John Finnemore, Peeps at Many Lands: Japan
“ As a Japanese writer says: "Oni fears the sword-blade of the sweet flag, so that its leaves are everywhere. They are upon the festal table; they hang in festoons about the house, and all along the eaves. Boys wear them tied around their heads, with the white scraped fragrant roots projecting like two horns from their foreheads. So, and with the noise of bamboo horns, they frighten away the ogre god. For he fears horned men, and he dares not enter a house where so many swords hang from the eaves." ”
