Renofa Yamaguchi

The original football team consisted of a group of teaching staff who were based within Yamaguchi prefecture, a team called Yamaguchi Prefecture Teachers Football Club (山口県サッカー教員団, Yamaguchi-ken sakkā kyōin dan), often abbreviated to Yamaguchi Teachers or Yamaguchi KFC (compare Tochigi S.C. and Gainare Tottori, who started as teachers' clubs and are now members of the J.League).

In February 2006, the Yamaguchi Football Association eyed the placement of a team from Yamaguchi in the J.League. Setting its heart of operations at Yamaguchi Teachers, a new football club was established. At the same time, a public appeal was made to name the new club, with Renofa Yamaguchi F.C. being decided in March of the same year. The word renofa is a wasei-eigo, a combination of three English words: renovation, fight, and fine.

Without a specified home ground, the team played Chūgoku league matches across a number of different venues within the prefecture, including Yamaguchi Ishin Park Stadium, Yamaguchi Kirara Expo Memorial Park, Onoda Football Park, Shunan City Athletic Stadium, and Yamaguchi Football Park. Now however, home games are played at Yamaguchi Ishin Park Stadium.

Though structured with a hometown manager and local players, sponsored by local business and enterprises, and local action plans within the local community, Renofa Yamaguchi F.C. is aiming for a national future in the J.League.

In the days of Yamaguchi Teachers, the team frequently finished mid to low table in the Chūgoku league. However, since the establishing of the new club in 2006, the team has consistently improved their final league position. This culminated in the 2008 season where they achieved their first league win. In the All Japan Regional Football Promotion League Series of that year the team finished fourth in the final round, missing the opportunity for promotion to the Japan Football League. The 2009 season saw them win their first Emperor's Cup match, beating Mitsubishi Motors Mizushima F.C. in a penalty shoot out.

Since the team's formation it had operated as a private organisation, however when the Nonprofit organization Yamaguchi Athletics Club was established on 24 May 2011, managing control of the team changed hands putting the new NPO in charge.

After finishing in 4th place in the 2014 Japan Football League and securing the necessary licensing, the J.League officially welcomed Renofa Yamaguchi to join the J3 League, starting from the 2015 season. Their J.League debut came in 2015 season. On 23 November 2015, Renofa earned their first and successful promotion from the JFL after winning the J3 League. The club was promoted for the J2 League ahead of the 2016 season. The club was guaranteed promotion after a 2–2 draw against Gainare Tottori in the closing rounds of the season, as Renofa were working towards J2 licensing before the season ended, for the promotion to be actually earned.

On September 26, 2023, Renofa Yamaguchi announced that they had officially been granted a J1 License.

In 2025, Renofa Yamaguchi were relegated to the J3 League for the next season after finishing 19th, marking their worst performance in the league and ending a nine-year run in the second tier.
