well the point of IPA is that a symbol matches up to an internationally-agreed sound and /o/ is the close-mid back rounded vowel
however, what’s not listed is that it seems the elongation of a vowel in Japanese is suprasegmented - so the “doo” sound is closer to how you’d say the o’s in the (nonsense) phrase “do oozing” - a very subtle distinction from just “doo”
it’s possible that Japanese speakers could endolabiallize differently, or that they form the vowel closer to open-back than close-back like /《o̞》 / but I’m not an expert
I was mostly providing the IPA as a joke. It’s just copied from somewhere, I could probably track it back down and you could take it up with them. Certainly nothing in “door” or “hadouken” is anything close to an “oo” no matter how they’re all written.
