This cultivar which has been on the market for a long time in Japan was originated by Dr. Fumio Maekawa but registered by Kevin Walek (Hosta Registrar) on his behalf in 2009. It is a sport of H. sieboldii which grows into a small size plant only 8 inches high and 22 inches wide with medium green colored foliage that has a white marginal variegation. The leaves are slightly rippled, ovate and dull on top. Pale to medium lavender, tubular flowers bloom from August into September. It sets seeds but the viability was not known at the time of registration.

According to The Hostapedia by Mark Zilis (2009), "According to Kenji Watanabe (1985), the names Chishima Gibōshi and Shirofukurin Chishima Gibōshi have been incorrectly used for Hosta 'Bunchōkō'."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term shirofukurin or shiro fukurin as white-edge(d) or white-margin(ed).

An article by Warren I. Pollock in The Hosta Journal (1991 Vol. 22 No. 1) states that, "The name on the label was 'Bunchuko', but according to W. George Schmid it should be 'Bunchoko'. This hosta looks like 'Ginko Craig'...H. 'Bunchoko' has dark purple blooms much darker and more handsome than 'Ginko Craig'...I confirmed this difference with our still blooming 'Ginko Craig' and also 'Princess of Karafuto' which is a 'Ginko Craig' look-alike."
