Japanese dialects
Hyōgo Prefecture is the largest prefecture in Kansai, and there are some different dialects in the prefecture. As mentioned above, Tajima-ben () spoken in northern Hyōgo, former Tajima Province, is included in Chūgoku dialect as well as Tango-ben. Ancient vowel sequence /au/ changed in many Japanese dialects, but in Tajima, Tottori and Izumo dialects, /au/ changed . Accordingly, Kansai word "ahō" "idiot" is pronounced "ahaa" in Tajima-ben.
