Sagan Tosu is a professional football club based in Tosu, Saga Prefecture, on the island of Kyushu, Japan, currently competing in the J2 League. The club's official name is Sagan Tosu, and they play at the Ekimae Real Estate Stadium. Founded in 1997, the club's colors are orange and blue, owned by a consortium led by the internet company CyberAgent. The name 'Sagan' is derived from 'Saga' and a term for 'legend,' aiming to create a new legend for the region. The club spent many years in the lower divisions before a historic promotion to J1 in 2012, where they remained for a decade, a period that defines their key era. During that time, they were known for a highly organized, defensively robust style of play that made them a difficult opponent for any team. After relegation to J2, the modern era sees Sagan Tosu as one of the division's strongest sides, consistently challenging for promotion back to the top flight with a blend of experienced campaigners and promising youth. Their supporters, though fewer in number than metropolitan clubs, are famously passionate and create a loud, concentrated atmosphere in their compact stadium. Sagan Tosu is a well-run club with a clear identity, determined to return to J1 and continue building its legacy.
