Hentai games are a genre of video games that originated in Japan and are typically characterized by sexually suggestive or explicit content, including portrayals of nudity and sexual activity. The word "hentai" is derived from a Japanese term that refers to sexually perverse or perverted desires and behaviors. Hentai games can range from visual novels with minimal interaction to more complex games with character customization and branching storylines. Some of these games are created specifically for adults and often feature anime or manga-style illustrations.
