Childrearing is an invaluable time for the family, an integral part of life itself
That said, things were very difficult for us after our children were born. In the first month after our second child was born, I had such a hard time balancing work and childrearing that I lost five kilograms. As I was in charge of picking up and dropping off our first child at nursery school, I would have to leave work for a while to pick him up, take him home, bathe him, then go back to work. On numerous occasions, I would have to respond on the spur of the moment when one or both of them developed a fever or something. In such cases, I was really helped by Sony's childcare system (*1). It goes without saying that this system allows people to work on a flextime basis, but the long-term childcare leave and the flexi-holiday systems are also really helpful for working couples. Sony has a long-standing, deep-rooted culture that values its employees' private lives, so there is no workplace opposition when employees take time off to refresh themselves or look after their children (*2). I believe this environment makes it much easier for parents to participate in rearing their children. The fact that my wife also works for Sony makes it easier for us to do things together, and since our holidays are the same, it is also easier to plan family time.
Many male employees still find it difficult to make use of the childcare leave system, but once they have children, it is very important for fathers to take charge of the children overnight on weekends to give mothers some time of their own. Sometimes babies cry throughout the night and have to be looked after constantly, making it difficult for parents to sleep. Since mothers who have just given birth may find things difficult emotionally, fathers must also understand how tough raising children can be. Childrearing is not simply a matter of spending time with the family. It is a vitally important family time, part of one's own life. You can do much better at work if your own family life is happy.
