Sanfrecce Hiroshima

The club was a former company team of Toyo Kogyo Soccer Club (東洋工業サッカー部) in 1938 and played in the semi-professional Japan Soccer League.

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 Mazda SC (マツダSC) in 1981.

During the 1969 season, they participated in the Asian Club Cup, forerunner to today's AFC Champions League; at the time, the tournament was done in a single locale (in that year it was Bangkok, Thailand), and they ended up in third place, the first participation of a Japanese club in the continental tournament. This also cost them the league title to Mitsubishi/Urawa, and although they won another title in 1970, since then the club has been out of the running for the title, with exceptional seasons such as 1994 when they won runner-up.

The Toyo Industries that became the first JSL champions also completed the first double by taking the Emperor's Cup. They were also the first of three "Invincibles", undefeated champion clubs in Japan (the others were Mitsubishi in 1969 and Yamaha in 1987–88), although only Toyo completed a double.

Ogi Matsumoto and Yasuyuki Kuwahara went on to win the 1968 Olympic bronze medal for the Japan national team.

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").

In 2002, Sanfrecce became the first former stage winner (first stage, 1994) to be relegated to the lower division, J2 League. But it only spent a year there, finishing second the very next season to regain promotion back to J1. The club finished 16th in the 2007 season and were relegated to J2 League after they were beaten by Kyoto Sanga in the promotion/relegation play-off. In the following season in 2008, Sanfrecce nevertheless won the J2 League title at the first attempt, having 84 points (a difference of 25 points with the runner-up clubs) with six matches left.

By virtue of earning fourth place in the 2009 season and Gamba Osaka retaining the Emperor's Cup, Sanfrecce qualified for the 2010 AFC Champions League where they were knocked out in the group stage.

With their second consecutive title win, Sanfrecce became the second club to successfully defend their crown since Kashima Antlers in 2009. Sanfreecce then qualified to the 2014 AFC Champions League.

Sanfrecce started off the 2014 season on 22 February 2014 during the Japanese Super Cup against 2013 Emperor's Cup winners Yokohama F. Marinos where Gakuto Notsuda and Takuma Asano went on to score the goal to secure a 2–0 win. In the 2014 AFC Champions League, Sanfrecce finished as runners-up in the group stage thus seeing the club advance to the round of 16 for the first time in the club history.
