ミノワマン
The sport of mixed martial arts originally had no weight classes, and martial artists of different styles and sizes were drawn together to prove which martial art is most effective in unarmed situations. By the early 2000s, weight classes were introduced and became mandatory in many countries. However, Japan became a bastion of openweight fights, nicknamed "freak show fights," with fighters such as Ikuhisa Minowa and Genki Sudo commonly facing much larger opponents.
