There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a medium size hosta with very wavy, pointed, light green leaves. This non-registered cultivar was originated in Japan. 

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term hime as small, mini, dwarf or princess.

MyHostas database says this could be H. 'Hime Setouchi'
