Genkai shūraku

Genkai shūraku is any village or hamlet within a merged town or village in Japan that has experienced depopulation and in danger of disappearing altogether, largely because half of the people living there reach the age of 65 and over.
Such villages are typically found in mountainous areas and remote islands. Communities facing these conditions have witnessed a rapid decline in local government functions, road maintenance, and ceremonial activities, and are at risk of losing these altogether.

History

Akira Ōno, a professor of emeritus at Nagano University first proposed the concept in 1991 while teaching humanities at Kōchi University.
A number of surveys have been conducted to explore the phenomenon. In 2005 the Ministry of Agriculture, Forestry and Fisheries commissioned a rural development committee to do a survey on the true state of genkai shuraku. According to the results, there were an estimated 1403 villages that were found to be in danger. These results were based on census results in agricultural villages. In April 2006, the Ministry of Land, Infrastructure, Transport and Tourism commissioned a survey on the state of depopulating areas. The report stated that, of the 62,273 villages that were visited, 775 of them were depopulating.
