Kazuki Umemura is a rare breed!  He has recognised a niche that he can really empower in the BJJ community and is empowering them.  Too often in todays world we feel compelled to support everyone, and then as a result, end up being unable to support anyone.   Dive in with us as we meet and talk to the amazing organiser of the awesome fb group Kazuki's BJJ for 40+ (https://www.facebook.com/groups/bjjfor40plus)
