We report the effect of magnetic field on the transport properties in the exotic heavy fermion PrFe4P12. The temperature TP of the resistivity maximum, ca. 13 K at zero field, shifts almost linearly with increasing field, correlated with the reduction of the effective mass determined from the de Haas--van Alphen (dHvA) measurement. The resistivity in 8 T shows a huge anisotropy with respect to the magnetic field direction.
