Yufuta-no-mori and Kinukake-no-mori: Two Camphor Giants at Umi Hachimangu

Each of these is a single camphor tree, yet each carries the word mori, "grove" or "forest," in its name. Stand beneath either one and the reason is obvious. The trunks are so broad and the canopies so wide that a lone tree fills the space of a small wood. The two grow in the precinct of Umi Hachimangu, a shrine in Umi, Kasuya District, Fukuoka Prefecture, on the island of Kyushu. Both were designated National Natural Monuments on March 8, 1922.

They belong to the species Cinnamomum camphora, the camphor tree, called kusunoki in Japanese. Camphor is the great evergreen of warm southwestern Japan, and old specimens often outlive the buildings around them. These two are among the largest the country has. Yufuta-no-mori stands to the right of the main hall as you face it, and Kinukake-no-mori to the left, so that the shrine sits between two living pillars.

A Shrine Named for a Birth

To understand why the trees matter, it helps to know the place. Umi Hachimangu is dedicated to Empress Jingu and her son Emperor Ojin, a mother-and-child pair venerated together. According to the eighth-century chronicles Kojiki and Nihon Shoki, Empress Jingu gave birth to Ojin at this spot after returning from a military campaign on the Korean peninsula. The old name of the area was Kada. The name Umi is read the same as the verb umi, "to give birth," and tradition links the two directly.

That origin made the shrine a center of belief in safe childbirth and the healthy raising of children, a role it still fills today. Expectant families come from across the region, and the grounds are dotted with objects tied to the birth legend: a stone for safe delivery, a sacred tree, a spring said to have supplied the newborn's first bath.

The two camphors are woven into that same story. A text of 1689, the Hachiman Hongi attributed to the scholar Kaibara Yoshifuru, records that when Empress Jingu gave birth, a camphor grew beside the birthing house; the infant Ojin was bathed beneath it, and its branches spread above like a lid over the water. People later called that tree Yufuta-no-mori, "the grove of the bath canopy." The tree on which the baby's first robe was hung became Kinukake-no-mori, "the grove of the hung robe." The names are not decoration. They fix each tree to a moment in the legend.

Why They Were Designated

The 1922 designation falls under the criterion covering famous trees, giant trees, aged trees, and shrine groves. The grounds of the protection were straightforward: these are camphors of exceptional size and age, growing in their original sacred setting rather than transplanted or isolated.

The early survey that supported the listing, the Report on the Investigation of Natural Monuments (Botanical Section), Volume 2, recorded the measurements in the units of the day. The trunk girth of each, taken at a height of five shaku (about 1.5 meters) above the ground outside the stone railing, came to five jo five shaku, roughly 16.7 meters around. The same report noted that Yufuta-no-mori's main trunk was already considerably decayed because of its age, a candid observation that tells you these were treated as living antiquities even a century ago.

Modern figures vary, as they do for any tree this old, since girth depends on exactly where it is measured and how the buttressed base is read. Yufuta-no-mori is commonly given a circumference near 15.7 meters and Kinukake-no-mori near 20 meters, with both rising to about 20 meters tall. Ages are estimates rather than counts: many guides put the trees at over a thousand years, while the shrine and the town hold that they exceed two thousand. The honest answer is that no one can be sure, and the uncertainty is part of what makes standing under them affecting.

What to Look For

The two trees reward different kinds of attention. Yufuta-no-mori, on the right, has a fuller, more open crown, its limbs reaching upward and outward in a way visitors often describe as welcoming. Its great age shows in the hollows and weathered grain of the lower trunk, the same decay the 1922 surveyors noted, now a feature rather than a flaw.

Kinukake-no-mori, on the left, is the more dramatic of the pair. The base flares into massive ribs and folds of bark, a knotted, sculptural mass that reads less like a single trunk than like several fused together. Come early on a quiet morning and the contrast between the two is easy to feel: one expansive, one fierce.

Look up, too. Camphor leaves release a faint medicinal scent when crushed, the source of natural camphor, and on a warm day the air around the trees carries a trace of it. The shrine precinct holds more than thirty camphors in all, so the two monuments are the elders of a much larger family. One of the others, known as Kada-no-mori, is itself protected as a prefectural natural monument.

Around the Shrine

Umi Hachimangu sits in the middle of Umi town, easy to combine with other stops. The Umi Town Museum of History and Folklore stands just south of the precinct and is a short walk; it sets the shrine and its trees in the wider story of the area. To the north of town rises Mount Shioji, with a prefectural forest park offering trails and views over the Fukuoka plain.

The shrine grounds are open and free to enter, and the two camphors can be visited at any time of day. The trees are popular backdrops for the families who come to pray for an easy birth, so weekends and auspicious days can be lively. A weekday morning is the quieter choice if you want them to yourself.

By train, the shrine is about a nine-minute walk, roughly 750 meters, from Umi Station on the JR Kashii Line. By car, it lies about 6.5 kilometers from the Dazaifu interchange on the Kyushu Expressway, or about 3 kilometers from the Sue Smart interchange, with parking on site. Dazaifu itself, with its famous Tenmangu shrine, is within a short drive and pairs naturally with a visit here.
