[6] His artworks include a "calculated and precise" nudibranch, folded from mirror-finished metal,[7][8] and an origami version of the Utah teapot, exhibited at the Tikotin Museum of Japanese Art in Israel.
[13] With Hiroya Tanaka, he is the author of the 2020 Japanese-language book コンピュテーショナル・ファブリケーション [Computational Fabrication: Design and Science of Origami and Tessellation].
[4] In 2009, Tachi won the Hangai Prize of the International Association for Shell and Spatial Structures (IASS), for his work on quadrilateral mesh origami.
[15] He was the recipient of the 2016 A. T. Yang Memorial Award in Theoretical Kinematics of the American Society of Mechanical Engineers, with Tom Hull, for their joint work on predicting the motion of rigid origami patterns when forces are applied to them in their flat state.
[16] Together with his coauthors Evgueni T. Filipov and Glaucio H. Paulino, Tachi won the 2020 Cozzarelli Prize in Engineering and Applied Sciences for their work using the Miura fold to generate stiff but reconfigurable tubular structures.
