This article comprehensively introduces all the information you need to know before visiting Koshio Shrine, including its detailed history, enshrined deities, highlights within the grounds, and access methods.
History of Koshio Shrine
Origin and Shrine Records
The founding of Koshio Shrine is described in detail in the shrine’s records. During the reign of Emperor Sujin, when Ōbiko-no-mikoto, one of the Four Generals, was dispatched to the Hokuriku region to pacify the Emishi, it is said that the shrine originated when he enshrined Takemikazuchi-no-kami as Agita-no-ura-no-kami to protect the northern gate.
Later, in the 4th year of Empress Saimei’s reign (658 AD), when Abe no Hirafu visited the Akita region to deal with the Emishi, it is said that he enshrined his ancestor, Ōbiko-no-mikoto, and founded the Koshiō Shrine. This “Koshiō” is believed to have transformed into “Koshiō,” which also refers to Ōbiko-no-mikoto, one of the Four Generals.
Changes in the Shrine Name
The name of Koshiō Shrine has been written in various ways over time. Various spellings of the name, including “越王” (Koshiō), “巨四王” (Koshiō), “胡四王” (Koshiō), “高志王” (Koshiō), “腰王” (Koshiō), and “小四王” (Koshiō), are recorded in historical documents. These are all believed to be kanji representations of the reading “Koshiō,” referring to a king from the Hokuriku region, namely Ōhiko-no-Mikoto.
Relationship with Akita Castle
Koshiō Shrine has a deep connection with Akita Castle. Akita Castle was a fortified settlement established by the imperial court as a governing base for the Tohoku region during the Nara and Heian periods. Koshiō Shrine served as the guardian deity of Akita Castle, attracting worshippers as a god of war. Its location, approximately 1 km south of the Akita Castle ruins, indicates the important role the shrine played in protecting the castle.
Syncretism of Shinto and Buddhism and Shugendō
From the medieval period onward, Koshiō Shrine was strongly influenced by the syncretism of Shinto and Buddhism. It came under the jurisdiction of Shōgoin Shugendō and became associated with the Buddhist belief in the Four Heavenly Kings, leading to its reverence as “Koshiō Daigongen.” Within the temple grounds, Shitennoji Temple was built, giving rise to the place name “Terauchi-ji” (temple town). This district name originates from the fact that it was a temple town integrated with Shitennoji Temple, which was part of the Koshio Shrine complex.
Changes since the Early Modern Period
Records show that in the first year of the Genki era (1570), at the command of Lord Tozawa Hyobu, Magistrate Togashi Saemon Taro Katsuie constructed the shrine of Koshio Daigongen. Togashi family documents state, “Construction of Koshio Daigongen, auspicious day in the fourth month of the first year of the Genki era, by Tozawa Rokuro, also known as Hyobu, Magistrate Togashi Saemon Taro.” The buildings from this period form the foundation of the current shrine.
With the Meiji-era separation of Shinto and Buddhism, Buddhist elements were removed, and the shrine restarted as a purely Shinto shrine. Later, it was ranked as a National Shrine of the lower rank, and remains one of Akita Prefecture’s representative shrines to this day.
Deity Enshrined
Main Deity: Takemikazuchi-no-kami
The main deity enshrined at Koshio Shrine is Takemikazuchi-no-kami. Takemikazuchi-no-kami is known as a god of war and thunder in Japanese mythology, and is also famous as the enshrined deity of Kashima Shrine in Ibaraki Prefecture. According to legend, in the myth of the transfer of the land, he won a test of strength against Takeminakata-no-kami and pacified the land of Izumo.
It is believed that Koshio Shrine enshrined this god of war as the guardian deity of the northern gate to pray for the pacification and protection of the Tohoku region. Takemikazuchi-no-kami’s powerful military and protective abilities served as a spiritual pillar in the imperial court’s administration of Tohoku, centered around Akita Castle.
Enshrined Deity: Ōbiko-no-Mikoto
Ōbiko-no-Mikoto (also written as Ōhiko-no-Mikoto) was a figure dispatched to the Hokuriku region as one of the Four Generals during the reign of Emperor Sujin. He is considered an ancestor of the Abe clan and is credited with contributing to the subjugation of the Emishi people.
During the reign of Empress Saimei, Abe no Hirafu enshrined Ōbiko-no-Mikoto, making Koshiō Shrine a shrine that enshrines both ancestral deities and war gods. The shrine’s name, “Echigo,” also derives from the fact that Ōbiko-no-Mikoto was a general who came from Hokuriku (Echigo).
Relationship with Takaizumi-no-Kami
Near Koshiō Shrine is a spring called “Takashimizu Reizen,” which is worshipped as Takaizumi-no-Kami. According to shrine tradition, there is a legend that the spring gushed forth when Koshiō was enshrined, and it is known as a sacred spring deeply connected to the shrine. This spring has been used by local people since ancient times and has been cherished as sacred water.
Highlights of the Shrine Grounds
