While vacationing in Osaka, I noticed a type of grass in raised beds. I can't remember much about it, but I think it was pretty popular. It may have been about six or so inches tall, but the distinguishing feature was that the ends curve over. I did hear at the time that it only grows to a certain length, preventing the need for mowing. It was quite unique but I can't find any more information about it. Any assistance in this would be appreciated.
