Hallyu star Kim Hyun-joong’s second single album “Heat” released in Japan on Wednesday sold 137-thousand copies on its first day, topping the Oricon daily music chart in the single album category.

The album features two songs, including the title track “Heat” written by popular Japanese group B’z, and “Let’s Party.”

Sales of Heat doubled release sales of Kim's previous album “Kiss Kiss/Lucky Guy,” which set the previous sales record as a foreign debut song when it came out January 25th.
