Well, not the usual biz life, but my wife and I as uni teachers generally had flexible schedules and certainly no evening overtime (thru the 90s and 2000s). Occasional weekend work and some other similar things.
For us, for the daycare we used, the notebooks passed back and forth were only partially data driven (times things happened, etc.), The more important part were the stories/reports/descriptions of what happened or what they did at home or at daycare. This record was especially insightful and eye-opening to one daughter (who is now a mother has read thru her whole daycare life)--to see what we and she were experiencing then. The good and the bad, her development there over the years, and so on.
For all the angst about how tough it is, this daughter got a year off from work at about half pay (in biz, not teaching), and got the same job back afterwards. She's due again, and is planning to do the same thing, again. That's unheard of in the states.
Daycare/保育園 in japan is a huge bargain, even more so when you have two going simultaneously (hint: it's not double, but costs about the same). I've heard that a week of daycare in the US can easily cost more than a month's worth in Japan--and two kids cost twice as much.
