"Sorajiro(そらジロー)" is a mascot of weather reports of NTV(日本テレビ). Some people regard him as a kind of "yuru-kyara(ゆるキャラ)".
"Sorajiro" is a combination of two words: "Sora" means sky in Japanese, and "jiro" is a common boy's name, which is given to a second son in Japan.
He appears on weather reports of NTV with a weather forecaster. For example, Sorajiro appears on the weather report of "news every.（ニュース・エブリィ）", a evening news program of NTV, with Minoru Kihara(木原実), a weather forecaster.
