How was the Great Pyramid Built Unknown by Japanese

During research expeditions to the pyramids of Giza, Egypt in 1978, we were able to simultaneously film a group of construction engineers and research scientists from Japan (Nippon Corporation) who began to undertake a reconstruction of the Great Pyramid on a smaller scale. This film is one of the few documents of this attempt to use basic tools (basic tools, ramps, local labor force) to create sophisticated fittings of the limestone blocks. In the end, it proved too difficult to continue with primitive methods and they resorted to modern means to create their small model.
