Rising Hallyu star Song Joong Ki recently faced an embarrassing moment during his stay in Tokyo's Shinjuku district. The embarrassing incident began when the actor took a trip up to Tokyo for the program, 'QTV Special I'm Real Song Joong Ki.' For his first night's stay, the actor lost a game while playing with his affiliated company members and thus had to face the punishment of visiting a nearby convenience store in his pajamas. Reluctantly, the star fulfilled the task, but decided to don sunglasses to hide his identity. Despite his efforts, however, he was immediately discovered in the hotel elevator by some fangirls. These fangirls joked, "You are not as popular in Japan as you are in Korea, so don't worry" and "Truthfully I am Jung Yonghwa's fan." Source: Newsen
