It was more of a global thing in Japan. Many workers actually did half a day on Saturday, so naturally were schools. Most of companies adopted 5 working day per week perhaps around the end of 80th.
School was a bit late on this one, when I was in Japan (1st year in middle school; 1992) was when they were start transitioning from 5.5 to 5. Although, I have only experienced having only second Saturday of a month off.
After I left Japan, in 1995, they've transitioned to 2nd and 4th Saturdays off, but It was not until 2002 schools in Japan transitioned to complete 5 day a week schedule.
