The boys of The Boss will make their official debut in Japan soon enough, according to their agency Open-World Entertainment. Starting September 18th, the boys will head to Sapporo, Japan to perform at the 2010 Hallyu Music Festival until the 20th, and from thereafter will stay in Japan for 6 months to expand on their international career. According to an official from their agency, "The Boss members will be recording a special Japanese single, and will carry out all kinds of promotional activities throughout the country, although the date of album release is unknown." It looks like Japan will be seeing quite a few K-pop groups in the coming months.
