History
Founded in 1965, they played in the Ibaraki Prefecture University League until 1998. They were promoted to the Kanto University League Division 2 in 1999 but relegated after one season. They were promoted again in 2002.
In November 2004, with the recommendation from the Japan University Football Association, the club participated in the Regional League promotion series. They finished runners-up and were accepted by the Japan Football League. The club became the third university club that were allowed to play in the JFL following Kokushikan University SC and Shizuoka Sangyo University SC (the former withdrew and the latter was relegated).
As of 2010, the JFA has barred all university clubs from competing in the Regional Promotion Series, which means that no further university clubs can compete in the JFL. RKU, however, was still allowed to compete in the JFL until their relegation in the same season.
