In 1991, the "F.C. INAX Soccer Club" was founded at the Saga Plant of Kyushu INAX (now Saga LIXIL Works), a subsidiary of INAX. Starting in the 5th division of the Saga Prefectural League, they climbed to the 1st division within five years. In 1997, the club changed its name to "Kyushu INAX Soccer Club."
In 1999, the club debuted in the 79th Emperor's Cup, where they faced Josai University and lost their opening match. By 2025, they had participated in the Emperor's Cup a total of 12 times.
In 2000, they claimed their first championship just five years after being promoted to the first division of the prefectural league. They also secured second place in the Kyushu Prefectural League Finals and earned promotion to the Kyushu League for the first time without needing a play-off match, thanks to NTT Kumamoto FC's promotion to the JFL.
They played in the Kyushu League for three seasons from 2001 to 2003, finishing 7th, 9th, and 11th, which led to their relegation to the Saga Prefectural League. In 2004, their first year after relegation, they won the title but were defeated by FC Ryukyu in the second round of the prefectural league finals. In 2005, they claimed back-to-back titles but lost in the first round of the finals to the Kumamoto Prefectural Teachers' Kicking Brigade, remaining in the Saga Prefectural League. In 2006, they missed out on a third straight title, losing to Kawazoe Club.
At this time, they achieved their first-ever victory in the Emperor's Cup by defeating Kashiwa Reysol U-18 in the opening round of the 85th Emperor's Cup in 2005.
In 2007, they clinched the prefectural league championship for the first time in two years and triumphed in the Kyushu prefectural league finals, making their return to the Kyushu League after five seasons.
In 2009, they secured victory in the Kyushu qualifiers and made their debut in the All-Japan Adult Football Championship. They triumphed in the first round against Sagawa Express Chugoku (ja) and in the second round against FC Korea, advancing to the quarterfinals, where they were defeated by AC Nagano Parceiro.
On July 1, 2011, the team's name was officially changed to "Saga LIXIL FC" following a rebranding in April of that year.
In 2015, they faced Oita Trinita in the first round of the 95th Emperor's Cup, their seventh appearance in the tournament. It was their first match against a J. League club, where they lost 0-2. They ended up finishing ninth in the Kyushu League and were relegated to the Saga Prefectural League for the first time in nine years after losing a play-off match to the Kumamoto Prefectural Teachers' Kicking Brigade. However, in 2016, they won the prefectural league and finished as runners-up in the final tournament of all Kyushu prefectural leagues. With Kagoshima United FC Second ceasing activities, the team returned to the Kyushu League within a year without requiring a play-off match.
In the 2019 Kyushu League, the team achieved a record third-place finish. However, in the summer of 2021, due to the impact of the new coronavirus and a decline in business performance, the company decided to stop supporting the team. In response, the team transitioned into a club team in 2022 with backing from around 50 local companies. A management corporation called "General Sports Union Brew Kashima" was established, and the team's name was changed to "Brew KASHIMA" (Brew Kashima). The name "Brew" reflects the region's sake brewing tradition and is derived from the nickname "Menbrews" used during the LIXIL era. It also symbolises traditional performing arts like Menbutsu and hook flotation. The emblem and mascot remain almost identical to those of Saga LIXIL FC.
On January 7, 2025, the team was renamed "Brew SAGA" (Brew Saga), and the operating corporation became "Football Club Saga Co., Ltd." to expand its activity area across the entire Saga Prefecture. The emblem was also updated while retaining the motif of the floating face. Former FC Gifu staff and management consultant Miyagi "Ryo" was appointed as the representative director, while former Fukuoka SoftBank Hawks Keinosuke Ichikawa and Hitoshi Isozaki joined as new directors. On January 16, an advisory contract was signed with Takahiro Masukawa. Following an open recruitment process, Hayato Chichiiwa, an active university student, was appointed as a new director.
