>>299344Not sure I have this right but a reason that was explained to me:
voice training for actresses and voiceactresses in Japan came almost immediately on the heels of westernization in the Meiji era.
That means that training for women was adapted from three extreme sources:
–the voice training MALES would get when they were expected to perform female roles in exaggerated falsetto
–the voice training given to non-geisha prostitutes (specifically higher income "goke" widows–older women with worn down and more haggard natural voices). This was intended to be specifically artificial to take the client out of the headspace of interacting with a normal person so that they wouldn't be thinking "this is a widow or a divorcee, she has kids, she is old enough to be my own mom or my aunt–". This was also aimed at making them sound like they were 20 again, since we're talking about a type of prostitutes who were generally late 30s to early 50s in age. These techniques when applied by women who were 20-30 and nonsmokers sent the target age much lower.
–Most foundational anime from the 40s through the 70s genuinely was targeted at children and most voice actresses had to be able to take on children's roles for stable employment, and not all of them were capable of doing a good "boy" voice for that purpose.
