The "doorless shed" here mentioned, is a "parturition house."[85] It was the custom in ancient Japan for women, when the time drew near for their delivery, to retire to a shed specially constructed to receive them, so that contamination to the dwelling-house might be avoided. This was still the practice in the island of Hachijō in 1878, and even in Japan no longer than a century ago.

The burning of the parturition house represents the ordeal by fire, which, with the ordeal by boiling water or mud, is well known in Japan.

Ho no Susori and Hohodemi.--The story concerns itself no further with the youngest of these three children. Of the others, the elder, named Ho no Susori, became a fisherman, and the younger, Hohodemi, a hunter.

Ho no Susori once proposed to his brother to exchange their respective callings. Hohodemi accordingly gave over to his elder brother his bow and arrows and received a fishhook in return. But neither of them profited by the exchange, so Ho no Susori gave back to his brother the bow and arrows and demanded from him the fish-hook.

Hohodemi, however, had in the meantime lost it in the sea. He took his sword and forged from it a number of new fish-hooks which he piled up in a winnowing tray and offered to his brother by way of compensation. But the latter would have none but his own, and demanded it so vehemently of Hohodemi as to grieve him bitterly. Hohodemi went down to the sea-shore and stood there lamenting, when there appeared to him the Old Man of the Sea, by whose advice he descended into the sea depths to the abode of the God of the Sea, a stately palace with lofty towers and battlements. Before the gate there was a well, and over the well grew a thick-branching cassia tree, into which Hohodemi climbed. The Sea-God's daughter Toyo-tama-hime (rich jewel maiden) then came out from the palace to draw water. She saw Hohodemi's face reflected in the well, and returning within reported to her father that she had seen a beautiful youth in the tree which grew by the well. Hohodemi was courteously received by the Sea-God, Toyo-tama-hiko (rich jewel prince) who when he heard his errand, summoned before him all the fishes of the sea and made inquiry of them for the lost fish hook, which was eventually discovered in the mouth of the Tai. Toyo-tama-hiko delivered it to Hohodemi, telling him when he gave it back to his brother to say "a hook of poverty, a hook of ruin, a hook of downfall," to spit twice and to hand it over with averted face.

Hohodemi married the Sea-God's daughter Toyo-tama-hime and remained with her for three years. He then became home-sick and returned to the upper world. On the beach where he came to land, he built for his wife, who was soon to follow, a parturition house which he thatched with cormorant's feathers. The roofing was still unfinished when she arrived, riding on a great tortoise. She went straight into the hut, begging her husband not to look at her. But Hohodemi's curiosity was too strong for him. He peeped in, and behold! his wife had become changed into a wani (sea-monster or dragon), eight fathoms long. Deeply indignant at the disgrace put upon her, Toyo-tama-hime abandoned her new-born child to the care of her sister, and barring behind her the sea-path in such a way that from that day to this all communication between the realms of land and sea has been cut off, returned hastily to her father's palace.

The child thus born was the father of Jimmu Tenno, the first human sovereign of Japan.

Hohodemi's troubles with his elder brother were renewed on his arrival home. He was obliged to use against him two talismans given him by his father-in-law. One of these had the virtue of making the tide flow and submerge Ho no Susori and thus compel him to sue for mercy (another account says that Hohodemi whistled and thereby raised the wind and the sea). Then by a second talisman the tide was made to recede and Ho no Susori's life was spared. He yielded complete submission to his younger brother, and promised that he and his descendants to all generations would serve Hohodemi and his successors as mimes and bondservants. The Nihongi adds that in that day it was still customary for the Hayato (or Imperial guards), who were descended from Ho no Susori, to perform a mimic dance before the Mikados, the descendants and successors of Hohodemi, in which the drowning struggles of their ancestor were represented.

The castle-gate and the tree before it, at the bottom of which is a well which serves as a mirror, form a combination not unknown to European folk-lore. We may also note the partiality evinced for the younger of two brothers, the virtue of spitting and of set forms of speech to bring good or ill luck, and of whistling to raise the wind.

There are several features in this story which betray a recent origin and foreign influences. A comparatively advanced civilization is indicated by the sword and fish-hooks forged of iron (the Homeric fish-hook was of horn). The institution of the Hayato as Imperial Guards belongs to a period not very long antecedent to the date of the Nihongi and Kojiki. The palace of the sea-depths and its Dragon-king are of Chinese, and therefore of recent, origin. The comparatively modern character of this important link in the genealogy which traces back the descent of the Mikados to the Sun-Goddess confirms the view that the so-called ancestor-worship of the ancient Japanese is a later accretion upon what was in its origin a worship of the powers of Nature.
