There is no deal in EU or Japan. Trump is con artist. A serial fraudster. He is not bound by any court or the rule of law or congress. He is a proven bad faith actor. The US is a bad faith actor.
These "deals" with Japan and the EU aren't worth the ink used in the signature. EU and Japan know this as does the US. This is three lying parties, all knowing everyone is lying, buying time to de-integrate economies gracefully.
Nobody is fucking investing in Trump's America. Everyone is moving as fast as possible to divest from the US to domestic for strategic needs and reliable trade partners for everything else. No one would risk further entanglements with a bad faith actor bound by nothing but Antisocial Personality Disorder and a sexual desire for children.
