Aminobutyric acid
"Hatsuga genmai" () is brown rice that has been soaked in heated water until germinated. It is also known as GABA rice, as the germination process greatly increases its gamma-Aminobutyric acid content. It has a softer texture than ordinary brown rice and a pleasant fragrance. It is sold in Japanese supermarkets, but it can also be made at home. Some high-end rice cookers have a GABA rice setting to automate the process.
