Hahaki Shrine's Sacred Grove: A 400-Year-Old Chinquapin Forest in Tottori
At the foot of Mount Ōhira's northwestern hills in central Tottori Prefecture, evergreen chinquapin trees crowd around the worship halls of Hahaki Shrine. The oldest among them measure roughly 1.5 meters across the trunk at chest height and rise more than 20 meters into the canopy. The forest covers the shrine precincts and the surrounding slope, and has been protected as a National Natural Monument since May 1, 1934.
The original designation document, written in the terse classical style of the era, records trunk girths approaching six meters and notes the presence of epiphytic plants such as fūran orchids (Neofinetia falcata) and Asian jasmine vines (Trachelospermum asiaticum) growing in the upper branches. These features marked the site, in the words of the 1934 register, as a particularly outstanding example of a chinquapin shrine grove.
A Three-Tier Evergreen Canopy
Walking inward from the first torii gate, visitors enter what botanists call a sandanrinsō, a three-tier forest structure. Castanopsis sieboldii (sudajii in Japanese) makes up more than eighty percent of the tallest layer. Below it grows tabunoki (Machilus thunbergii), an aromatic broadleaf evergreen in the laurel family, alongside kuroki (Symplocos kuroki). The middle and ground layers contain yabu-tsubaki camellia, mochinoki holly, inubiwa fig, and keyaki zelkova.
What distinguishes this grove from many surviving sacred forests in western Japan is the presence of healthy seedlings and saplings of the dominant chinquapin and tabunoki species. Ecologists read this active regeneration as a sign of a climax community in stable equilibrium. In the warm-temperate evergreen forest zone of the San'in coast, intact examples of this type are now rare, and the Kurayoshi basin retains few comparable sites.
The Second Shrine of Hōki Province
Hahaki Shrine carries the rank of ni-no-miya, the second-most-prestigious shrine of the old Hōki Province that occupied today's eastern half of Tottori Prefecture. The shrine appears in the tenth-century Engishiki, a register of officially recognized cult sites compiled in 927. Its actual founding date is unrecorded.
The principal deity, Yaekotoshironushi-no-Mikoto, is a son of Ōkuninushi and a central figure in the Izumo mythological cycle. Local tradition holds that the deity landed at Wataragai, a coastal site to the west, and then opened up the surrounding agricultural lands. Eight other deities are enshrined together with him, including Shimoteruhime, Sukunabikona, and Takeminakata. The current main hall was rebuilt in 1877, and the nearby Kaita Shrine was merged into Hahaki in 1916.
An unusual detail in the shrine's history involves medicine. The Heian-period text Daidō Ruijuhō, compiled in the early ninth century, records Hahaki Shrine as the transmitter of "Hōki medicine," a folk remedy for boils, burns, and bruises. The actual recipe has not survived, but its mention in a court medical compendium points to a long entanglement between the shrine, the local flora, and community healthcare.
What to Watch For on the Grounds
Pause at the second torii before walking on. The dense canopy filters direct sunlight into a soft green glow even at midday, and the temperature drops noticeably from the surrounding streets. The largest sudajii rise on the slope just west of the main hall; their root buttresses spread across exposed stone, and the bark carries the deep vertical fissures typical of old chinquapins.
In late winter and early spring, yabu-tsubaki camellias bloom red against the dark trunks. Birdwatchers come here for forest-dwelling species including Japanese white-eye, varied tit, and great spotted woodpecker, which thrive in the climax broadleaf canopy. Photographers find the best light in the hours after dawn, when oblique rays cut through the canopy in narrow shafts and the epiphytes high in the branches catch the first sun.
Fukuba Kofun: A Tomb Within the Grove
Behind the main hall, on a rise inside the forest, sits Fukuba Kofun, a late Kofun-period circular tumulus designated a prefectural historic site in 1956. The mound measures about 35 meters in diameter and four meters in height. Its horizontal stone chamber, with a total length of 9.5 meters, remains open and accessible. The corridor section widens toward the entrance from 2.1 meters to 2.7 meters across.
What draws specialists is the chamber construction. The burial chamber proper combines large cut blocks set upright as side walls with a corbelled roof of slab stones, capped by a single thick lintel. Built in the early seventh century, the structure ranks among the most refined late-Kofun stone chambers in the San'in region. The Kyoto Imperial University archaeologist Umehara Sueji conducted a survey of the chamber in the Taishō period. One occasionally cited theory holds that the large base stone of the current shrine main hall was repurposed from a kofun cover, though the connection has not been definitively confirmed.
Around the Site
The Utsubuki-Tamagawa district, Kurayoshi's preserved quarter of white-walled storehouses and red-tiled roofs, lies about a kilometer south of the shrine. The area is nationally designated as an Important Preservation District for Groups of Traditional Buildings. Several merchant houses now operate as cafés, craft galleries, and small museums. The Kurayoshi Museum, with archaeological exhibits drawn from sites across the basin, sits within walking distance of both the shrine and the historic quarter. To the south, Mount Daisen rises on clear days as a distant landmark on the horizon.

Questions and Answers
- When is the best time of year to visit?
- The forest is evergreen and rewards visits in all seasons, but late winter through early spring brings camellia bloom under the chinquapin canopy. Fresh foliage in May and the autumn contrast with adjacent deciduous trees in November are also rewarding. The dense canopy keeps the grove several degrees cooler than the surrounding streets, so bring a light layer in any season.
- Is the grove open to the public?
- Yes. The shrine precincts and the grove are freely accessible during daylight hours, with no entrance fee. Visitors are asked to stay on marked paths and to refrain from touching, climbing, or removing any vegetation or epiphytes.
- How do I reach Hahaki Shrine from Kurayoshi Station?
- Take a city-line bus from Kurayoshi Station for about ten minutes to Kurayoshi Bus Center, then walk roughly nine minutes north. The shrine sits about one kilometer north of Kurayoshi Station, and walking the full distance from the station takes around fifteen to twenty minutes.
- Can I enter Fukuba Kofun inside the grove?
- The tumulus sits on the shrine grounds and the stone chamber is open and accessible from the outside. The interior is unlit, so a small flashlight or phone light is advisable for safe observation. The chamber remains within an active shrine precinct, and a quiet, respectful approach is expected.
- What is the chinquapin tree (sudajii)?
- Sudajii is Castanopsis sieboldii, an evergreen broadleaf tree in the beech family. It produces small edible nuts in autumn and forms the dominant canopy of warm-temperate climax forests across southwestern Japan. The specimens at Hahaki Shrine are estimated to be over 400 years old, with several individuals exceeding 1.5 meters in trunk diameter at chest height.
