This document summarizes Japan's immigration policy and the conflicting pressures it faces. Historically, Japan favored a homogeneous society and avoided foreign labor. However, factors like an aging population, labor shortages, and globalization are pushing for more open immigration. At the same time, concerns over security and crime are prompting stricter controls. The government reformed policy in 1989 to facilitate skilled workers while maintaining the principle against unskilled labor. Recent amendments aim to reduce unauthorized residents due to perceptions they increase crime, such as through stricter entry exams and deportation procedures.
