Ryutsu Keizai Dragons Ryugasaki

Founded in 2001 as Ryugasaki FC, the team started competing in the lower divisions of the Ibaraki Prefecture Leagues. Although established as an independent NPO, the club was mainly made up of student players from Ryutsu Keizai University and acted as a farm team for Ryutsu Keizai University, which at the time played in the Kanto University League and joined the JFL in 2005.

In 2003, the club renamed itself Club Dragons (クラブ・ドラゴンズ). In 2005, they earned promotion to the Kantō Soccer League Division 2, won the championship right away, and have been competing in Kantō League D1 since 2006. They were relegated twice, in 2010 and 2013, but both times spent only one season in Division 2 before bouncing back.

In 2014, the Dragons made it to the final of the Shakaijin Cup, earning a spot in the Regional League promotion series , even though they had played the season in the second division of the Kantō League. They secured third place in the promotion tournament and were officially promoted to the 2015 Japan Football League.^[1] With their promotion, the club decided to rename themselves Ryutsu Keizai Dragons Ryugasaki starting in 2015.

In 2019, RKU Dragons Ryugasaki were relegated to the Japanese Regional Leagues starting in 2020, following a five-year run in the JFL.

In 2023, after finishing in 10th place in Kanto Division 1, they were relegated to Kanto Division 2. They spent only the 2024 season in Division 2, earning promotion back to Division 1 as champions. However, after finishing in ninth place in the 2025 season, they were relegated once again to Division 2.
