It's not exactly mind-blowing to see that the working populace that's under the influence of extremely dogmatic bosses had a hard time readjusting to a work format that's completely foreign to them -- especially that one exact format that is widely frowned upon there, with their culture of 16h workdays and whatnot. Japan, for all the unexplained praise it gets in some media outlets, has been widely reported to be one of the worst places in the world in terms of a work-life balance. Nobody can generalize an entire country of course, but bad working conditions seem to be the default state of things there (I have several acquaintances and they all left Japan a year or so later after they started getting pressured into almost sleeping in the office). Add to that that their office culture seems centered on interruptions, the much-hated by us the devs technique of "patting you on the shoulder to check how you're progressing", and the idolization of time spent in the office as opposed to "what did you actually do?", and I could have told you that productivity as Japanese understand it took a dive. And as the currently top comment states, measuring WFH in conditions when most employees have no choice but to accept it makes for warped and likely non-objective metrics.
