Re: Space Battleship Yamato 2199
^^^ I think you're referring to Admiral Isoroku Yamamoto. Slightly different spelling from Yamato but, yes, similar. He studied in the U.S. prior to the war, as did many Japanese officers at the time and he did feel the high command made a grievous error in attacking us the way they did.
I may appear unoccupied to you, but at the molecular level, I'm really quite busy.
