Jishin Miyōsaku Getokusan ‎

Considered a yōkai, Namazu is a mythical giant catfish who causes earthquakes and lives ‎buried in the mud. It lives under the islands of Japan. When Namazu is awakened, he ‎thrashes about, causing earthquakes. According to legend, the kami Takemikazuchi, ‎enshrined at Kashima, is the only one capable of restraining the catfish, thanks to his sword. ‎But sometimes this kami falls asleep and lets his guard down. Then Namazu awakens and ‎starts moving, causing new earthquakes. ‎
The Ansei Era (1854-1860) earthquake that occurred in the city of Edo in the 10th month of ‎‎1855 led to the production of several prints called namazue (catfish prints), so named due to ‎the popular belief that earthquakes were caused by the Namazu yōkai, moving around ‎beneath the earth. In general, the catfish is depicted as a long-bodied fish with no scales, a ‎flattened head, and a large mouth with sharp teeth, with two pairs of barbels protruding from ‎its jaws. Since Takemikazuchi was believed to be the only one capable of restraining the ‎creature, he was also associated with the Ansei earthquake in several prints. In this image, on ‎a dais, Takemikazuchi, kami of the Kashima Shinto shrine, points accusingly to an image of ‎Namazu, the source of the earthquakes, in front of the people who look on with angry and ‎surprised expressions. The word jishin in the title means "earthquake." Likely published in ‎‎1856, the Ansei kembun shi (Record of Personal Observations on the Ansei Era) states that ‎after the earthquake, rougly 320 prints, pamphlets, and books about the event were in ‎circulation. These were swiftly purchased on the streets by the general population. These ‎publications are rarely signed by an artist or publisher, and while they do not bear a dated ‎inscription, it may be assumed that the majority appeared following the earthquake.‎
