Rock border - Iwasaka

Japanese: 磐境 - いわさか
Rock border - Iwasaka

A facility for worshiping divine spirits. The only article that mentions "Amatsuhimorogi and Amatsuiwasakuya" is in the first book of the Tenson Korin Chapter in Volume 2 of the "Nihon Shoki," and the same text can be found in the "Kogoshuui." There are a few theories about its actual form, but it is assumed to have been a small stone enclosure that was built from time to time for worship. Archaeologically, it is thought to be a 1-2 meter diameter area made of natural stones and used as a ritual site, as seen at the Sakatayama Site in Shirahama-cho, Wakayama Prefecture, and the Okinoshima No. 22 Site in Munakata-gun, Fukuoka Prefecture, and ritual artifacts have been found inside. There are circular and square stone enclosures, but the difference in their usage is unclear. There was once a strong theory that Kogoishi was the iwasakuya, but it is now clear that it was a mountain castle.

Japanese:

神霊祭祀(さいし)の施設。『日本書紀』巻2、天孫降臨章の一書に「天津神籬(あまつひもろぎ)及天津磐境云々」とあるのが唯一の記事で、『古語拾遺(こごしゅうい)』にも同文がみられる。その実態については二、三の説があるが、祀(まつ)りのため随時設けた小規模な石囲いの施設と推定される。考古学上、和歌山県白浜町坂田山遺跡、福岡県宗像(むなかた)郡沖ノ島22号遺跡などにみられる、自然石で径1~2メートル程度の区画をつくって祭場にしたものがこれにあたると思われ、その内部からは祭祀遺物が発見されている。石囲い施設には円形と方形とがみられるが、用法上の区別は明らかでない。かつて神籠石(こうごいし)を磐境とする説も有力であったが、現在は山城であることが明確になった。
