A seedling selection by Dr. Shuichi Hirao of Japan, this cultivar was registered by Peter Ruh of Ohio in 1997. It forms a large size (25 inches high) mound of floppy foliage. The leaves are slightly shiny on top and very shiny on the bottom with slight corrugation. This cultivar is part of the "Hirao Series" of hostas.

According to The Hostapedia by Mark Zilis (2009), "I often state that 'Hirao Supreme' is slightly less spectacular as a specimen plant than 'Hirao Majesty', but still worth growing. Also, it has been a better breeding plant."
