True Vermilion, Monkey Demon Guinomi

Created based on the legend of the monkey demon (Saruoni) passed down in the Oku-Noto region
One theory holds that the "saruoni" (monkey demon) referred to wheel-turners who crafted bowls, or to "tatara" artisans — suggesting lacquerware production has taken place in Oku-Noto since ancient times.

By painting an oni (demon) inside the guinomi sake cup, a warding charm was added — swallow the demon along with your sake!
