The Adagio Miscanthus you mentioned is a great selection, I am not as familiar with ‘Yaku Jima’. But if your looking for alternatives, try Pennisetum (a.k.a. Fountain Grass) and a smaller variety is known as ‘Hameln’. Or, Calamagrostis x ‘Karl Foerster’ a more upright selection.

warm season grasses that have been using in park for covering the earth surface, can it be called ornamnetal plant? or can it be transformed as ornamental plant…with the help of other landscape element..
I would like to know what are the criterias of ornamental plant…?
Not to my knowledge. It may even reduce the cost as they tend to be low maintenance and require minimal water (some species). Also, I understand that most ornamental grasses only need to be cut back once a year.
