It is a dream to train on. Really good IJF approved mats from Essimo.
The flags are just a variety of flags for countries producing top level judoka (no offence to countries we have missed out, as plenty of other countries produce amazing players), although the Brazil flag is there to represent the next Olympic cycle, but in turn will probably attract some BJJ instructors to rent the place out. A couple of local Russian judo/sambo players also like the fact we have put a Russian flag in there.
Flags from left to right: South Korea, France, Brazil, Great Britain, Japan, Russia, Greece.
