Discovered in the Oze area of Japan, this non-registered cultivar is of unidentified parentage but thought to be related to H. rectifolia. It is a miniature size plant about 5 inches tall with a spread of around 12 inches. The foliage is medium green in color with a creamy yellow marginal variegation. Its leaves are wavy, elliptic, slightly cupped and come to a blunt tip. White flowers bloom in August on scapes up to 13 inches tall.

According to The Hostapedia by Mark Zilis (2009), "This is not the same 'Oze' referred to by Schmid 1991, p. 88), who considered the name "Oze Gibōshi" a synonym of Hosta rectifolia. Plants of 'Oze' that I observed in Japan were different from any known form of Hosta rectifolia."
