Ulsan, the leader of the K-League, could hardly open the goal of Kawasaki, the leader of the Japanese J-League.
Oh Se-hoon's header shot was blocked by Kawasaki keeper Jeong Seong-ryong's super save, and Lee Dong-jun's long-range shot was also in the keeper's arms.
After 90 minutes without scoring, Ulsan went into extra time with goalkeeper Jo Hyun-woo's dazzling save, and Ulsan overcame the risk of conceding.
The penalty shootout was also tight.
Ulsan was in crisis after Won Doo-jae's loss, and Lee Dong-jun's kick was blocked by Jeong Seong-ryong, but Kawasaki's two misses took a breather.
And at the last moment, Jo Hyun-woo flew up dazzlingly.
Jo Hyun-woo accurately predicted the direction and flew his body to hit the opponent's 5th kicker and cheered.
Ulsan's last kicker, Yoon Bitgaram, shook the net and ended the long game.
