Fluent in both Korean and Japanese, Yunho has achieved commercial success throughout Asia as a member of TVXQ. Known as "Asia's Stars" and the "Kings of K-Pop", TVXQ have released fifteen studio albums and performed on record-breaking concert tours; their sixth Japan-wide tour, the Time Tour, was the highest-grossing concert tour ever held by a foreign music act in Japan. TVXQ are the first non-Japanese music act to hold a concert in the Nissan Stadium, Japan's largest outdoor stadium. According to the Oricon, TVXQ records the most number-one singles for a foreign music act in Japan. They have since sold over 7 million albums there, making them one of Japan's best-selling foreign artists.
