One of the most popular yuru-kyara in Japan is "Kumamon(くまモン)", which is a mascot of Kumamoto Prefecture. "Kumamon" is a combination of two words: "Kuma" is short for Kumamoto and "Mon" represents the local dialect that uses that word for the standard Japanese word for "things," or "mono(物)."
Here are Kumamon's images.
