“Naru-Kami’s themes are offerings, excellence and the arts. Her symbols are needles, thunder & lightning and trees. In Japan this Goddess embodies the odd combination of weather magic and artistic inspiration. Perhaps this is how we come by the phrase ‘struck by lightning’ to describe a flash of creativity. In local tradition, any place hit by lightning is thereafter sacred to Naru-Kami. She is also the patroness of trees.
Participants in the Hari-kuyo [which actually takes place in February…], known as the Mass for Broken Needles, honor the ancient art of sewing by bringing broken or bent needles into temples and later consigning them to the sea with thankfulness.
We can translate this observance into a blessing for any creative tool, be it a paintbrush, clay, a musical instrument or even a computer! Take the item and wrap it in green paper (which comes from this Goddess’s sacred trees). Leave it on your altar or in your workroom for the day so Naru Kami can fill it with her inspiring energy.
For those who sew, crochet or knit, definitely take out your needles today and leave them in a special spot with an offering for the Goddess, cakes or tofu being customary. At the end of the day, take these up and use them in your craft to honour Naru Kami and commemorate this holiday with your skills.”

Patricia Monaghan says that “the Japanese thunder Goddess was the protector of trees and the ruler of artisans. Wherever She threw a bolt, that place was afterward considered sacred” (p. 227). All the other sources I could find pretty much stated the same information.
