This non-registered cultivar was originated by Shinya Fukatsu of Japan. According to an article by the originator in The British Hosta and Hemerocallis Society Journal (Autumn 2019) this is a medium size hosta of unidentified background. The green foliage has a yellow-misted medial (center) variegation and whitish colored backs. Its petioles have dark purple spots and the leaves have a convex curve later in the season. The densely arranged flowers bloom on scapes in good proportion to the clump.
 

Named for the person noted for establishing the Japanese tea ceremony in the 16th century.
