Yamaton (ヤマトン Yamaton) was a battleship inspired Kaiju from Daiji Kazumine's manga adaptation of Ultraman.

Subtitle: Battleship Monster (軍艦怪獣 Gunkan Kaijū)



In the years following World War II, the wreckage of the once-mighty IJN Yamato rested on the sea floor of the South Pacific. Small aquatic creatures (including barnacles and oysters) somehow merged with the wreck, creating Yamaton. Soon it made its way to Tokunoshima and attacked the docks. Tanks and fighter jets tried to attack it but were magnetised to the monster. As Ultraman appeared, he tried to attack but being a former battleship, Yamaton's body is already durable to the hero's might, even the Spacium Beam had no effect. Soon Ultraman was magnetised and was about to be devoured but instead of struggling to escape, he willingly got eaten, then destroyed Yamaton from the inside out, allowing the wreckage to rest in peace once again.


  • Yamaton originally was intended to appear in the Ultraman show, but due to time constraints, the beast wasn't used. Concept art of Yamaton's suit exist and eventually, a Yamato-themed ship was created in the form of Iron Rocks in Ultraseven.
  • It is known that the original battleship Yamato had her width 39 m and full length of 263 m so it can be safely assumed that Yamaton is the same size as the namesake battleship.
  • Despite being very obscure, even by Ultra Kaiju standards, Yamaton, and fellow manga kaiju, Tangilar, received toy versions of themselves created by Marusan.
  • Yamaton's name and likeness is a reference to the Battle Ship, Yamato.
  • The idea of an Ultra Warrior fighting a living battleship was not a pass over concept, as Iron Rocks and Barrack Ship appeared later in the series.
  • In the manga, since Alien Baltan were revealed to be the main antagonists, it is possible that Yamaton's creation was partly their bidding, due to said alien race had released microscopic lifeforms around the Earth that used to create monsters fought by Ultraman and SSSP.
