So, I've done a little research on the correct spelling of the red stone of "Aja". Indeed, the most common spelling of the word "Asia" in japanese is アジア while Araki writes it as エイシャ. However, according to the japanese wikipedia, エイシャ is just an alternate, exotic way to write アジア (more precisely, it's a spelling closer to the proper English pronunciation of "Asia").

The Aja reference is indeed a possibility and should be mentioned in the trivia.
