Suzaku has observed some cyclotron X-ray pulsars in the SWG (Science working group) phase. Suzaku detected the cyclotron feature in the lowest luminosity from A0535+26. In Her X-1, Suzaku measured new data points in the year-long trend of cyclotron resonance energy, and searched for the second harmonic structure. The RXTE observations of X0331+53 gave the second example on changing the resonance energy and indicated that the energy ratio of the 2nd and 1st cyclotron energies is apart from two. * )
