boy band JYJ will open a massive annual festival in Seoul late this month for its local and Japanese fan clubs, the group’s management agency said Wednesday.

The trio has held the “JYJ Membership Week” expo annually in the capital city for free since 2012 to better communicate with their fans, drawing more than 20,000 people each year from home and abroad.

This year’s event, the third of its kind, is scheduled for July 31-Aug. 3 at the COEX convention center in southern Seoul, according to C-Jes Entertainment.

During the expo themed “All about JYJ music,” visitors can see videos and photos as well as some 600 stage costumes of the group and a set from the filming of the video of the group’s latest album, the company said.

About 20,000 randomly chosen fan club members, including 3,000 from Japan, are expected to attend the free event, the agency said. (Yonhap)
