Yesterday we had the third Shinto texts course, this time looking at the Kogoshui and the archaeological background. The Kogoshui may not be familiar even to people who know a bit about Shinto, so I’ll say a bit about it first, as the lecturer, Professor Sasao, did.
The Kogoshui was written in 807 by Inbe Hironari, who was eighty years old at the time, and, in the preface, famously complains that young people today (in 807) don’t pay attention to the wisdom of the past. The work is polemical, and has its origins in a dispute over family rights at the imperial court. In the Yamato court, three families were responsible for the rituals to serve the kami: the Inbe, the Sarume, and the Nakatomi. Each family claimed descent from one of the kami responsible for the ritual that lured Amaterasu out of the cave in heaven: the Inbe from Futodama, the Nakatomi from Amenokoyane, and the Sarume from Amenouzume. (It seems quite likely that those three kami play important roles in the legend because they were the ancestral kami of the ritualist families.) However, a member of the Nakatomi, Nakatomi Kamatari, played an important role in the coup in which Emperor Tenji seized power in the mid seventh century, and was granted the new name “Fujiwara”. The Fujiwara became extremely influential, eclipsing the emperor in actual power, and so their relatives, the Nakatomi, became more dominant in ritual. In 806, things came to head in a debate over which family should supply the emissaries who carried imperial offerings to shrines around Japan. The emperor initially solved it by saying that both families should supply emissaries, but asked the Inbe for an account of their traditional rights. That account it is Kogoshui.
It is not very long, but it covers quite a bit of ground. The lineage and origins of the Inbe are, of course, central, and the other kami led by Futodama also play an important role. There is a detailed discussion of the legend of Amaterasu in the cave, and of the roles of the kami associated with Futodama in providing the offerings for the kami. In addition, the history of the Inbe is brought down to the end of the eighth century. Throughout the whole work, there are also criticisms of the Nakatomi, and the Kogoshui contains a number of legends that are not found in the Kojiki or Nihonshoki. All of these factors make it a very valuable resource, telling the early legends of Shinto from a slightly different perspective from the official histories.
As Professor Sasao said, the main point of the work was to criticise the Nakatomi, so if we don’t say something about them, it’s a bit rude to the author. Essentially, Hironari complained that the Nakatomi were monopolising the ritual roles. He said that the other two families had been excluded from the chief priest’s position at the Grand Shrines of Ise, and that all the offerings from the regional shrines to the imperial court were being funnelled to the Nakatomi. He also said that, in forming the system of shrines venerated by the court, any shrine connected to the Nakatomi, no matter how small, was being listed, while shrines with no connection to them, no matter how big, were being ignored. It’s now very difficult to confirm this, because there is no independent evidence for the size of shrines that were ignored by the court; to the best of my knowledge there are no contemporary shrines that are known to have been important in the eighth century but to have been ignored by the court.
Professor Sasao picked up three points to illustrate the light that archaeology and the text can shed on each other.
The first concerns the imperial store rooms. According to the Kogoshui, Emperor Jinmu put the Inbe in charge of the imperial storehouse, called the “imi no kura”. In later years, when tribute started to come in from the Korean peninsular, a second storehouse, called the “uchi no kura” was established, and its administration entrusted to people who had come from the Korean peninsular themselves. Somewhat later, in the fifth century, a third storehouse, the “ohkura”, was established, and put under the administration of another family of immigrants (the Hata, who founded the Inari cult). The imi no kura housed ritual items and treasures of the kami, while the others housed imperial property.
Archaeology backs up the substance of this account, although it greatly compresses the timescale. The remains of storehouses have been excavated near ritual sites from various places in Japan (Chiba, Shizuoka, and Nara prefectures), dating from the fifth century. This suggests that it was not at all uncommon for storehouses to be associated with rituals. In addition, the Grand Shrines of Ise include storehouses, rebuilt every twenty years, and the designs are very, very similar to those reconstructed from the archaeological remains. Similarly, in the same period, remains of large storehouses have been found associated with imperial palaces.
In a later section, Hironari claims that an Inbe was the head of the bureau of divinities in the mid seventh century, and that the practice of using turtle shells to divine the health of the emperor was introduced at that time. The official histories claim that a Nakatomi held the post, but the Kogoshui appears to preserve the seventh century name for the post, and thus may be more accurate. In any case, archaeology shows that, in the mid seventh century, the court started building imperial palaces on a far larger scale than before. Thus, this seems to have been an important point in the introduction of the classical Ritsuryo system, and thus a reasonable time for a divinatory ritual to start. In addition, the first evidence of turtle shell divination in Japan is from the late sixth century, and after a peak in the seventh, it declines sharply in the eighth. The Nihonshoki records the import of books on many subjects, including divination, from the Korean peninsular in the sixth century, so this form of divination may have been introduced to Japan at that point. In that case, the most advanced form of divination was used to discover the emperor’s condition.
Finally, the Kogoshui attributes the development of the Boso peninsular in modern Chiba prefecture to a kami associated with Futodama, Amenotomi. It records the foundation of Awa Shrine in the south of the peninsular, and this shrine, along with Kashima and Katori shrines, had dedicated villages to support it, indicating its importance. Archaeology in the shrine precincts turned up items from the fifth century, suggesting that rituals on the site may go back that far. An earlier ritual site, from the fourth to fifth century, was found to the south of the shrine, at the extreme of the peninsular, so the rituals may have moved in the fifth century.
Once again, the evidence suggests that a lot of recognisably Shinto elements, and worship at contemporary shrine sites, can be traced back to the fifth century, reinforcing that as a strong candidate for the date when Shinto began. In addition, the reminder that there are other legends not found in the Kojiki or Nihonshoki once more brings the diversity of Shinto to the fore. This course is continuing to be extremely interesting.
