Rubik's Cube was invented by Hungarian architecture professor Erno Rubik in the 1970s before a company in the US turned it into a hit product in the 1980s.
More than 100 million cubes were sold worldwide in the first two years.
It was an instant hit in Japan where more than four million were sold in the first eight months after it went on sale in July 1980.
The new tiny cube was shown this week at an exhibition in Tokyo organised by the Hungarian embassy, which also includes an artwork made with Rubik's Cubes.

The exhibit will run through until November 9.
Norbert Palanovics, the Hungarian ambassador to Japan, said he tells anyone who will listen about the Rubik's Cube because it embodies the small, simple but smart qualities of his country.
'The Rubik's Cube is part of our everyday life here in Japan, too, and inspires everyone,' he said.
