After Leyte, the IJN had Kongo, Haruna, Ise, Hyuga, Nagato, and Yamato. Haruna, Ise, and Hyuga died at their moorings unable to put to sea. Kongo was torpedoed and sunk by submarine. Yamato was destroyed on her mission to Okinawa. Prior to Leyte, the IJN battleships had not accomplished anything. They themselves were largely out of the war from the beginning, except for Kongo, Kirishima, Haruna, and Hiei. These four were very involved in escorting the carriers.
In contrast, the Kriegsmarine capital ships were used fairly aggressively at the beginning of the war. The Graf Spee is well known for her cruise, as was Admiral Scheer, Scharnhorst, Gneisenau, and Bismarck. Yes, the KM did lose ships due to its being the inferior force. After the Barents Sea episode, and after Hitler's scrapping order, Gneisenau was scrapped after being bombed extensively during her rebuild into a 15" gunned battlecruiser, Scharnhorst was lost in battle against a British capital ship and her escorts, Tirpitz was sunk while being a "fleet-in-being" while forward-deployed in Norway, Lutzow and Scheer were used against the Soviets in the Baltic.
In other words, there is a myth about the Kriegsmarine capital ships being out of the war that just simply doesn't stand scrutiny. They were aggressive from the beginning of the war, but suffered from being too few ships being led by a landsman who did not understand how to use them. They, too, did not have air superiority, but they fought.
