Music group TVXQ will perform songs from its second single released in Japan for the opening part of the Nation 2005 concert to be held Aug. 27 in Kobe.

The group`s single, entitled `Somebody To Love,` took the seventh spot on the Japanese Oricon chart on the day of its release, attesting to the group`s rising popularity in Japan.

The `Nation` concert, which was previously called `A-Nation,` is the only pop-concert in Japan, where the majority of large concerts are typically staged by rock musicians. Held in the form of a nationwide tour, the `Nation` concert has grown into the largest pop-concert in Japan since top artists from various talent management agencies began participating in 2004.

Singer BoA, who has participated in the concert for four straight years, will perform at Nation 2005 in Tokyo on Aug. 20 and in Kobe on Aug. 27.
