Junsu has currently been in Japan holding his "XIA The Best Ballad Spring Tour Concert In Japan" where he has been receiving praise for his live performances and sold out tickets. 

"Since the 13th, Kim Junsu has been performing his high quality '2014 XIA the Best Ballad Spring Tour Concert in Japan' concerts at Tokyo's Yoyogi National Gymnasium with an all live orchestra and band," stated C-JeS Entertainment.

Kim's agency added, "With a 20 person orchestra and 7 person live band, Kim Junsu will perform his musical numbers, ballads and OSTs in front of a sold out crowd of 11,000 fans per day and a total of 33,000 fans." 

The picture that was uploaded was of Junsu practicing with the orchestra as he prepared for his next concert. 

Junsu worked very hard to make sure that the live show went smoothly for his many Japanese fans. 

His voice was matched with a nature theme in order to match the season of spring, which is what the tour is centered on. 

He will be heading off to Osaka next to perform on May 22-24.

The Tokyo show was held for 150 minutes as will the upcoming concert in Oksaka, according to Yahoo Entertainment Singapore. 

Junsu has been singing musical numbers from the shows that he was cast in in Korea including "Mozart," "Elizabeth" and "December," which brought Japanese fans traveling to Korea to get the full Junsu experience.

"Many Japanese fans happily travel all the way to Korea just to watch Kim Junsu's musical, and many people in Japan got to know more about Korean musicals through Kim Junsu," stated a representative from C-JeS Entertainment. 

Junsu also sang songs from drama OSTs that he recorded, many of which his Japanese fans were familiar with. 

The singer included Japanese ballads as well as a few songs from when he was a member of TVXQ.
