Yokohama FC

Yokohama was formed on 25 December 1998 following the merger of Yokohama's two J.League clubs, the Flügels and the Marinos. Flügels supporters felt that their club had essentially been dissolved rather than merged with, so rejected the suggestion that they should start supporting Marinos – who had been their crosstown rivals. Instead, with money raised through donations from the general public and an affiliation with talent management company IMG, the former Flügels supporters founded the Yokohama Fulie Sports Club. Following the socio model used by FC Barcelona, the Fulie Sports Club created Yokohama Football Club, the first professional sports team in Japan owned and operated by its supporters.

For its first season in 1999, Yokohama hired former Germany national team and FIFA World Cup star Pierre Littbarski to be the manager and Yasuhiko Okudera, the first Japanese footballer to play professionally in Europe, to be the chairman. The club attempted to gain entry directly into the professional J.League, but the Japan Football Association only permitted entry to the amateur Japan Football League (JFL), at the time the third level of the Japanese football league system, and ruled that the club would not be eligible for promotion into J.League Division 2 at the end of its first season. So, despite finishing as JFL champion in 1999, Yokohama finished as JFL champion again in 2000 before being promoted to J.League Division 2.

Although they had a dire season in 2005, ending 11th out of 12, they were in the top half of table throughout the 2006 season. Yokohama had lost all of their pre-season matches, including against college teams; they later hired player-manager Takuya Takagi, under whom they saw success. On 26 November 2006, they finished in the top spot of the J2 League and were promoted to the J. League 1. Yokohama's financial situation remained poor, with no ownership of their stadium or training ground, and few staff members. One of their players, Kazuyoshi Miura, last played for the team at the age of 53, and a former player, Atsuhiro Miura (one of their main players before his 2010 retirement) was 36 when he last played for the club. These players once played for the Japan national team.

In 2007, just the ninth year of its existence, Yokohama played its first season in the top flight of Japanese football. After a poor season, the team were relegated with five games of the season still remaining. Despite their early relegation, Yokohama defeated title contenders Urawa Red Diamonds on the last day of the season, allowing Kashima Antlers to secure the J.League Division 1 title.

In 2018, Yokohama narrowly missed out on automatic promotion by goal difference. The team made it to the J2 promotion final, losing to Tokyo Verdy on an stoppage time winner. In 2019, Yokohama finished second in J2 and gained automatic promotion to J1.

After finishing in last place in 2021, Yokohama would be relegated back to J2 for the 2022 season, but they bounced back immediately to J1 League the next year. On 25 November 2023, Yokohama FC were relegated from J1 to J2 from 2024 after the club lost to Shonan Bellmare. On 11 November 2024, Yokohama FC secure promotion again to J1 from 2025 after draw against Renofa Yamaguchi 0-0 in final matchweek and ended one year stint in second tier.
