The maneki-neko (Japanese: 招き猫, literally 'beckoning cat') is a common Japanese figurine (lucky charm, talisman), usually made of ceramic in modern times, which is often believed to bring good luck to the owner. The figurine depicts a cat (traditionally a calico Japanese Bobtail) beckoning with an upright paw, and is usually displayed—many times at the entrance—in shops, restaurants, pachinko parlors, and other businesses. Some of the sculptures are electric or battery-powered and have a slow-moving paw beckoning. The maneki-neko is sometimes also called the welcoming cat, lucky cat, money cat, happy cat, or fortune cat in English.
