Urawa Reds Official Supporters Club is the official supporter-club system of Urawa Red Diamonds. It was established in 1991, before the launch of the J.League, and Urawa describes it as one of the league’s oldest and most distinctive supporter organisations.
Supporters register in groups of three or more under their own club name, with each registered group formally certified by Urawa Reds. The system is designed around supporter-led organisation, flags and community connections rather than conventional membership benefits.
The organisation remains active for the 2026/27 season under the club’s “IN RED WE CONNECT” campaign.
