As discovered earlier, the artists of JYP Nation announced that they'd be coming together for a mega "JYP Nation in Japan 2011" concert in Japan.  Further information was released to allkpop today, including the line-up of J.Y. Park, Lim Jung Hee, the Wonder Girls, JOO, 2AM, 2PM, miss A, and San E. The concert will especially be a treat for fans since 2AM wasn't able to attend the first concert last year due to their own concert. Details were first dropped through 2PM's Tokyo concert and high touch event, exciting fans everywhere. The two-day concert will be held at the Saitama Super Arena on August 17th and 18th. Representatives of JYP Entertainment stated, "JYP Nation garnered a 10,000 member audience last year. This summer, we'll be holding a large-scale version in Japan to continue its success. With the anticipation rising, we promise to work hard to guarantee a fun concert." Tickets can be reserved through the Hottest Japan mobile site starting June 1st.
