We obtain a new attenuation distance-relation of seismic intensity for Japan using the strongmotion data-base constructed by Kanno et al.（2006）. We also obtain additional correction terms corresponding to the site amplification, anomalous seismic intensity and event type（plate-boundary or intra-slab）. Although we used strong-motion data until the 2003 Tokachi-oki earthquake, the attenuation relation agrees to observed records during recent large earthquakes.
