Outline of Final Research Achievements

The Great East Japan Earthquake made a realization of non-Japanese female living dispersed in rural areas across Japan. They are the immigrant wives, mostly Chinese and Filipino, married to Japanese men and live in local communities, isolated from the other non-Japanese residents. This study analyses their distribution pattern by using the Grid Square Statistics of 2010 Population Census and GIS. This study uses statistics of 1km x 1km grids and identifies the grid which have only one non-Japanese and that person is female as “isolated-grid”. In the isolated-grids, there are grids where no foreigners live in the 8 adjacent grids. This study identifies such a grid as “more-isolated-grid”. As a result of the analysis using the kernel density estimation method, isolated-grids are distributed in eastern Japan such as Tohoku region, but more-isolated-grids are found not only in eastern Japan but also in western Japan such as Kyushu.
