Disclosed is a method for producing an amino-acid-rich yeast which contains a free amino acid at a high concentration. Specifically disclosed is a method for producing an amino-acid-rich yeast, which is characterized by subjecting an yeast in the stationary growth phase to the liquid culturing under conditions where a liquid culture medium has a pH value of not lower than 7.5 and lower than 11. Also specifically disclosed is a method for producing an amino-acid-rich yeast, which is characterized by adjusting the pH value of a liquid culture medium for an yeast in the stationary growth phase to a value not lower than 7.5 and lower than 11 and subsequently culturing the yeast in the liquid culture medium. In the methods, the yeast may be
