If they are just compress the 40 hours down to 4 days, then this won't work. I don't know how it works in Japan, but how the hell are you suppose to drop off and pick up kids with a 10 hour day, are schools and daycare even available 11-12 hours per day? They'd be increasing the stress four days a week to an ungodly level where families won't be able to function. Most of these four-day workweeks are almost always bullshit, because they insist on keeping the same hours. I hope that's not the case here. Some companies have been experimenting with just slashing a day a week completely and it always increase productivity, retention and happiness.
