        Okay, I've tired of this.  I asked a friend,
all Japanese apartment
complexes are called "Mansions"...  Sorta like "Terminal Hotel" 

That's true.  But Maison Ikkoku is "Maison", not "Mansion."

        BTW: an apartment itself is called a "One Room Apartment"

Depends on the place.  I've usually just seen "apaato" as the generic, 
and then 2DK or 1DK or whatever for the type of place.
