Azul Claro Numazu

Azul Claro Numazu was established in 1977 as Numazu Arsenal and slowly progressed through the tiers of Shizuoka prefectural leagues. In 2006 the club began the process of transformation into a professional organisation with the ultimate goal of joining the J.League. The same year the club adopted its current name, Azul Claro (Meaning "light blue" in Portuguese and Spanish).

In 2012 Azul Claro won promotion to Tōkai Adult Soccer League and quickly progressed through its ranks, spending only a season in each of its divisions. Though they have finished only fourth in 2013 Tōkai League, they were considered as serious contenders for admission to the newly created J3 League. On September 17, 2013, the club has been granted the J. League Associate Membership and passed all stages of licensing and inspection by the league. However, they were only the 3rd choice club for the only Regional League spot in J3 so eventually, they had to give way to Iwate Grulla Morioka. The club has won the promotion anyway though—they were selected by the Japan Football League board as one of the teams to play in the 2014 season.

After a 3rd-place finish in the 2016 season, they were invited to play professional football from 2017 and onward, as they'll be the 14th original club in the J3 League.

On 24 October 2023, Azul Claro Numazu announced that the club was officially granted a J2 license after a decision by the J.League's Club Licensing Board.

On 14 December 2025, Azul Claro Numazu were relegated to the Japan Football League after a 1–1 draw with Reilac Shiga FC in the second leg, losing 4–3 on aggregate. This brought an end to their eight-year stay in the third tier and marked their return to the fourth tier.
