is a traditional Ryukyuan decoration, often in pairs, resembling a cross between a lion and a dog, from Okinawa mythology. People place pairs of shisa on their rooftops or flanking the gates to their houses. Shisa are wards, believed to protect from some evils. When in pairs, the left shisa traditionally has a closed mouth, the right one an open mouth. The open mouth wards off evil spirits, and the closed mouth to keeps good spirits in.
