Overview
Geographical/topographical features
[Osorakan District]
The district is part of the Nishi-Chugoku Sanchi Quasi-National Park and encompasses Mt. Osorakan (1,346 m), which straddles the border between Hiroshima and Shimane Prefectures. Its summit is the highest peak in both prefectures.
[Hosomi-kyo District]
The district is part of the Nishi-Chugoku Sanchi Quasi-National Park. It also includes the Hosomi Valley to the west of Mt. Jippo (1,318 m), a high peak near the border between Hiroshima and Shimane Prefectures. It has so many gorges that it has been referred to as the place of "808 valleys." Despite the steep landscape, the area is a popular mountain stream fishing spot.
Historical/cultural features
[Osorakan District]
The Osorakan District flourished as one of Japan's largest iron production areas until around the mid-1950s. The major iron production method used was Japan's traditional manual method called tatara iron making.
In this method, iron-sand and charcoal were placed in a clay furnace that was kept burning for three days and nights while a constant amount of wind was continuously fed into it.
This required a tremendous amount of charcoal and manpower. The sites where wood for the charcoal was logged can be seen today in the terraced fields and along the Osorakan Trail.
Climate, flora and fauna
[Osorakan District]
The district is covered by a vast primeval forest of Buna (Japanese beech (Fagus crenata Blume)), Mizunara (Japanese oak mizu-nara (Quercus crispula Blume)) and Tochinoki (Japanese horse chestnut (Aesculus turbinata Blume)).
In May, 120,000 Suisen (daffodil (Narcissus sp.)) color the ski slopes of the Osorakan Snow Park, and Mt. Osorakan is opened to hikers.
[Hosomi-kyo District]
The district has a picturesque gorge where streams contrast with early-summer green or autumn red and yellow leaves of Japanese beech, Japanese oak mizu-nara, Mizume (Japanese cherry birch (Betura grossa)) and Katsura (katsura trees (Cercidiphyllum japonicum Siebold et Zucc. ex Hoffm. et Schult.).
The district is also the southernmost habitat for Tsukinowaguma (Asian black bear (Ursus thibetanus)) on the island of Honshu.
Attractions
Akiota Town's "Forest Therapy Base" (Therapy Road) is found at the foot of Mt. Osorakan, the highest peak in both Hiroshima and Shimane Prefectures. The base offers various therapy programs, including snow-covered mountain forest therapy using snow (the ski area) in the winter.
The Osorakan Snow Park is a ski area with 100% natural snow. Visitors can enjoy skiing, snowboarding and various other thrilling snow activities.
The vast ski slopes, with an elevation difference of 420 m, have 8 chair lifts and 11 trails and offer a perfect snow experience for skiers and snowboarders of all levels.
The snow park also has a family zone where small children can have fun in the snow safely. In addition, mystic frost-covered trees can be seen on the higher ski slopes.
The Osorakan Ecology Campsite is the highest-elevation campsite in Hiroshima Prefecture.
It is fully equipped with cabins and an auto-camping site, making it easy to enjoy camping. The site also offers a variety of outdoor activities, such as zip-lining.
In Hosomi-kyo, visitors can stroll in the forest and explore nature as they camp, trek and hike in the cool air.
Meanwhile, Hosomi Gorge is known as a hidden spot perfect for mountain stream fishing for Yamame (masu salmon (Oncorhynchus masou masou)) and Iwana (Japanese char (Salvelinus leucomaenis subspp.)), attracting many fishing enthusiasts from local areas and also from outside the prefecture.
