The Katsuragi, an Unryu class aircraft carrier, was laid down at the Kure Navy Yard on December 8, 1942 and was launched a little more than a year later, on January 19, 1944. It wasn't until October 15, 1944 however that she was completely finished, but despite being completed she was never deployed. She was damaged by air strikes on Kure late in the war and never participated in combat actions. After the war she was used as a repatriation ship until 1947, when she was scrapped in Osaka.

The Katsuragi, as a member of the Unryu class of aircraft carriers, the final class of fleet carriers built by the Imperial Japanese Navy, was intended to be used in attacks against US convoys, not in fleet actions. She was to serve with large screen of cruisers and destroyers and, with that in mind, was fitted with a power plant similar that that used cruisers and destroyers. The Katsuragi was one of only two other Unryu class carriers to be completed, though all were sunk close to port without ever seeing combat.
