Location: 814 Ose, Itako City, Ibaraki Prefecture
Deity: Takemikazuchi-no-Okami
Former Shrine Rank: Gosha (Village Shrine)
Founding: Daido 1 (806 AD) *Several theories exist
Alternate Name: Formerly known as “Kashima no Omiya”
Ose Shrine, as a shrine that enshrines Takemikazuchi-no-Okami, the same deity as Kashima Jingu Shrine, has long attracted local faith. Located in Ose, Itako City, and surrounded by the Ose Kofun Cluster (ancient burial mounds), it suggests that this area was an important center in ancient times.
History and Origins of Ose Shrine
Circumstances of Founding
There are several theories regarding the founding of Ose Shrine. According to the most widely accepted theory, the shrine originated in 767 AD when it was established by inviting a deity from Kasuga, Shikigami District, Yamato Province (present-day Sakurai City, Nara Prefecture). Later, in 806 AD, during the early Heian period, it is said that the Fujiwara clan relocated the shrine to its current location during their eastern expedition against the eastern barbarians.
Relationship with the Iitomi Clan (Ofu Clan)
According to shrine tradition, the Iitomi clan (Ofu clan: Ta clan) is said to have enshrined the shrine as their tutelary deity when they migrated from Yamato to Hitachi. The place name Oosei is also thought to derive from the sounds “Ofu” and “Ou,” suggesting a deep connection with this clan.
The Oosei Kofun Group, remaining around the shrine grounds, is believed to be the burial ground of this Ofu clan, and is an important historical site that conveys the existence of an ancient powerful family.
The Prestige of “Kashima’s Grand Shrine”
Ose Shrine, formerly known as “Kashima’s Grand Shrine,” held a significant position within the Kashima faith sphere. As a shrine dedicated to Takemikazuchi-no-Okami, it had deep ties to Kashima Jingu Shrine and flourished as a central figure in local faith.
