A method of culturing human induced pluripotent stem cells includes inoculating human induced pluripotent stem cells in a culture medium at an inoculation density of 1.0×104 to 1.0×106 cells/cm2 in a culture vessel and subjecting the human induced pluripotent stem cells to two-dimensional culturing. A method of producing cerebral organoids includes culturing a culture of the human induced pluripotent stem cells obtained by the method of culturing human induced pluripotent stem cells in a culture medium containing a BMP inhibitor and a transforming growth factor β (TGFβ) inhibitor to form cell aggregates, culturing the cell aggregates in a culture medium containing a Wnt signal transduction pathway potentiator and an extracellular matrix, and subjecting the culturing obtained in the culturing the cell aggregates to spinner culturing.
