Dwarf Ardisia japonica cultivar name

[scarecrow]

Is there a cultivar name for the dwarf Ardisia japonica being passed around in bonsai circles? It's too small to be the species and it doesn't look the same as Chirimen or Angyo Pixie. I think it's the same one that appears in this blog post: https://bonsaitonight.com/2015/12/18/more-shitakusa-from-taikan-ten/. Thanks for you help.
