... I just noticed these are all survivors... (Although didn't Haruna technically survive, too? At least, in the same way Myoukou did?)
Suddenly, a bit more depressing.
Not quite. TECHNICALLY Taigei/Ryuuhou (Floating scrap in Kure harbour, but still afloat, just never repaired) survived, she was burnt out and her flight deck pretty wrecked, but she DID technically survive for a year before being scrapped in place.
Haruna didn't survive, she was sunk in her moorings in july 1945, then raised and scrapped in-place in 1946.
The difference between Haruna and Myoukou are kind of slim, there. It's like arguing that Myoukou is 5 grains of sand short of being a pile.
It's a case of "Floating/Non-Floating". Arguably, Ryuuhou was in worse shape than Jun'you, and Myoukou, but still floating;
Ryūhō was attacked by Task Force 58 aircraft on 19 March near Kure, suffering hits by three 500 lb (227 kg) bombs and two 5.5-inch (140 mm) rockets. The damage was severe: the flight deck bulged upward between the two elevators, the No. 1 boiler was punctured by a bomb fragment, the stern settled six feet (2 m) into the water, and a raging fire broke out. Twenty crewmen were killed and 30 were wounded. Upon returning to Kure on 1 April, Ryūhō was considered to be a total loss. She was struck from the Navy List on 30 November and scrapped in 1946.
But, she was still afloat, so by definition, while useless and irreparable, she still survived. By the same definition, Haruna didn't survive because she was sunk. While raisable, it would have taken a long time to do, along with resources Japan just didn't have left.
The US proved it could be done, when they raised Oklahoma (never repaired, sank under tow on the way back to the US Mainland for scrapping), West Virginia, and California (Both returned to service). Of the 8 ships in Battleship Row, Oklahoma and Arizona never returned to duty, one from costs of repairing, the other from being wrecked entirely.
So really, it all comes down to semantics and strict definitions. By the stricter "Only floating counts", Haruna didn't survive, but by the definition of "Usable in some form", you can argue she did, even if it was literally as a half-sunken pile of scrap thanks to air-raids wrecking batteries.
