*Hanzaki Daimyojin* is the spirit of a monstrous Japanese giant salamander (*hanzaki*) passed down in Mukai-Yubara Village (present-day Yubara Onsen, Maniwa City, Okayama Prefecture) on the upper reaches of the Asahi River in Mimasaka Province. "Hanzaki" is an old name for the Japanese giant salamander in the Chugoku Mountains, said to derive from the belief that it would continue to live even if its body was torn in half (*hanbun ni saku*). It is told that a giant *hanzaki* reaching three *jo* and six *shaku* (about 10 meters) in length lived in a deep pool called Ryuzu no Fuchi, using its tail to knock people and horses into the depths to devour them [1]. After it was slain, it laid a curse, and to appease it, a shrine was built where it was enshrined as "Hanzaki Daimyojin" (Great Deity Hanzaki). This is a classic example of a monster transforming into a god, and it lives on today in the Yubara Onsen area through the annual "Hanzaki Festival" held on August 8th [2].
Folklore & Legends
The *Sakuyo-shi* (History of Mimasaka), a local topography from the early Edo period (1691), records this legend as an event that occurred about a century earlier [3]. Around the Bunroku era (circa 1593), a young man from Mukai-Yubara Village named Mitsui Hikoshiro volunteered to slay the giant *hanzaki* that was terrorizing the village. Hikoshiro tied a rope around his waist, had the villagers hold the other end, and intentionally let the *hanzaki* swallow him. Once inside, he sliced open its belly from the inside with his short sword and was pulled out to safety by the villagers. The giant *hanzaki* hauled ashore was a behemoth measuring some 10 meters long and over an arm's span in girth [3].
However, after the slaying, the sound of weeping echoed through Hikoshiro's house every night, and his family members fell ill one after another until the Mitsui family finally died out. As misfortunes continued to strike the village as well, the people feared the *hanzaki*'s curse. They built a shrine on the banks of Ryuzu no Fuchi, enshrining it as "Hanzaki Daimyojin," and comforted its spirit with sutra recitations and prayers [1]. This act of appeasement is said to be the origin of the "Hanzaki Festival" that continues to this day on August 8th, a unique Okayama festival where giant *hanzaki* floats and lion dances parade through the hot spring town [2]. The narrative of a slain beast transforming from an avenging curse-spirit into a guardian deity of the land is a precious example of typical *Goryo* (vengeful spirit) worship transmitted to the valleys of the Chugoku Mountains.
It is not a half-human, half-yokai, but rather a "half-god, half-beast" monster whose core is a highly realistic slaying tale recorded in the Mimasaka topography *Sakuyo-shi*. The biological Japanese giant salamander is an actual Special Natural Monument inhabiting the Asahi River system; its bizarre appearance and longevity sparked the imaginative belief that it was immortal and "wouldn't die even if torn in half." Its gigantified form was feared as the master of Ryuzu no Fuchi. The causal chain wherein the slain creature's curse wiped out the Mitsui family speaks of the beast's grudge destroying even the victorious slayer, ultimately only quieted by enshrinement. It possesses a rare structure combining a monster-slaying tale, a curse tale, a deification tale, and a festival origin. At the Hanzaki Center in Yubara Onsen, live giant salamanders are still protected and exhibited today, making it a land where legend and reality exist side-by-side.

Vulnerable to being sliced open from the inside with a blade, and loses its true power if removed from its pool. Its raging power subsides when it accepts appeasement through sutra chanting, prayers, and enshrinement.
Habitat
Deep pools such as Ryuzu no Fuchi on the upper Asahi River (present-day Yubara Onsen, Maniwa City, Okayama Prefecture).
