I have a Japanese girlfriend, and upon asking her she didn't even know
what abortion was! When I explained it to her in my somewhat limited
Japanese, she said Japanese people tend to not have abortions...then
again she has 2 brothers and 2 sisters so maybe that's just them! Haha.
I've been here for 4 years, and not once in the Japanese papers have I
seen anything related to abortion or the pill. Hope that helps!
