It is like a disease to think that an invincible status has been achieved after being satisfied with the past successful operations.

If a war breaks out with the United States, the navy will have to put all its strength into interceptive operations, so... massive sea-borne supplies might be momentarily interrupted.

In the first six to twelve months of a war with the United States and Great Britain I will run wild and win victory upon victory. But then, if the war continues after that, I have no expectation of success.

I entered the navy with the great ambition of becoming a naval soldier and going to war. Either I die from this festering wound - because I refuse to have my arm amputated - or I recover from it and continue being a soldier. I have a one-in-two chance, and I shall bet my life on it!

If we are to have a war with America, we will have no hope of winning unless the U.S. fleet in Hawaiian waters can be destroyed.

Never tell anyone outside my staff that the Submarine Force and the First Air Fleet were responsible for the failure at Midway. The failure at Midway was mine.
