Geographical/topographical features
This Recreation Forest encompasses the Boroishi and Tokuso mountains, along with the Kaeda Valley, which lies between them.
Geologically speaking, Mount Boroishi is made up of sandstone and conglomerate, with a particularly high proportion of the latter. As a result, the mountain has many lofty, strangely shaped rocks. The most distinctive of these include Tengu-iwa Rock (named for its resemblance to a goblin), Zo-no-hakaba (“Elephant's Graveyard,” a belt of massive stones), Karaike (a huge wall of rock), and Hari-no-mimi (“Ear of the Needle,” a cave). These unusual names rarely fail to delight visitors to this area.
Historical/cultural features
From ancient times, Mount Boroishi was regarded as a sacred mountain by adherents of Japan's tradition of mountain worship. Sites where practitioners of Shugendo undertook ascetic practices and the remains thereof can be found throughout the area beyond Ubagatake Shrine (known affectionately to locals as Bira-no-gongen-sama), which is located on the western side of the Recreation Forest and is believed to have been founded in 1776. Interestingly, the sacred water drawn within the precincts of Ubagatake Shrine is called the Water of Kokonobira-no-gongen and, legend has it, will produce a bountiful harvest if sprinkled on fields and rice paddies. In 1969, Mount Boroishi was awarded the designation of National Historic Site, Place of Scenic Beauty, and Natural Monuments, as a location where a virgin laurel forest still remains.
Climate, flora and fauna
This Recreation Forest mainly consists of natural stands of subtropical broad-leaved trees, mostly composed of laurels such as tsuburajii, Japanese chinquapin (Castanopsis cuspidata), live (evergreen) oaks, and tabunoki (Machilus thunbergii).
The forest's plant life includes kibananohototogisu (Tricyrtis flava Maxim.) and hyugagiboshi (Hosta kikutii var. kikutii). Among the animals that can be seen here are yamane, Japanese dormouse (Glirulus japonicus) and Kyushu musasabi, Japanese giant flying squirrel (Petaurista leucogenys), while bird species include koshijiroyamadori, Ijima copper pheasant (Phasianus soemmerringii ijimae); kiji, green pheasant (Phasianus versicolor); aogera, Japanese green woodpecker (Picus awokera); and akashobin, ruddy kingfisher (Halcyon coromanda).
Mountain climbing: Located about 30 minutes from the Shiozuru and Kotani trailheads, with Tengu-iwa Rock towering up behind it, Iwaya Shrine is venerated as the “Ear of the Needle Shrine,” due to a legend that it has the power to heal otherwise-incurable diseases of the ear. Further on can be found Karaike, a depression surrounded on all four sides by large rocks. Those who continue on toward the summit can enjoy a panoramic view of central Miyazaki City from the No. 2 Observation Platform if the weather is fine.
20 minutes southwest of the No. 2 Observation Platform is a mountain hut, with the summit of Mount Boroishi another 25 minutes from there, at an elevation of 509 m.
Valley: From the Maruno Parking Lot north of the Recreation Forest, the Kaeda Valley stretches for 9.4 km, ending close to Tsubakiyama Forest Park to the southwest of the forest. The valley has a diverse array of strangely shaped rocks formed by water erosion and its beauty has led to its being nicknamed the “Hyuga Line”.
Visitors can enjoy a round-trip walk from the Maruno Parking Lot, thanks to a footpath developed on what was once the forest railway in the days when forestry was at its height in this area. The path runs from Hyotan-buchi (a pool of clear, blue water with a mystical beauty, named for its resemblance to a gourd) and takes in Iodani (a valley named for the sulfur-rich cold mineral spring that bubbles up here), Amacha-no-Izumi (“Sweet Tea Spring”), Shibaseki (the remains of a dam built to transport felled logs downstream), Sei-no-tani (“Silent Valley”), and the Multi-purpose Plaza (formerly the Kaeda Campsite and still used as a place of rest and relaxation today).
From Kaichigo Bridge No.1, visitors can enjoy the footpath further and reach its end near Tsubakiyama Forest Park, or, mountain trail to the Hanakiriyama.
Since 2013, the Miyazaki Kagamizunomori Trail Run has been held in May each year, with around 150 people taking part.
Latest Information
The paths are highly treacherous underfoot in places, so please take adequate care while walking.
