It may look like a small inconspicious village shrine, but Serida Shrine has some vintage. It is listed in the Izumo Fudoki, so has existed since before the 7th Century, and is also listed in the Engi Shiki, therefore it received offerings from the imperial government in the Heian period.
The main kami enshrined here is listed as Kanayamabiko, who came into existence from the vomit of Izanami as she was dying after giving birth to fire. However, according to an excellent website on the history of iron in Japan at Hitachi Metals, it was probably called Kanayago before the Meiji Period.
Kanayago is a very popular kami among iron and metal workers and the head kanayago shrine is a little east of here. The Chugoku region and especially this part of Izumo was a main center for iron production in ancient times, and there are many Kanayago shrines.
Also enshrined here is Izanami and Kotosakano and Hayatamano, the latter two being the kami that came into existence at the time of Izanagi's oath of divorce from Izanami. Curiously they are linked with Izanami here rather than Izanagi.
This area is between the entrance to Yomi where Izanagi visited Izanami, and Izamani's tomb on top of Mt. Hiba.
