浦安SC

Founded in 1989 as Urayasu Junior Football Club, the team was established in Chiba Prefecture. The name refers to a mix composed by Brionac, a spear appeared in Celtic mythology, and Becca, a one-seater ship used to collect nori, a Japanese cuisine delicacy, typical of that region. The mascot – Maiko Becca – was presented in 2017, one year after drawing its design. A JFL membership was granted in 2016, the season where Briobecca gained promotion to the 4th tier. After two seasons on the league, the club got demoted back to the Kantō Soccer League. On 2022, the club participated in the 2022 Shakaijin Cup, winning the tournament. Their performance at the competition qualified the club to the 2022 Japanese Regional Football Champions League. Remaining unbeaten throughout the tournament, Briobecca Urayasu was able to win the title. Then, the club officially returned to the Japan Football League after a five-season absence from it. The club secured promotion, and the title, only at the final round, after a vital win over Tochigi City FC by 3–1, which also secured their first title in the competition. On the same year, the club recorded their worst performance at the Kanto League since their JFL relegation on 2017.
