It really depends on the culture of the company. In my company (95% Japanese/non-gaishiki-kei) it’s the norm for people to take a couple months off when there’s a new addition to the family. I took 6 weeks when my son was born and nobody batted an eye. My friend, who also had a child around the same time me, couldn’t take parental leave, but said he’d be working remotely a lot instead.

I’m optimistic it will change, but probably not for another long while.
