The prefecture is often alternatively pronounced "Ibaragi" by those who speak the regional dialect known as Ibaraki-ben. However, the correct pronunciation is "Ibaraki". According to the author of "Not Ibaragi, Ibaraki",[8] this is most likely due to a mishearing of the softening of the "k" sound in Ibaraki dialect.
