It’s easy. W is a vowel in Welsh. It sounds similar to ö in German and it can be modified as ŵ to elongate the sound such as in the word dŵr which means water.
Wrwgwai or Wcrain (for example) are the natural way to spell those countries using the Welsh alphabet. Its a highly phonetic language believe it or not.
Having read your comment I’d like your views on “Wrwgwai” - the South American country of Uruguay.

In English it is literally called ‘double u’
Even tho it’s more like a double v. Always struck me as odd.
Afaik, comes from Latin that had no “U” and “V” was both vowel and consonant until some point in time.
