[G05-P08] Effective use of igneous rock in Naeba-Sanroku Geopark

*Kouhei Nakano

Keywords:Stone Wall Field in Ketto

Using igneous rock , which is the material of Earth, our ancestors made Stone Wall Field rice fields to grow rice and prevent famine.

On the north side of the Ketto village, there are beautiful stone wall fields which have been selected as one of the 100 best rural landscapes in Japan. The stone walls, which were built over many years and with great effort, utilizes the collapsed rockfall of the volcanic ejecta (columnar joints) of Mt. Torikabuto and Mt. Naeba.
Clearing of this land began around 1892, when Akiyama-go was considered to be a harsh environment for rice cultivation, but with determination,the villagers created these stone wall fields with blood and sweat.
Currently, the number of rice fields that are not cultivated is increasing due to the difficulty of farming work and the aging of villagers because the surrounding farm roads are narrow and large machinery cannot be used. For this reason, a preservation society has been established to carry out conservation activities in cooperation with residents and the government, and also to experience farming in collaboration with ecotourism.
In order to let many people know the wonderfulness of these stone wall field fields, we light 1,000 candles on the stone wall fields after planting rice and enjoy the spring evening with the Crow Dance (indigenous folk song), and hold other events.
In addition, "wind holes" are scattered in the talus slope at the base of the igneous rock wall, and rare plants such as Lonicera(honeysuckle)tschonoskii grow.
It is a wonderful spot where geo, eco and culture converge.
