There is an image of this cultivar on the Hosta Library. From the photo, it appears to be a small size hosta with dark green leaves and a very narrow, creamy white marginal variegation. It has pale purple flowers with lighter stripes.

This hosta from Japan has been found listed under several variations to this name including H. Alcebana Fukurin', H. 'Alcebana Kikurin', H. 'Alcebana Kikurin' and H. 'Kifukurin Alcebana'. It seems that all have green leaves with a white marginal variegation but may differ in other traits. 

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term kifukurin or ki fukurin as yellow edge(d) or yellow margin(ed) and the term fukurin as margined or edged.
