This woodblock print, designed in late 1855 (Ansei 2), is a prime historical masterpiece of the namazu-e (catfish print) genre by an anonymous Edo-period artist. Following the catastrophic Ansei Great Earthquake that devastated the shogunal capital in November 1855, hundreds of these unauthorized, satirical prints flooded the underground market. They functioned simultaneously as protective amulets, expressions of public anxiety, and witty social commentary on the forced redistribution of wealth. In traditional Japanese mythology, earthquakes were believed to be caused by a colossal subterranean catfish thrashing beneath the earth whenever the deity Kashima let down his guard.
