Along with these movements, the Arakaki Report was published in 2015 and made great progress in analyzing and discussing statelessness in Japan, which had been lagging behind as compared to some other countries. Taking this favorable opportunity, this report offers a comprehensive overview of the situation which the Abe Report had previously described through the lens of “typology”, with an intention to further approach “mapping” in a real sense.

It also analyzes the causes and current situation of these and discusses and presents some recommendations towards solutions for each category. 15
