  The Wide-band All-sky Monitor (WAM) is a function of the large lateral BGO
shield of the Hard X-ray Detector (HXD) onboard Suzaku. Its large geometrical
area of 800 cm^2 per side, the large stopping power for the hard X-rays and the
wide-field of view make the WAM an ideal detector for gamma-ray bursts (GRBs)
observations in the energy range of 50-5000 keV. In fact, the WAM has observed
288 GRBs confirmed by other satellites, till the end of May 2007.
