An important component of “Abenomics” was trying to increase the fertility rate - Japan has been infamously careening towards demographic collapse (which ya know, might be connected to getting married/having kids torpedoing a career…)

At least Abe was advocating consensual sex, I don’t know if his grandfather was so kind in Manchukuo. Abe certainly didn’t want anyone to know about what was happening in Manchukuo.
