Kashiwa Reysol

Hitachi SC (1939–1992)

The club started in 1939 and was officially formed as the company team, Hitachi, Ltd. Soccer Club in 1940 in Kodaira, Tokyo. The club formed the Japan Soccer League (JSL) in 1965, along with today's Urawa Reds, JEF United Chiba, Cerezo Osaka, Sanfrecce Hiroshima and three other clubs ("Original Eight"). They had some successes during the mid-1970s, winning several Emperor's Cups and JSL titles and contributing several players to the Japanese national team.

The club relocated from Kodaira to Kashiwa in 1986, but it took a while to adapt to the new town, as they were relegated to the JSL Division 2 at the season's closing. They made it back to the top flight in 1989–90, but dropped back in 1990–91 and returned again in 1991–92. As the J.League advent had come too soon for them, the club abandoned to be a founding member of the newly formed professional league. The club joined the Japan Football League (called "former JFL") Division 1 in 1992, the second tier of the Japanese football hierarchy following the J.League.

Kashiwa Reysol (1993–)

The club changed its name to Kashiwa Reysol in 1993. Reysol added Careca of the Brazil national football team in the autumn of this year with the aim of winning the JFL champion for promoting to the J1 League. The club struggled, however, with the help of Careca and Brazilian manager Zé Sérgio, they secured the 2nd place in the JFL in 1994 and earned promotion to the top league.

Reysol debuted in the J1 League in 1995. They welcomed Akira Nishino in 1998 who was the former manager of Japan's Olympic team, Hristo Stoichkov of the Bulgaria national football team, and Hong Myung-bo of the Korea national football team. The club won the J.League Cup in 1999, their first title as Kashiwa Reysol.

However, next English manager, Steve Perryman, unsettled the team and the club struggled over the next several seasons. After finishing at the 16th place out of 18 clubs in 2005, the club lost the promotion/relegation play-offs against Ventforet Kofu, the 3rd place of the J2 League, and relegated to the J2 League.

A new manager, Nobuhiro Ishizaki, led an almost entirely new squad in 2006 and the club secured automatic promotion to the J1 League in the last game of the season.

The club was relegated again at the end of 2009. However, once they won the J2 League led by Nelsinho Baptista in 2010 and came back to the top flight, the club won the J1 League in 2011 with some talented footballers such as Hiroki Sakai, Junya Tanaka, Jorge Wagner and Leandro Domingues, and became the first Japanese club to win the second tier and the top tier two seasons in a row. The club qualified for the FIFA Club World Cup as the host nation's league champion and became semifinalist after defeating Auckland City and Monterrey.

For the period of 2010 through 2014, Reysol won six different titles for five consecutive seasons; the J2 League in 2010, the J1 League in 2011, the Emperor's Cup and the Super Cup in 2012, the J.League Cup in 2013 and the Suruga Bank Championship in 2014.
