This seems to contradict what we know about だか: [never in a main
clause](https://japanese.stackexchange.com/a/13468/30454). On the other hand,
all of these utterances appear to be from people/fictional characters who
speak [茨城弁](https://ja.wikipedia.org/wiki/%E8%8C%A8%E5%9F%8E%E5%BC%81).
However, I haven't found this recorded as a 茨城弁 feature in Wiki articles or
elsewhere. So is it 茨城弁?




It's definitely dialectal, but according to [this
page](https://www.weblio.jp/content/%E3%81%A0%E3%81%8B), it's not specific to
茨城. To me, this type of sentence-end だか is stereotypical
[いなか言葉](https://japanese.stackexchange.com/a/23691/5010) that is associated
with no particular region in Japan. (That is not to say だか is an imaginary
thing.)
