I do believe all true koryu-budo (Japanese classical martial arts) do not believe in competitions. The only competition they have is fight to the death, shinken-shoubu (duel with real swords).

One of the uniqueness of Aikido is that Aikido is gendai-budo (Japanese modern martial arts) and still hold true to the no competitions rule. Any movement or any technique must be respected as lethal and not be toyed or played with, for they might cause a fatal result.

Actually, in my opinion is that the philosophy of Aikido is not actaully unique, but it is actually universally true to all true budo/martial-arts. It is even universally true to life.
