Since the opening of the Tsukuba Express Railway Line, and alongside the booming of Mt. Tsukuba itself as a tourist destination, the areas around the foot of Mt. Tsukuba- the Satoyama land areas between the foothills and arable land and its rice paddies in the valley wetlands (or yatsuda) - have been neglected, and these original environments are being lost. Alongside this, Satoyama traditional local culture is disappearing as a result of an aging population and wider industrialization. In this activity, urban residents who feel this sense of crisis co-operate with the local community in rice cultivation in these paddy fields at the bottom of valleys. Through these exchanges, environmental conservation is carried out while Satoyama culture is maintained.
