The club was an original founder ("Original Eight") of the now-disbanded Japan Soccer League (JSL) in 1965. They dominated the JSL's early years, winning the title 4 times in a row – a feat that was later equaled by Yomiuri SC/Verdy Kawasaki. The name change was made at in 1981. When JSL disbanded and became the J.League in 1992, it dropped the company name and became "Sanfrecce Hiroshima". Alongside JEF United Ichihara Chiba and Urawa Red Diamonds they co-founded both leagues ("Original Ten").
