If you’re interested in Kumamoto dialect, you may enjoy this. A lot of expressions are introduced with subtitles showing the dialect and equivalent expressions in standard Japanese. There’s no English so this video might be a bit difficult for beginners in Japanese but if you’ve been using Japanese for a while and can read the subtitles it may help you improve your facility in 熊本弁.
