I don't speak Japanese but this is either the Ise or her sister Hyuaga. I'm inclined to believe it's the former but if anyone knows otherwise, please correct me. At about the ten minute mark may be the unfinished carrier Amagi. Interesting zebra camouflage on the turret of another BB (12 min). I think the Haruna?
The capsized carrier is indeed the Unryu class Amagi. However she WAS commissioned on 10 Aug 1944 and then worked up in Japanese waters. Her history and fate can be found here. Imperial Flattops This film footage of her, along with many stills, date to the period of her salvage in 1946/47. As a starting point anything easily removable, like gun mounts, was removed to make righting the hull easier. Hence the "incomplete" appearance. Sister ship Unryu was sunk in Dec 1944, while Katsuragi which was also completed, was damaged by bombing in July 1945 while moored near Amagi, but survived to work as a repatriation ship early Post war.
