@SLR2009, I don't have Yama Nishiki but have had a few Higasayama's that I struggle to keep alive. I've just lost my 4th one only yesterday. There comes a time when you have to say enough is enough. If you purchase one of the two, I would love to see a photo of it, perhaps on the 'cheering ourselves up thread'. They have such pretty leaves. Both are very similar IMO to answer your question.
