> Kids in Japan lead carefree "be home by dark" lives up until late middle school and high school, when they start studying 4+hrs/day and sleeping <5hrs/night to prep for standardized tests.

In my experience the same's true for upper-middle class Americans.

I've never heard of anything outside of a few edge cases doing anything like that here. It's definitely not the norm for upper-middle class kids.
