Considered by most to be the “father of modern origami“, Akira Yoshizawa created many artistic models and invented the system of diagramming we now use as standard. He also, it seems had a wonderful sense of humour:

This model is as much a character study as a comment on Japanese society, and I must admit to a giggle when I first found this model nestled near the back of Yoshizawa’s seminal work “Creative Origami”.

Initially, the model is folded asymmetrically, then as features emerge it is obvious this character is “fully equipped” and ready to rumble (although I was sure sumo usually wore some form of ceremonial “nappy” – for some reason Yoshizawa decided to omit that detail).

A simple fold that would benefit from thinner paper (the shoulders and neck were very difficult to fold with an A4 copy paper square). Quite cute however and I would imagine shocking in the day (but these days we would probably suggest steroid abuse will do that to a man 😛 )
