This species comes from Honshu Island in Japan and was found by a man named Takahashi in 1942. It grows to a medium size about 12 inches high and 26 inches wide with lightly rippled foliage of average substance. The leaves have slight purple to red dots on the petioles. Purple flowers with purple dotted anthers bloom from August into September followed by some viable seeds.

The Hostapedia by Mark Zilis (2009) says, "...from Mt. Ibuki in central Honshu Island in Japan... 15" high...mound of shiny, green foliage...ovate-shaped and very shiny on the underside...slight purple-red dots on the petiole base; purple flowers emerge from dark purple buds in August."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Related to H. sieboldii although the leaf shape is different...A long raceme of flowers. The anthers are also purple-dotted. Sterile bracts clasp the scape."
