A visual novel (ビジュアルノベル bijuaru noberu) is an interactive game genre, which originated in Japan,featuring text-based story with narrative style of literature and interactivity aided by static or sprite-based visuals, most often using anime-style art or occasionally live-action stills and some video cutscenes, As the name might suggest, they resemble mixed-media novels. source(Wikipedia)
