Sanfrecce Hiroshima

As Mazda team

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. 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").

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.

1960s

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.

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

2000s

In 2002, Sanfrecce became the first former stage winner (first stage, 1994) to be relegated to the lower division, J2. 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 J.League Division 2 after they were beaten by Kyoto Sanga in the promotion/relegation play-off. In 2008 they nevertheless won the J2 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 Asian Champions League, where they were knocked out in the group phase.

On 24 November 2012, Sanfrecce defeated Cerezo Osaka 4–1 to seal their first ever J.League Division 1 title.

On 7 December 2013, Sanfrecce defeated Kashima Antlers 2–0, securing their second J.League Division 1 title following a thrilling finish to the season which saw first-place Yokohama F. Marinos losing their final league game, handing Sanfrecce the title. With their second consecutive title win, Sanfrecce became the second club to successfully defend their crown since Kashima Antlers in 2009.

2015 proved to be a great year for Sanfrecce, finishing 1st in the 2nd half of the season, then finishing 1st overall, just 2 points above Urawa Red Diamonds, to qualify and represent Japan in that year's FIFA Club World Cup. They would finish 3rd, after winning, 2–1, against Chinese side Guanzhou Evergrande in the 3rd place match.

In 2018, after Sanfrecce progressively trailing towards a J1 title, as it led the standings after Round 5, the club fell down to 2nd-place at the end of the season. The club saw Kawasaki Frontale win the league as Sanfrecce lost four of their last five league matches.

In 2022, the club was relieved to experience another good season, under the management of newly appointed German coach Michael Skibbe. Underrated by many because of the previous season, the club fought for the title at every competition it played until the very end. The Violas finished 3rd place at the J1 League, as runners-up to J2 club Ventforet Kofu in the Emperor's Cup final, and as J.League Cup champions. The J.League Cup was won in dramatic fashion against Cerezo Osaka, as the club managed to comeback from a 1–0 loss with two goals scored by mid-season Cypriot signing Pieros Sotiriou. Both goals came very late in the match, being scored at the 96th and 101st minute of the match, during the added time of the second half. For his efforts to make the team competitive at every competition Sanfrecce partook in, Skibbe won J.League Manager of the Year, the club's 4th Manager of the Year title.
