The Ibuki Trees of Hachimanjinja Shrine: Eight Centuries of Living History in Uwajima
Tucked away in a quiet residential district of Uwajima City on the southwestern coast of Shikoku, two extraordinary trees rise above the worship hall of a small countryside shrine. These are the Ibuki Trees of Hachimanjinja Shrine — a pair of Chinese junipers (Juniperus chinensis) said to be more than 800 years old, designated as a National Natural Monument in 1943. They are far more than venerable plants. They are the reason the shrine bears its name, the reason the surrounding town is called Ibuki-cho, and according to local legend, they were planted by a retainer of one of Japan's most celebrated samurai heroes.
For travellers seeking out the quieter, more contemplative corners of Japan — places where centuries-old stories continue to live and breathe — these two living giants offer a deeply rewarding pilgrimage.
What Are the Ibuki Trees?
The Ibuki, also known in Japanese as Byakushin or Shimpaku, is an evergreen coniferous tree of the cypress family (Cupressaceae). It is famous for its distinctively twisted trunk, its resistance to coastal salt winds, and its extreme longevity. The species naturally inhabits the Pacific coast of Honshu, Shikoku, Kyushu, Okinawa, the Korean Peninsula, and parts of China, often clinging to rocky outcrops near the sea.
The two Ibuki trees of Hachimanjinja Shrine — both female specimens — stand directly in front of the worship hall (haiden), one on either side. According to records compiled by Uwajima City, the trunk of the tree on the left has a circumference of approximately 4.2 metres, while the one on the right measures roughly 4.8 metres. Both reach a height of about 20 metres. Although typhoons over the centuries have stripped away branches and left visible scars, the trees remain vigorous, putting forth dense green foliage year after year.
Why Were They Designated a National Natural Monument?
The Ibuki Trees of Hachimanjinja Shrine were designated a National Natural Monument on 19 February 1943, recognising them as outstanding examples of giant Ibuki trees. Several qualities make them exceptional.
First, their age. With trunks that have been growing for more than eight centuries, these trees predate the formation of the Tokugawa shogunate and have witnessed every major chapter of Japanese history since the late Heian and early Kamakura periods.
Second, their scale. While Ibuki typically grow to between 15 and 20 metres, the size and girth of these two specimens place them among the largest of their kind in Japan. Within Ehime Prefecture, four locations are home to nationally designated Ibuki trees, and across the entire country there are only twelve such designations — a small and select company.
Third, their cultural and historical role. The trees are inseparable from the identity of the shrine, the neighbourhood, and the local community. The shrine is named after the trees, and the surrounding town in turn takes its name from the shrine. Few natural monuments in Japan are so deeply woven into the very geography and language of the place that hosts them.
The Legend of Minamoto no Yoshitsune
The most captivating story attached to these trees concerns the legendary samurai Minamoto no Yoshitsune (1159–1189). According to tradition, when Yoshitsune was appointed Governor of Iyo Province in 1185, he ordered the rebuilding of Hachimanjinja Shrine and instructed his trusted retainer, Suzuki Saburo Shigeie, to plant the two junipers as a sacred offering.
If the legend is accurate, the trees would now be approaching their 840th year. Whether this exact attribution can be historically verified or not, the connection to Yoshitsune — one of the most beloved tragic heroes of Japanese culture, immortalised in Noh theatre, kabuki and countless folk tales — gives the trees an aura of romance and significance that extends far beyond botany.
Inside the shrine, you will also find an ema (votive plaque) depicting "Ushiwakamaru and Benkei on Gojo Bridge," a famous scene from Yoshitsune's youth, which is designated as a Tangible Cultural Property by Uwajima City — another quiet nod to the shrine's enduring association with this legendary warrior.
Highlights and Things to See
The Twin Trunks Before the Worship Hall
Approach through the torii gate and you will see them immediately: two enormous, deeply furrowed trunks rising on either side of the path, spreading their dark green canopies over the worship hall. Standing beneath them and looking up at branches that have weathered eight centuries of typhoons is genuinely moving. The trunks twist in characteristic Ibuki fashion, and the bark is mottled with moss and lichens.
The Shrine Itself
According to shrine records, Ibuki Hachimanjinja was founded in the year 712 (Wadō 5), having been spiritually transferred from the great Usa Hachimangu in Oita Prefecture, Kyushu. Its enshrined deities are Emperor Ōjin, Empress Jingū, and the three Munakata goddesses. The shrine has long been considered a guardian of safe childbirth, business prosperity, and protection from misfortune. From 1704 onwards it served as the chief tutelary shrine of Uwa-gun.
Connections to the Daimyo of Uwajima
The shrine is tied to two of the great names of Edo-period western Japan. Tōdō Takatora, the famous castle-builder and lord of the area in the early 1600s, restored the shrine and is said to have personally dedicated a written inscription. Later, Date Hidemune, the first lord of Uwajima Domain, re-roofed the main hall, erected torii gates, and donated a tachi (long sword) and a naginata. Their patronage transformed the shrine into a place of regional importance.
Iyo Kagura and the Autumn Festival
The shrine is also a key transmission site for Iyo Kagura, a sacred dance tradition designated as an Important Intangible Folk Cultural Property of Japan. A kagura performance manual dating from 1738 is preserved here. The shrine's annual festival on 16 October features traditional southern-Ehime elements such as the ushi-oni (a fearsome bull-demon mythical creature carried through the streets), yotsudaiko drum floats, and the procession of mikoshi portable shrines.
Visitor Information
Hachimanjinja Shrine is located in Ibuki-cho, on the northern edge of Uwajima City. The grounds are open at all times and there is no admission fee. Visitors are welcome to walk freely around the shrine precincts and view the Ibuki trees from beneath, although out of respect for their sacred status and fragile root systems, please do not touch the trunks or step over the rope barriers if any are present.
The most convenient access is by JR train: alight at Kita-Uwajima Station on the JR Yosan Line, from where the shrine is approximately an 8-minute walk. From the central Uwajima Station, it is roughly a 20-minute walk along the Sugagawa River, or about 10 minutes by local bus. A parking area is available for those arriving by car.
Spring and autumn are particularly pleasant times to visit, although the evergreen trees themselves look striking in any season. If you can plan your trip around the autumn festival on 16 October, you will witness an atmospheric mix of ancient ritual and lively local celebration.
Around the Area
Hachimanjinja Shrine pairs naturally with several other notable destinations in central Uwajima.
Warei Shrine lies just a 15 to 20-minute walk along the Sugagawa River. It is the headquarters of the Warei faith, widely revered across Shikoku and the Chugoku region as a guardian of fisheries and industry. Its enormous granite torii gate is celebrated as one of the largest of its kind in Japan.
Uwajima Castle, originally built by Tōdō Takatora in 1601 and later associated with the Date family, is one of only twelve surviving original castle keeps in Japan. The climb up its hill rewards visitors with panoramic views of the city and the Bungo Channel beyond.
Tensha-en Garden, a beautifully designed Edo-period stroll garden built for the retired lord of Uwajima Domain, is a peaceful spot famous for its wisteria trellises and seasonal flowers.
For local cuisine, do try Uwajima-style tai-meshi, a unique sashimi-on-rice dish in which raw sea bream is mixed with a soy-and-egg sauce and poured over warm rice. Restaurants near Uwajima Station serve excellent versions, and the road station Kisaiya Square is a great one-stop place for souvenirs and regional specialities.
