Yamato

Part of the foredeck and port side of the Yamato were reconstructed to full scale for the exterior scenes. As the Japan Building Standards Act interfered with re-creating the ship's entire superstructure, images of a one-tenth scale model of the Yamato at its namesake museum in Kure were used in post-production.

The ship is seen firing salvos from its main batteries aimed at approaching US aircraft on several occasions, while lots of the crew are visible on deck, manning the light AA guns as well as performing other duties. While the big guns were in fact used fending off aircraft, at least during the last battle off Okinawa, the shock wave from the blast of the nine 460 mm barrels (the biggest ever on a warship) could kill or severely injure an unprotected sailor, it was therefore forbidden to remain on deck on such occasions.
