Nankatsu SC

The club's origin dates back to 1983. In those days, the club mainly centered its attention on Tokiwa Junior High School alumni who wanted to play for the club, inserting a certain influence on the club, which ended up naming themselves Tokiwa Club. The club joined the Tokyo Adult Soccer League, and was promoted to its 2nd Division in 1994. The club repeatedly switched between the second and third division, as the club couldn't gain consistency in a higher-level league. In 2011, the Katsushika Ward Football Federation established the NPO International Football Promotion Association, which is an organization under the Federation for clubs aiming to join the J.League. Tokiwa Club, as it was called at the time, became an affiliate.

The club was renamed in 2012, becoming Katsushika Vitoard (葛飾ヴィトアード). In 2013, the club welcomed Yōichi Takahashi as the new president, renaming the club as Nankatsu SC, in allusion to his (Yōichi Takahashi's) globally famous manga and anime Captain Tsubasa, which attracted the attention of many young people in Japan, and culminated in an increasing rise of interest about football in the nation. They established an U-12 team for elementary school students in 2013, and an U-15 team for junior high school students in 2015. From 2015 to 2017, they signed partnerships with Nankatsu SC Fukuoka, SC Sagamihara, and CE Sabadell FC.

In January 2019, Nankatsu SC Co. Ltd was established to operate the first-team, transferring the team's management. The following year, they were approved as a member of the J.League 100 Year Plan, alongside Vonds Ichihara, FC Osaka, Veertien Mie and Iwaki FC.

On 14 July 2021, Valuence Holdings acquired 33,5% of the Nankatsu SC Co. Ltd. shares (the other 66.5% remained in the ownership of Yōichi Takahashi). In addition, Shinsuke Sakimoto, then Valuence Holdings CEO, became Nankatsu SC Co. Ltd. president. The same year (2021), Nankatsu SC, who were then a newly promoted team from the Tokyo Metropolitan League, making at the time its regional debut, were promoted from the Kanto Soccer League 2nd division, finishing as 2021 runners-up.

In the 2022 season, they played in the Kanto Soccer League 1st division, successfully avoiding relegation, despite being threatened by it several times during the league season. Nankatsu made their debut at the Shakaijin Cup on 2022. Their first match on the competition was a win against FC Tokushima by 1–0, with their lone goal scored by center-back Deivisson. Their second match was the debut's opposite, as this time they lost the match by 1–0 against Veroskronos Tsuno, forcing them to early exit the tournament at the Round of 16.

In the 2023 season, they continued to play in the KSL's 1st division, and ended up mid-table. Nankatsu SC was not able to make any other national appearances during the year, as they failed to qualify for the Emperor's Cup, Shakaijin Cup and the Regional Champions League.

In 2024, they are playing their third consecutive season in Kanto's top division, a feat shared between them and their women's team. To qualify for the Emperor's Cup, clubs in Tokyo have to win the Tokyo Soccer Championship. To qualify for the tournament, non-university teams from regional and prefectural leagues needs at least to be a finalist in Tokyo Senior Championship. Fortunately for Nankatsu, they managed to win the title following a 5–2 triumph over Aries Tokyo FC. This win qualified them to the aforementioned Tokyo Soccer Championship. Starting on the first round in the six-team tournament, they were paired with JFL club Yokogawa Musashino FC. If they won the match, they would be playing against Waseda University's football club, who were seeded in the semi-final. Emperor's Cup aspiration came soon to a halt for Nankatsu SC, as they lost by 2–0 their match against Yokogawa Musashino FC. From July onwards, they played in the Shakaijin Cup qualifiers, in hopes of appearing in the national-level scene once again.
