Abstract
In this presentation, the total fertility rate (TFR) of foreign mothers is considered in order to examine their impact on the number of births and TFR in Japan. TFR of foreign mothers in Japan is well below the replacement level as opposed to that in Europe, where it is above the replacement level. The impact of TFR of foreign mothers on Japan’s TFR was rather small, and it resulted in reducing the TFR rather than increasing it.
