This non-registered cultivar was introduced by Jeroen Linneman of the Netherlands in 2012. It is a medium size, stable sport of H. 'Valley's Future'. The foliage is narrowly ovate and dark green with a yellow marginal variegation which turns white later in the season. Leaf backs are white.

The name is Japanese for a type of relay race where the runners hand off a cloth sash called a tasuki.
