What is the formal linguistic term for a **prepositional object** in Japanese?

My native speaker sources suggested "前置詞句の目的語" and "前置詞句の補語", but they
admitted to being unsure.




I've heard ''前置詞の目的語''.  
It means the partner of the prepositional, not a role in a sentence.  
  
''前置詞の目的語'' can be used even when the prepositional phrase is not regarded as
a kind of the object in the sentence.  

> I'm waiting for _her._  
>  I made a cake for _my children_ with _her._  
>  I'm interesting in _ethnic food_.  
>

These words in italics are all ''前置詞の目的語''.
