I'm not sure how any of that makes much difference since Japanese armies almost never used them against foreign enemies. Maybe if the Mongols actually managed to launch a sustained campaign in Japan things would have been different, but that didn't exactly happen.

Interestingly, the one time that katanas would see use in the battlefield would be with yumi-armed samurai. Katanas would be a good backup weapon when the enemy is too close to employ bows. Otherwise, naginatas and yaris would be a lot more effective.
