Does Sony sie belong to an American company or a Japanese company?

SIE is now a completely American company, and its Japanese branch is even named "SIE Japan", which means that Japan is no longer the main body of its company, and its business is completely around the United States. This is somewhat similar to the relationship between Sony and Columbia Pictures. Although Sony is still a Japanese equity brand, Columbia Pictures is still an American company rather than a Japanese company.
