Kagoshima United

Origins (1959–2013)

Volca Kagoshima was established in 1959 as Kagoshima Teachers' Soccer Club. The club was a founding member of the Kyushu Soccer League in 1973. Since the league's inception, the club had always played in this league and never be relegated to the Prefectural Leagues until the merge with FC Kagoshima in 2014. They advanced to the Regional League promotion series five times, but never succeeded to promote to the upper tier, Japan Football League, known as the highest level for amateur club football in the country. The club changed the name from Kagoshima Teachers to Volca Kagoshima in 1995.

FC Kagoshima was established in 1994 as an affiliated club of the National Institute of Fitness and Sports in Kanoya. They were promoted to the Kyushu Soccer League as early as 2004 and changed the name to Osumi NIFS United FC.

Both of Volca and NIFS have been seeking the way to promote to the JFL separately. The idea of a merged club of Volca and FC Kagoshima (renamed from NIFS in 2010) had been discussed by the Kagoshima Prefectural Football Association as early as 2012, however, it was failed to reach an agreement at that time. Although Volca and FC Kagoshima had applied for J.League Associate Membership separately, both sides restarted their talk about the merger, then finally agreed with merging their clubs to aim promotion to the J.League, in response of the advisory by the J.League organization. As both clubs had advanced to the final round of the Regional League promotion series in 2013, the merged club earned the promotion to the JFL of 2014.

Kagoshima United (2014–)

The two clubs, Volca Kagoshima and FC Kagoshima, were merged in 2014 to form Kagoshima United. In November 2015, after finishing promotion zone in 2015, they received J.League license to participate in the J3 League.

In 2018, Kagoshima United was promoted to the J2 League for the first time in history from 2019 after five years at the J3.

In 2019, Kagoshima United was instantly relegated back to the J3, after a 21st place finish in their J3 debut season.
