Does miso soup actually qualify under a strict five-ingredient count, and which version do you use?

Miso soup keeps coming up in conversations about minimal-ingredient cooking, and I find myself genuinely uncertain whether it fits a strict five-ingredient rule or whether it only seems minimal because the components are so familiar. The counting gets complicated fast. Dashi alone can mean kombu and katsuobushi as two separate ingredients, or it can mean a prepared dashi stock as one, and that choice changes the whole picture. Then you have the miso paste, tofu, wakame, and maybe a garnish like scallion. Depending on how you count, you are either well within five or already over, and the answer seems to hinge entirely on whether you treat dashi as a single unit or as its component parts. I am curious whether anyone has a version they consider genuinely complete at five ingredients under a consistent counting rule, and what that rule actually is. The soup itself is interesting because even a stripped-down version feels like a finished dish rather than something missing a component. That quality of feeling complete despite the constraint is exactly what seems worth capturing here, but I want to understand how people are actually drawing the line before assuming it belongs on this list.
