Reader "Swinebread" left comments regarding Kaname-ishi, the stone which the Kashima diety uses to control the catfish that causes earthquakes. The catfish monster is called Namazu. A couple of years ago, in Saitama, Swinebread saw a showing of old woodblock prints about the catfish, some like the one in Kashima Jingu are shown being held down, others are subdued with sake, women, and song. Some of the prints are pretty humorous. Click on either image to go the site and see all of the prints. The prints are called "Namazu-e". Thanks for link Swinebread.
On November 11, 1855, an earthquake of magnitude 6.9 -The Great Ansei Edo Earthquake - detroyed Edo (now Tokyo). Woodblock prints about the quake and about the catfish were printed in large numbers. Coming soon after the visits of Commodore Perry in 1853 and 1854 which ended Japan's isolation, as well as other earthquakes, people in Edo saw the earthquake in political and philosophical terms as a yonaoshi - "world rectification". The earthquake was meant to shake up a sleeping nation and had political implications which are the topic of some of these prints.
