During my research to the origin of the Fushimi Cube, I came across more origami works of Dr. Koji Fushimi 伏見 康治 – and his Origami Koji Fushimi Tato. His name is sometimes spelled Kôdi Husimi. He was a theoretical physicist and was also interested in mathematics and origami.

Origami Fushimi Tato

Today I would like to show you a simple, but beautiful envelope, the Origami Koji Fushimi Tato. You can find the diagram to this model in the book “Origami Omnibus” by Kunihiko Kasahara, page 25. This model was first published in the book “The geometry of origami – 折り紙の幾何学 origami no kikagaku” in 1979 and reprinted in 1984 by Koji Fushimi (Husimi) and Mitsue Fushimi (Husimi) [his wife]. The original book focused on mathematics and geometry but also origami with polyhedrons, cranes and tato.

What’s special about this model?

With only 6 steps you transform a flat square piece of paper into this interesting origami tato (たとう) – a kind of envelope. It is pleasing from the mathematical point of view as well as from the esthetical one. If you shine light through the finished model, there will be layers with 2, 3 and 4 layers of paper with a windmill pattern.
