As you probably know, Japan is quite hierarchical. This is true of Japanese corporations too (particularly old, traditional organizations). This can manifest as abusive behavior from senior employees to junior employees. Nowadays there are internal guidelines against egregious abuse, but it should be no big surprise that elder/senior employees still feel entitled to speak harshly to newer employees (I think the older generation would view it as "guidance" or "leadership", and that they are only being harsh in order to teach the new employees the right way to do things). Well, those senior employees may not even view it as being "harsh". They might just do this naturally as that is how they were treated themselves when they first joined the company.
But it is an outdated way of thinking, to be sure. If your co-working company is an old-established one, the older employees may feel even more entitled to be strict with the new employees. AND, the new employees may be resigned to tolerate the abuse because the company is a prestigious one and the young employees are happy (overall) to be there. Also there is a strong cultural bias towards adapting to harsh conditions without complaint. The hope is that the tolerance will eventually pay off in some way. Its kind of how the cycle works. Someone who endures a decade or two of abuse, will be elevated to a point where that person can then abuse his own direct reports.
Again, mostly true only for old, traditional companies. And maybe organizations in rural locations. It's not true for every company.
