I think you underestimate the relative skills/responsibilities of flight attendants vs. female Japanese office workers. They former are trained in airplane security and first aid. The latter are just administrative assistants -- even the few ones that can speak English aren't trained to be translators, for instance.
For what is worth, I use US or Canada airlines because their Tokyo-N.America-Sao Paulo flights are way cheaper than the good Asian ones (as in U$1500 instead of $2000).
