Kim Hyun-joong's second single album "Heat" in Japan has been enjoying enormous popularity.
Since its release in July, the album has sold 200,580 copies, according to the Oricon Chart. This makes Kim the first K-pop singer to post sales in excess of 200,000 copies for a single album in Japan this year.
Over 138,000 copies of the album were sold on July 4, the first day of its release, which immediately catapulted it to the top of Oricon's daily chart.
Since then, the album has swept various music charts including Oricon's weekly and monthly charts.
Kim's achievement exceeds that of Super Junior's "Opera," which has sold 184,000 copies since it was released in May, and TVXQ's "Android," of which 175,000 copies have been sold since July.
