“• シーサー(shīsā) = “Okinawan house guardian”
• 石敢當(ishi-gantō) is a good luck charm found frequently in Okinawa. According to Chinese tradition, demons cannot easily turn corners, so this charm is placed at dead ends, cul*-de-sacs, T-junctions, the corners of intersections, anywhere it can force demons to butt (當) their heads against stone (石) as they try to turn.”
