Increased luck, increased fortunes for the family
With its lazily curving, symmetrically ascending waves, the tatewaku motif is reminiscent of the upward movement of steam and represents increased luck and family fortunes. During the Heian Period (794-1185) it appeared on clothing and furnishings as one of the traditional yushoku patterns for the nobility. Some designs combine the tatewaku motif with clouds, flowers, and animals. This particular pattern is known as the Shosoin Pattern and features birds and flowers, which are heralds of good news.
