Epik High ventures into Japan?

Epik High will be going to Japan near the end of August to perform with E.T. Tei. They will be performing at the Yokohama BLITZ! on the 23rd and 24th of August. In the mean while, Epik High is scheduled to be in Thailand from August 9th - 12th. They will have a press concert and fan meet at the Siam Discovery Center on August 10th. Epik High will also be on various TV shows to promote themselves in Thailand. (Super Junior will also fly with Epik High to Thailand, but will go there seperate ways once in Thailand to film a commercial). It seems Epik High is slowly expanding and concentrating on other asian markets. Is this the start of another Korean group trying to venture into the Japan market? It's too early to tell, but Epik High makes great music and they can be successful anywhere.
