Hikone's official mascot Hiko-nyan appears three times daily for a 30-min. show: 10:30 am and 1:30 pm in front of the main castle tower (tenshu) and at 3:00 pm outside Hikone Castle Museum.

According to legend, one day, Ii Naotaka, the third lord of Hikone Castle, was doing falconry in Tokyo and was near a temple when he saw this cat raising its paw. He was led inside the temple where he was able to rest inside. A major thunderstorm ensued, and the cat saved him from getting wet.
