We discuss the effect of such high density around red supergiants caused by the wind acceleration on Type II supernova properties. We find that early supernova light curves can be significantly affected by the dense circumstellar medium caused by the wind acceleration. Light curves with the dense circumstellar medium match to those of some observed Type II supernovae better. Our result indicates that the immediate dense environment of Type II supernova progenitors could be significantly influenced by wind acceleration.</span></p>
