Tonight’s yokai is one that has been covered by famous yokai artists like Toriyama Sekien. Here in Mimibukuro it is referred to as Ikuji or ikuji (it isn’t clear if this is a singular monster or a species of creatures), while in other places it is known as ayakashi or ikuchi.
Negishi also gives us a fun folk etymology, linking the word “ikujinashi” (written “ikujinaki” here to reflect the archaic way it is written in Mimibukuro) to this yokai. Ikujinashi means a coward/weakling/loser/good-for-nothing person. Although it’s not clear how that word would relate to this creature…
The Thing in the Sea Called Ikuji
In the Seto Inland Sea and the waters off of Kyūshū there is a creature called an ikuji that sometimes climbs across the bows of ships. Its body resembles that of an eel, and its length is longer than can be measured. Once it climbs onto a ship’s bow it can supposedly take two, sometimes three days to slither all the way across. How many tens or hundreds of jō long it is, I can not even guess. The term “ikujinaki” (“good-for-nothing”) probably originates from this.
According to another person’s account, “smaller versions of these ikuji inhabit the coasts off of Izu and Hachijō. These creatures look like eels in the shape of rings, with no eyes or mouth. Therefore, the kind that is said to climb across the bows of ships is not one that has grown very long, but is merely looping around the bow in the shape of a ring.”
I don’t know which version is true, but they don’t particularly cause any harm to the ships.
