Union Jiu Jitsu

Gi and No-Gi sit at the center of Union Jiu Jitsu in Chatham, Ontario, Canada, placing two closely related grappling categories alongside one another. Gi identifies the uniform-based side of jiu-jitsu, while No-Gi identifies the category practiced without that garment, giving the name a clear two-format emphasis. For a beginner, the distinction helps frame how clothing can affect grips and movement at a broad level, without changing the record's focus beyond these two labels. For a competitor, Gi and No-Gi are also useful category markers for understanding the separate rule and attire contexts commonly associated with each format. Union Jiu Jitsu is therefore defined here by its Gi and No-Gi focus and by its Chatham location in Ontario, Canada, with both disciplines presented as the central identifiers of the martial-arts record.
