Sumo Jet Black Chonmage. Please Try It Before You Buy! No Refunds!! Please Leave Reviews Below And Concerns On My Page. "Osu No Seishin". The chonmage is a form of Japanese traditional haircut worn by men. It is most commonly associated with the Edo Period and samurai, and in recent times with sumo wrestlers. It was originally a method of using hair to hold a samurai helmet steady atop the head in battle, and became a status symbol among Japanese society. A traditional Edo-era chonmage featured a shaved pate. The remaining hair, which was long, was oiled and tied into a small queue which was folded onto the top of the head in the characteristic topknot. In modern times, the only remaining wearers of the chonmage are sumo wrestlers. This style of chonmage is slightly different, in that the pate is no longer shaved, although the hair may be thinned in this region to allow the topknot to sit more neatly.
