We present measurements of time-dependent CP asymmetry parameters in B0 → &phis;K s transitions. We reconstruct one neutral B meson decaying into a CP eigenstate and use the inclusive information of the remaining particles to determine the avor of the accompanying meson at its decay time. Using a data sample of 492 fb-1 collected at the Upsilon(4S) resonance with the Belle detector at the asymmetric KEKB accelerator, we reconstruct 202 B0 → &phis; Ks decay candidates with an estimated signal purity of 81.2% after vertexing, flavor tagging and other good vertex selection. From an unbinned maximum likelihood fit to the proper time interval distribution we obtain S=0.55+/-0.31statist ical+/-0.06systematic A=0.18+/- 0.20statistical+/-0.0 5systematic
