Sagan Tosu is a Japanese professional football club based in Tosu, Saga Prefecture. The club plays in the J2 League, the second tier of Japanese football, since 2025 following relegation from the J1 League in 2024.
Sagan is a coined word with various suggested ideas behind where the name came from. One of its is sagan in Japanese. This symbolises many small elements uniting to form one formidable object, for example as a metaphor for a team. Also, Sagan Tosu can be interpreted as Saga-n Tosu in the area's dialect.
In their first season at the J1 League in 2012, confounding the prediction of many critics about their immediate relegation to J2, they maintained their position between 5th and 11th place all the way through the season, except on matchweek 2, in which they were ranked 13th. They were ranked third after the 33rd week, having a chance to qualify for the 2013 AFC Champions League if they hadn't lost to Yokohama F. Marinos in the last match of the season. However, they only lost to Yokohama by 0–1, wrapping up the season in 5th place, while Urawa Red Diamonds defeated Nagoya Grampus and were ranked 3rd. They also became the first club in Asia to sign a partnership with Warrior Sports, Warrior Football – Sagan Tosu who sponsor many overseas clubs, including English side Liverpool FC.
In 2013, they made it to the semi-finals of the Emperor's Cup for the first time in the club's history, becoming the first club based in Kyushu to make it to the semi-finals of the Emperor's Cup since Nippon Steel Yawata had done so in the 1981 edition. In 2013, they invited the A-League team Sydney FC along with the former Italian international player Alessandro Del Piero for a Japan Tour for the first time.
