Hello @kh_mahdi14 and welcome to the community!
I think you meant that you want to purchase a European copy of XZ Premium which was made in Japan?
I think your best shot is to search for the phone on a European merchant website and contact the seller to make sure about the country of origin before you purchase.
It's not guaranteed that every phone sold in Europe was made in Japan though. And as far as I know, all the phones produced by Sony will undergo the same quality assurance process, regardless of the country of origin.
