According to legend, the origins of Munakata lie in
Japanese mythology. Per the
Kojiki and
Nihon Shoki, When
Amaterasu Omikami and
Susanoo no Mikoto made a vow, Amaterasu bit into pieces Susanoo's sword, and the three Munakata goddesses were born from the pieces that blew out. The goddesses, following Amaterasu's divine command, descended to the
Tsukushi Munakata Islands in the
Genkai Sea to watch over and help the imperial grandson
Ninigi no Mikoto, and began to rule this land, which is said to be the origin of Munakata Taisha Shrine. Regarding the sacred objects and shrines of the three Munakata shrines, the
Chikuzen Fudoki states, 'When Munakata-no-Okami descended from the heavens to Mount Saimon, he presented the blue jewel-placed in Okutsu Shrine, the eight-foot purple jewel-placed in Nakatsu Shrine, and the Yatagara-no-kagami-in Henotsu Shrine. Per these accounts,
Empress Jingu prayed here for the safety of her voyage during her
conquest of the
Three Kingdoms of Korea, and this miraculous power led to the custom of sending offering messengers to Munakata on various occasions. The Yamato court held the shrine in high esteem, and whenever the capital was relocated in ancient times, a branch shrine was enshrined in the Kashikodokoro (a sacred place) within the palace. This anecdote also provides insight into how the shrine came to be worshipped as the guardian deity of safe navigation. When the
Ritsuryo system was established, the entire Munakata district was granted as a sacred territory, and the local powerful Munakata clan served the shrine as priest and also oversaw the secular administration of the district. According to a stone monument recording the history of the Munakata clan, two generations of Munakata clan leaders married the daughters of Chinese merchants. Furthermore, Munakata Tokuyoshi married his daughter, Amago no Musume, into the harem of
Emperor Tenmu. Their first son, Prince Takaichi, born in 654, assisted his father in the
Jinshin War and achieved great success, later becoming
Grand Minister of State.
Prince Nagaya was Takaichi's son and also the ancestor of the Takashina clan. From the
Kamakura period onwards, the Munakata clan, transformed into
samurai and grew into powerful local lords. However, during the
Sengoku period, they were mobilized in wars between neighboring
daimyō such as the
Ōuchi,
Ōtomo, and
Shōni clans, and Munakata Taisha became the target of military attacks, frequently suffering from arson and destruction, and the Munakata clan itself declined. However, each time, the shrine was rebuilt thanks to the support of the Imperial Court and samurai. The current Hetsumiya
Honden, with its beautiful large thatched roof, was rebuilt in 1578 by Grand Priest Munakata Ujisada, while the Hetsumiya
Heiden was rebuilt in 1590 by
Kobayakawa Takakage, lord of
Chikuzen Province. Both the Honden and Heiden of Hetsumiya are designated as
Important Cultural Properties of Japan. The rituals previously performed by the Munakata clan were later passed on to the Kusakari clan (Kusakari Shigetsugu). During the
Edo period, there are numerous accounts of the construction and repair of shrine buildings and donations of land by the
Kuroda clan,
daimyō of
Fukuoka Domain. Subsequently, during the
anti-Buddhist movement from the end of the Edo period to the
Meiji era, Byobuyama Chinkoku-ji, the
jingū-ji, was separated from the shrine In 1871 (Meiji 4), under the
Modern system of ranked Shinto Shrines, as "Munakata Jinja" the shrine was ranked as a National shrine, 2nd class. On April 22 of the following year, it was elevated to an Imperial shrine, 2nd class. On July 11, 1901, it was promoted to the highest rank of . After
World War II, the temple grounds, which had fallen into disrepair, were renovated thanks to a donation from
Sazō Idemitsu, businessman and founder of the petroleum company
Idemitsu Kosan, who had been born in Akama (Akama district, Munakata City) ==Cultural Properties==
