Dragon is auspicious creature in Japan ( China as well) and it is known to bring good luck.
The art of drawing dragon in a single stroke can be traced back to 1950s when the art was very popular. Today, it is less common probably because people these days are less prone in hanging this drawing in their home. Will you?
