Actor Yoon Sang Hyun is having a blast in Japan.

The title track of his 4^th Single album '悲しみにさよなら' (Kanasimini Sayonara, or farewell sadness), scored number one on Dowango's K-pop chart and the song 'ふたつのグラス' (two glasses) scored number two.

It is said that the title track is receiving positive reviews comparable to that of a Japanese rock band. And all of the other tracks included in the album, such as the one which he collaborated with the famous pianist Yuki Guramoto, are causing a sensation in Japan.

The tickets to his first Japan tour concert "Black Mountain" sold out rapidly with many eager Japanese fans waiting to get a seat at his performance.

The performance in Osaka and Tokyo are all currently sold out and they even had to create 'standing tickets' for the Tokyo concert due to the overwhelming number of disappointed fans.

Yoon Sang Hyun's agency stated that "He participated in each and every step and is giving his everything to put on the best concert. Fans will be able to see many different sides of Yoon Sang Hyun that they have not known before."

Yoon Sang Hyun's concert "Black Mountain" will kick off in Osaka on the 25^th, and proceed to Nagoya on the 2^nd, and Tokyo on the 10^th.
