The prefecture is often alternatively pronounced "Ibara''gi'' by those who speak the regional dialect known as Ibaraki-ben. However, the standard pronunciation is "Ibara''ki''. According to the author of "Not Ibara''gi'', Ibara''ki'',いばらぎじゃなくていばらき
'Ibaragi ja Nakute Ibaraki''/ref> this is most likely due to a mishearing of the softening of the "k" sound in Ibaraki dialect.
