The creature lives under the islands of Japan and is guarded by the god Takemikazuchi enshrined at Kashima, who restrains the catfish with a stone. When the Kashima-god lets his guard fall, Namazu thrashes about, causing violent earthquakes.
The association of the namazu with earthquake seems to have first occurred in the area around Lake Biwa, around the 16th century. The namazu had been depicted in the Ōtsu-e ("pictures from the city of Otsu") which were manufactured in that area.[a]
This earthquake-causing creature became associated with the deity and "foundation stone" in Kashima, Ibaraki. According to myth, the god Takemikazuchi enshrined at Kashima restrains the catfish underneath a stone (kaname-ishi, perhaps "foundation stone" but maybe more aptly "cap stone"). When the Kashima-god lets his guard fall, Namazu thrashes about, causing violent earthquakes.
It is believed by some[who?] that the origin of the story is the notion that catfish can sense the small tremors that happen before many earthquakes, and are more active at such times. Supposedly, the sudden activity was observed in ancient times and people believed the quakes to be the result of a giant catfish.
Namazu-e ("catfish prints") were a known item in the 19th century, and these broadsides were printed in great quantity following an earthquake near Edo (modern day Tokyo) in 1855 (one of the Ansei great earthquakes).
These namazu-e woodblock-prints encompass a large variety of scenes, typically depicting the god subduing the earthquake-causing catfish under a sword or the kanameishi stone. The creature is sometimes referred to as just the "earthquake fish" (jishin-no-uo), and the despite the text calling it a catfish, the illustration may be that of a dragon-serpent.
Even though the Namazu was held responsible for the disaster,[b] it was also ironically hailed as a yonaoshi daimyōjin (god of "world rectification"), that is to say, a sort of an "avenger of social injustice" which expressed the public's political sentiment at the time. The rich had hoarded their wealth but these were largely disgorged due to the earthquake, and redistributed to the world at large: such is the symbolism of the large gold coins (koban, etc.) scattered by the earthquake depicted in the pictures. A large amount of money went into the rebuilding effort, and the job opportunities resulted in a redistribution of wealth.
One picture is printed with a jingle with the refrain "yo-naoshi, yo-naoshi, tate-naoshi" (literally "world-fixing, world-fixing, re-building", which explicitly makes this connection.
- Catfish are depicted on pictures of emergency earthquake preparedness activities in Japan. For example, the Earthquake Early Warning (EEW) logo by the Japan Meteorological Agency utilizes pictures of the catfish on devices capable of issuing an early warning. The popular earthquake early warning mobile application Yurekuru Call also has a catfish as their icon.
- Namazu is also the name of a song on Danish singer Oh Land's first studio album Fauna, which features a large catfish on the album cover.
- In the Japanese version of Secret of Mana, the Earth Slide (Earthquake in the Japanese version) spell is a catfish icon in the ring menu.
- In The Legend of Zelda: A Link to the Past, a catfish gives Link the Quake Medallion.
- A giant catfish mimicking Namazu's habits appears as a boss figure in the video game Lufia II.
- The Pokémon Whiscash, named "Namazun" in Japan, resembles a catfish and has "earthquake" as its signature move. An episode of the Pokémon anime featuring Whiscash was scheduled to air on November 4, 2004, but was skipped over after the 2004 Chūetsu earthquake.
- The Namazu was featured in the episode of River Monsters, "Cold-Blooded Horror".
- Namazu appears in a crossover comic book featuring Stan Sakai's Usagi Yojimbo and IDW's Teenage Mutant Ninja Turtles.
- The Namazu are a Beast Tribe race that resembles bipedal catfish in Final Fantasy XIV: A Realm Reborn.
- In S1:E7 of Dragon Ball GT, the character Zoonama appears as a giant catfish that wiggles his whiskers when detecting earthquakes, and repeats the word "Namazu" in his speech.
