About This Trend
古古古古米 refers to a type of Japanese rice that has been stored for four years, with the number of '古' (meaning old) indicating the number of years it has been stored.
The 古古古古米 is currently trending due to Japan's rice shortage, which has led to the release of reserved rice, including the 古古古古米, with the government announcing an additional release of 200,000 tons of reserved rice.
