When it comes to ULTRA SUPER COMPLEX human form origami model designer in Japan, I would say Hojyo Takashi is among the best. His design now only captured the the human form in good proportion and anthropometric ratio, but also include much details to the human features.
The Maitreya model is a very early design published in Origami Tanteidan Convention Book Vol. 4 back in 1998.I first folded this model almost 10 years ago and was really excited and amaze on the intricacy of the design then. Hojyo more recent design has even move up another level now, but these model mostly are released in CP format. Hence to fold Hojyo’s model, the folder needs to be very experienced. (follow this link to see more of Hojyo’s work).
The Maitreya model is considered quite an easy model to fold. Folding the first 87 steps to get the base is less than 2 hrs job. Although there is a slight difficulty at step 17 and 18 (diagram seem to be misprinted), but it is not difficult to execute the necessary fold judging from the diagram before and after. Once finished step 94, this is what you get.
