This question already has an answer here:
Language and vocabulary differences between specific regions of Japan. Mostly used with specific dialect tag(s).
Applies to any question asking about differences in language between specific regions of Japan or definitions of specific words found in said region. This tag is usually used in conjunction with a tag specifying which dialect(s) the question is about.
But I when I looked at the "Related tags" for dialects, there were no tags for specific dialects mentioned, and it listed even tags with only one question in both dialects and that tag.
Did there use to be tags for specific dialects, which have since been deleted? If so, should the dialects wiki be updated accordingly?
