This report describes the recent results of the beam commissioning of the ATF at KEK. Recent progress on the studies on production of low emittance beam, multi-bunch beam operation and development on beam instrumentation are discussed. So far, a horizontal emittance of 1.7 {+-} 0.3 nm was measured with wire-scanners in the extraction line and with the horizontal spatial coherence using an SR interferometer. In addition, a vertical emittance of 15 {+-} 7.5 pm was measured with a laser wire and the SR interferometer in the ring and 5 wire scanners.
