Dengeki Novel Prize

The Dengeki Novel Prize (Japanese: 電撃小説大賞, Hepburn: Dengeki Shōsetsu Taishō) is a Japanese literary award handed out annually (since 1994) by the Japanese publisher ASCII Media Works (formerly MediaWorks) for their Dengeki Bunko light novel imprint. The contest has discovered many popular and successful light novelists, like Kouhei Kadono and Yashichiro Takahashi. Originally called the Dengeki Game Novel Prize, the name was changed in 2003. The main Dengeki Novel Prize awards consist of the Grand Prize (¥3 million), Gold Prize (¥1 million) and Silver Prize (¥500,000). In addition to the money received, the winning novelists get their work published under Dengeki Bunko with the addition of an artist for the illustrated aspects of the light novels.
