The motif that primarily represents thunder and lightning with meandering straight lines is referred to as "Rai-mon" or thunder pattern. This pattern has often been adorned on costumes worn during performances of vigorous roles in Noh theater and is prominently featured on Noh costumes from the Momoyama period onwards. While there are variations like the swirling vortex depicted within a square, this motif has ancient roots in Chinese designs.
