gohei
Gohei (御幣), aka onbe (御幣) or heisoku (幣束).
A wooden wand traditionally decorated with shide (zigzag paper streamers), though in the past it was made with rectangular strips of paper. It is used for Shinto rituals to cleanse negative energy or bless.
Notable characters with gohei include Hakurei Reimu, Kochiya Sanae (who is often seen using an old-fashioned gohei with a single rectangular strip of paper on the end) and Yae Miko (who uses the more modern, zigzag paper strip gohei).
