Designated Sites in Japan

At present, 11 sites in Japan are designated as GIAHS. The information on these sites is available as follows.
Shizuoka, Nisi-Awa, Osaki, Takachihogo-Shiibayama, Minabe-Tanabe, Nagara River, Usa, Aso, Kakegawa, Noto, Sado

Shizuoka Wasabi Cultivating Region in Shizuoka Prefecture

Wasabi (Japanese horseradish), an indispensable condiment used in Japanese cuisine such as sushi, is a native Japanese plant first cultivated in Shizuoka Prefecture about 400 years ago. In this heavily forested area, where agriculture is difficult, terraced wasabi fields were created on mountain slopes alongside streams. A technique was developed to produce high-quality wasabi using the nutrients contained in the abundant spring water, while using as little fertilizer as possible.

Nisi‐Awa Area In Tokushima prefecture

The "Nishi-Awa" area is a mountainous region in western Tokushima Prefecture where agriculture is practiced on steep slopes with grades of up to 40 degrees without terraced fields. Efforts have been made to minimize soil erosion due to wind and rain by plowing grass taken from grasslands into the soil. Farmers have also adapted to the mountainous environment by using mixed farming: combining small amounts of multiple crops, such as buckwheat and other grains and traditional vegetables and fruits.

Osaki region in Miyagi Prefecture

The Osaki region in Miyagi Prefecture has traditionally been a rice-growing area. However, crops in the region are prone to being damaged by cold, damp seasonal winds and by floods and droughts resulting from the area’s topography. Unique ways of coping with these conditions have been passed down through the generations, such as raising water levels in the rice paddies to protect the rice ears from the cold, using heated water and building flood control basins.

Takachihogo‐Shiibayama region in Miyazaki Prefecture

Under the environment which provides few flat lands enclosed by the peaks, people have been making a living through the establishment of a composite management system of agriculture and forestry which combines timber production in planted forests, shiitake mushroom cultivation utilizing broadleaved trees, high‐quality beef cattle raising, tea cultivation and terraced rice growing, etc.. Hillside irrigation which extend to 500km on the high altitude slopes have supplied water to ensure agricultural practices, and have protected villages from disaster by draining the rainwater flowing down the slopes of the mountains.

Minabe‐Tanabe region in Wakayama Prefecture

Most of the Minabe‐Tanabe region is occupied by steeply inclined mountains with rudaceous soils, which are poor in nutrients. Trees of Ume (Prunus mume) were planted while preserving the forests for fuel of Quercus phillyraeoideson, and high‐quality ume has been produced.

The upper and middle basin of the Nagara River in Gifu Prefecture

The Nagara River in Gifu Prefecture is one of Japan's clearest rivers, with active inland water fisheries, particularly the fishing of ayu (Japanese sweetfish). Many traditional ayu fishing techniques, including cormorant fishing, have been passed down for generations. Local dishes incorporating ayu are a well-established part of the area’s cuisine. In addition, traditional crafts that make use of the river’s abundance of clear water, such as "Mino washi" (Japanese paper) making and "Gujo honzome" (indigo dyeing) continue to be practiced. All of these factors form a sustainable system distinctive to the Nagara River.

Kunisaki Peninsula Usa area in Oita Prefecture

The Kunisaki Peninsula Usa area in Oita Prefecture receives little rainfall. Due to the scarcity of water in the area, efforts have been made to use land and water efficiently by linking small irrigation ponds as a means of stabilizing the agricultural water supply. Sawtooth oak forests near the ponds conserve the ponds’ headwaters and create unique scenery. The water supplied by the ponds supports paddy field farming of rice and of a plant called “shichitoi” which is used locally to make tatami mats.

Aso region in Kumamoto Prefecture

One of Japan's largest grassland areas stretches across the Aso region in Kumamoto Prefecture. The grasslands have been used to raise cows and horses for more than 1,000 years. Even today, these vast grasslands are managed using traditional techniques, such as field burning, grazing, and mowing, to produce local specialties including "Akaushi" (Japanese brown cattle) and "Aso-takana" (a local leaf mustard which is often pickled).

Kakegawa and surrounding region in Shizuoka Prefecture

Shizuoka Prefecture is one of Japan's largest tea production areas. Four cities and one town in the prefecture maintain the traditional agricultural method of taking pampas grass and bamboo grass―referred to as "chagusa" (tea-grass)―from grasslands dotting around the tea fields for use as organic fertilizer in the tea fields. This method contributes to the health of the tea trees and enhances the flavor of the teas produced. Chagusa is indispensable for tea cultivation in the region, not only by making the soil fertile, but also by providing various other benefits, such as preventing soil run-off. The condition of these grasslands―which are inhabited by a large number of rare species of organisms―has been maintained by the mowing of the chagusa. It is a rare example of codependence between farming and biodiversity.

Noto Peninsula is characterized by terraced rice‐fields including “Shiroyone Senmaida” in the steep slopes facing the Sea of Japan, and Magaki, fence made of bamboo, to protect houses against harsh salt wind. They represent the farming, fishing and mountain villages indigenous to Japan.

Sado City in Niigata Prefecture

Sado City, which covers the entirety of Sado Island in Niigata Prefecture, is one of the very few places in Japan inhabited by "toki" (Japanese crested ibis). As part of Sado Island’s wildlife diversity promotion efforts, it undertakes initiatives to maintain biodiversity in paddy fields throughout the island, which are the habitat of the loaches on which toki mainly feed. For example, when paddy fields are temporarily drained in midsummer, deep water areas called "e" are created to allow creatures to evacuate, helping to create an environment in which organisms can thrive year around.
