This cultivar is a seedling of H. venusta × H. 'Komame' which was originated by Mr. Kitahara in Japan. It is a miniature size plant.

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term otome as maiden, 'Otome Gibōshi' or H. venusta.

An article by Akira Horinaka in The Hosta Journal (2006 Vol. 37 No. 1) says,  "...'Yakushima Otome' was hybridized by Mr. Kitahara...in Tokyo. It was produced from H. venusta...and 'Komame', a very small form of H. 'Yakushima Mizu' found in Kyushu."

Horinaka added  "A variety referred to provisionally as "Kairyo Hinsyu" is an improved cultivar of 'Yakushima Otome'...It is a pretty miniature hosta that has leaves...[nearly 1¼ inches] long with a creamy white center and a clean and narrow green border. When it is increased, it will be given a permanent cultivar name."
