The Hall coefficient in the low-temperature tetragonal phase and the midtemperature orthorhombic phase of La1.88-yYySr0.12CuO4 (y=0,0.04) single crystals is measured under high magnetic fields up to 9 T in order to investigate the detailed behavior of the transport properties at low temperatures in the stripe phase. When the superconductivity is suppressed by high magnetic fields, the Hall coefficient has negative values in low temperatures, and the temperature region of the negative values spreads as increasing magnetic fields. This result indicates that the Hall coefficient in the stripe phase around x = 0.12 is a finite negative value, not zero.
