It seems it's starting to change. Currently I'm leaving the company which indeed has 6 days work week (with the 6 hr Saturday) and literally every opening I'm seeing right now is 5d.
Maybe I'm biased though as I'm looking for jobs in IT companies or departments.
I don’t miss those cramped conference rooms, one tiny bit.
But they run their meetings in a very organized fashion. Everyone has their marching orders, when the meeting is done.
Japanese corporations tend to use a consensus-based system, where meetings are confirmation of consensus. Being at a meeting, meant that you were part of the stakeholders, and also part of the accountable parties.
Many times, people sleep in meetings. Their presence is all that is required.
