1. A failure determination device comprising:
acquiring circuitry to acquire pressure values of air springs from pressure sensors, the air springs being provided to a bogie included in a vehicle to support a vehicle body included in the vehicle, the pressure values being values measured by the pressure sensors, the pressure sensors measuring pressures of air inside the air springs;
compensating circuitry to perform, depending on a position of the vehicle, compensation of the pressure values of the air springs acquired by the acquiring circuitry; and
determining circuitry to determine, based on the pressure values of the air springs compensated by the compensating circuitry, whether any failure occurs in the air springs.
