After the growth that had been recorded since 2015, the number of Portuguese entries in Japan fell again in 2018 (-11.3%), although the number of foreign entries continued to grow. In 2017 the number of Portuguese emigrants entering Japanese territory had reached the highest figure of this century (292 entries), very different from the 94 entries recorded in 2011 (minimum value of the series under analysis). Portuguese emigration to Japan remains very low both in absolute terms, in the hundreds, and relative terms.
