Nazo no Murasame-jou is an action game for the Family Computer Disk System.

The Mysterious Murasame Castle was one of the first games made for Nintendo’s Famicom Disk System add-on. It would have been released at the product’s launch, alongside The Legend of Zelda, but development issues forced the game to be delayed to seven weeks later. Murasame Castle was never officially released outside of Japan until it was released on the Nintendo 3DS Virtual Console in Europe, Australia, and North America in 2014.
