This same pattern appears again on the Pierrot website with a different name and pattern photo. It is called 28-36 on the pattern website and オーガニックコットンのキャスケット (Ōganikku kotton no kyasuketto) in the pattern PDF. The patterns are identical aside from name and recommended yarn, however. The yarn in the first version (Pierrot New Cashmere 100) has been discontinued; the recommended yarn in the second version is Pierrot Organic Cotton.
