I don't think Aespa sold 200k+ in oricon , i think it's billboard japan sales. Those sales includes album purchased by international fan and shipped from japan (oricon only count album shipped within japan).
For NJ i don't think the comparaison make much sense as Supernatural was released in the same way as their Korean release. It's quite normal that an album released everywhere will sold less in japan that albums only released in japan (if i'm correct about the release ).
