This model was published in Tanteidan Convention 15. This is a annual publication by the Origami House, which show case original origami models by Japanese and design all over the world.
The Cerberus is a mythical creature described in the Greek and Roman literature as a multi-headed hound which guards the gate of the underworld. The most popular version of the Cerberus is a 3 headed dog, but there are others sources claiming to have more.
The Cerberus model designed by Satoshi depicts the 3 headed version. Therefore compared to other models, it is 3 times more difficult as every details on the head design would have to repeat folding 3 times!
I am using brown paper to fold this model. Do not be folded by the boring outlook of this humble papyrus use mostly for packing parcels in local post office. It turns out to be more resilience to the folding torture which this complex model have to offer. As usual, the 31 steps are basically ‘precision creasing’.
Model collapsing in the next 6 steps is not much of a challenge to many by now.
By the next 40 steps, the paper has reduced to only about 1/8 of the paper size with all of them folded nicely in between the layers.
