Under the theme of "Everything About JYJ Music," the program of the four-day event includes a fan expo, a meeting with fans and a showcase.
Admission to the two events - fan expo and showcase - is free to members of the band’s fan club, according to the group’s management agency in Seoul, C-Jes Entertainment.
However, tickets for the fan meeting are available only to randomly selected fans, the agency said.
Yoo-chun, a member of JYJ, thanked fans for coming to the annual festival. “We’ve been able to hold the big event as a large number of fans have come to it,” he said.
"We want to give our fans as many presents as possible," he said.
