Work and still do parenting as a dad in Japan, possible? Any dads with experience?

I have a 1½ year old child and my wife is Japanese, we live in Europe.

I love being a father and spend time with my son. It's easy for us to spend time with our son, because here we have lots of vacation days and parental leave. We (mostly I) can quit work early everyday, and pick him up from preschool. My job is very flexible and mostly remote, I'm a software developer. I have a great bond with my son and appreciate my time with him, I'm so thankful for that.

However, we are planning on moving to Japan maybe in near future because my wife miss her country & family. We lived in my country a few years now so it's only right to let us live in her country (Japan).

My question is, if we work there, can I still have time with my child? How does it look for a dad that works there? I'm really torn that I have to give up precious time with him, and I hope I can still be a good father with a bond with him.

Obviously I know that there is more work hours there, but how bad is it? Do people let people go eariler if they have kids to take care of, or is that out of the window and only for the mom? I've been in Japan a few times, even in a open preschool, and it was only moms there, all the fathers were working.

I'm afraid I will lose my connection to my son if we move there.
