Yokohama derby

The Yokohama derby (横浜ダービー) is the local derby in Yokohama, Kanagawa, Japan, between fierce city rivals, formerly Yokohama Marinos and Yokohama Flügels, and currently Yokohama F. Marinos and Yokohama FC.

History
Nissan Motor FC was founded in 1972 by the employees of Nissan. The club's name was changed to Yokohama Marinos in 1992 due to its decision to go professional. All Nippon Airways SC was founded in 1964 by the employees of All Nippon Airways. The club's name was changed to Yokohama Flügels in 1992, also after deciding to go professional. Flügels then merged with Marinos to become Yokohama F. Marinos in 1999, but many Flügels fans refused to support the new combined effort and created their own club, Yokohama FC.

The Yokohama derby is known as one of the most dangerous derby matches in Japan. At the derby on 11 August 2007, the Marinos' ultras were arrested after lynching FC's supporters. On the 10 October 2012 derby, the FC's ultras posted expletive choreography, resulting in a permanent ban from all of FC's matches. On the 11 July 2018 derby, FC's ultras refused to hold a moment of silence for the victims of the 2018 Japan floods and continued to sing chants.
