Kwaidan: Stories and Studies of Strange Things

More than seven hundred years ago, at Dan-no-ura, in the Straits of Shimonoséki, was fought the last battle of the long contest between the Heiké, or Taira clan, and the Genji, or Minamoto clan. There the Heiké perished utterly, with their women and children, and their infant emperor likewise—now remembered as Antoku Tennō. And that sea and shore have been haunted for seven hundred years... Elsewhere I told you about the strange crabs found there, called Heiké crabs, which have human faces on their backs, and are said to be the spirits of the Heiké warriors. But there are many strange things to be seen and heard along that coast. On dark nights thousands of ghostly fires hover about the beach, or flit above the waves,—pale lights which the fishermen call Oni-bi, or demon-fires; and, whenever the winds are up, a sound of great shouting comes from that sea, like a clamor of battle.

In former years the Heiké were much more restless than they now are. They would rise about ships passing in the night, and try to sink them; and at all times they would watch for swimmers, to pull them down. It was in order to appease those dead that the Buddhist temple, Amidaji, was built at Akamagaséki. A cemetery also was made close by, near the beach; and within it were set up monuments inscribed with the names of the drowned emperor and of his great vassals; and Buddhist services were regularly performed there, on behalf of the spirits of them. After the temple had been built, and the tombs erected, the Heiké gave less trouble than before; but they continued to do queer things at intervals,—proving that they had not found the perfect peace.
