The Yoshimoto Cube is a polyhedral mechanical puzzle toy invented[1] in 1971 by Naoki Yoshimoto (吉本直貴, Yoshimoto Naoki), who discovered that two stellated rhombic dodecahedra could be pieced together into a cube when he was finding different ways he could split a cube equally in half.

Yoshimoto first introduced his cube in 1972 at a solo exhibition entitled "From Cube to Space", and later developed three commercial versions.

1 was included in the Museum of Modern Art's permanent collection.

The unfolded cube can be dissected and reassembled into two stellated rhombic dodecahedra, each of which comprise half the volume of the original cube, making it a kind of three-dimensional dissection puzzle.
