I do think Sanko is his first name because for one, it ACTUALLY is a first name and not a last name in japanese (meaning third child). Hajime Damemaru also has first name (Damemaru) as last. Also other characters refer to him as Sanko and not Zaha. As he's a teenager it would be weird if everyone addressed him by his last name.
