The Dai-Kaijū (大海獣 Dai-Kaijū, lit. Great Sea Beast) or the Kujira-Gami (鯨神 Whale God) or the Zeuglodon (ゼウグロドン) or the Zeokuronodon (ゼオクロノドン) are either a great kaijū or an ancient whale whose blood is believed to contain the secret to immortality.

Dai-Kaijū's original concept was in the non-Kitarō story Kaijū Raban in 1958 in which Godzilla appeared instead of Dai-Kaijū, it has since become a recurring character in the franchise, appearing in most adaptations.

The actual Dai-Kaijū itself is not as prominent as Kitarō in his Dai-Kaijū form.

Dai-Kaijū is a gigantic, bipedal, and hairy whale with the head resembling that of baleen whales with baleen-like shaped fangs and unproportionally small tail, and gorilla-like limbs. Dai-Kaijū in the 1985 anime possess claws on their fingers.

In the Hakaba no Kitaro, Dai-Kaijū, both the original individual and transformed Yamada were much smaller than in later.

In the Gegege no Kitaro, Dai-Kaijū greatly varies in coloration from brown, ocher, blue, black, and green. While Whale God's actual height is unclear, it can be speculated that total height could be nearly 200 meters tall based on the description in the manga says "six times bigger than whales" and the size comparing to Tokyo Metropolitan Government Building. In the 1985 anime, Dai-Kaijūs possess claws.

Another individual appeared in Kitarō Kunitori Monogatari who visited to watch sumo matches is much smaller than other known individuals.

In the 1996 Anime, there is a contradiction between the skeleton of Zeokuronodon in Baruru Island and the recognition of Zeokuronodon by humanity despite the anatomy of Dai-Kaijū completely differs from the Zeokuronodon's skeleton and briefly seen silhouette of the prehistoric cetacean. Kitarō as the Dai-Kaijū in this version lacks his left eye, corresponding to Kitarō's face.


In Hakaba Kitarō and the GeGeGe no Kitarō series, Dai-Kaijū are a docile race, usually remaining calm. However they will go into a frenzy when provoked.


Hakaba no Kitaro

In the Hakaba no Kitaro, the beast's identity was initially speculated as a Zeuglodon, the ancestor of the modern whale, that became a yōkai indigenous people called Kujiragami (鯨神), but humanity doubted the identification. It has been living in the wetlands of New Guinea for millions of years and especially resided within the Lake Rado, usually appearing at night.[1]


The larger Dai-Kaijū appears in the chapter Dai-Kaijū (story).

The smaller individual appears in the Kitarō Kunitori Monogatari

First Anime

The Dai-Kaijū appears in the fifth and sixth episodes of the first anime adaptation, Dai-Kaijū (Part 1) and Dai-Kaijū (Part 2).

Third Anime

The Dai-Kaijū appears in episodes #67 and #68 of the third anime adaptation, Dai-Kaijū of the Jungle and Dai-Kaijū's Angry Counterattack.

Fourth Anime

The Dai-Kaijū appears in the first movie based on the fourth anime adaptation, GeGeGe no Kitarō: Dai-Kaijū.

Zeokuronodon/Dai-Kaijū is worshiped as a god by Akamata, Chinpo, Yashi-Otoshi, and Kijimuna of Baruru Island. The natural pool inwhich Zeokuronodon's skeleton is situated, is a scared and irrefutable place for the resident Yōkai.

Chinpo stated that it requires such vast amount of spiritual energy from all over the world to resuscitate Zeokuronodon and so they gave up but instead made Kitarō to drink the spiritual water of the pool to transform him into Dai-Kaijū.

Later, Kitarō forgave Akamata and others because a pod of blue whales, descendants of Zeokuronodon, saved and protected him when he was weaken.

Powers and Abilities

While most of the abilities by the original Dai-Kaiju are unclear, Kitarō as Dai-Kaiju performed variety of abilities as he lost all of his original spiritual powers.

Cetacean Physiology

Durability: Kitarō as Dai-Kaijū completely endured a hydrogen-bombing at close range and stand still in the water not to damage Shūichi Yamada and his family hiding within his mouth. Kitarō was heavily damaged as to be extremely exposed to radiation, but he later detoxified all the radiation through urine.

Human Speech: Ichirō Yamada's transformed Dai-Kaijū can talk human speeches hence he could ask help to others.


Comparison of Dai-Kaiju in manga and Daiei's Kujira-Gami.

Dai-Kaijū's baleen plates in the 1996 Anime

  • Kujira-Gami, an alias of Dai-Kaijū by indigenous people of New Guinea, is presumably based on Daiei's Kujira-Gami in 1962. This is further supported by the close resemblances of both characters in specific scenes, and Dai-Kaijū's appearance to have balaenidae-like head with strongly-arched jawline, apparent lack of ventral grooves, and thickest build where Daiei's Kujira-Gami is a North Pacific Right Whale.
  • Dai-Kaijū's "teeth" bends when Kitarō roared, indicating that Dai-Kaijū has baleen plates instead of teeth in the 1996 Anime.
  • Riku Sanjō revealed on an interview for Otona-Media that he was planning to include more of traditional episodes for 2007 anime and he mentioned that Iron Dai-Kaijū was one of those, indicating he was planning to make a Dai-Kaijū episode.[citation needed]
