Easy solution: just don't change your name! Our boys have my last name and our girls (if we'd had any) would have had my wife's last name. We didn't have girls so I don't have data on how that would've worked but seems line a no-brainer to me.

Having read about Japanese marriages, I assume that women are often thinking something like like: "There's no way I'm going to have the kind of marriage that involves changing my name. Another kind of marriage maybe BUT NOT THAT KIND."

If my assumption is wrong and they're instead thinking "I'd quite like that kind of marriage in general, but I'm not going to change my name", then there's an easy fix, as you suggest.

By law, married partners must share the same last name in Japan. It is rare, but possible for the man to change his name.

This is important for the official family register.

So not changing a name is literally not an option.

And in Japan, the land of paperwork, changing your name is a whole lot of paperwork and headaches.
