granny knot; reef knot tied with a left loop
A knot tied by making a left loop first, often contrasted with 男結び (right loop first). In English knot terminology, this is a granny knot, though some sources may call it a reef knot or square knot depending on tradition. The Japanese distinction is based on the starting loop direction.
