It's too expensive to have a kid in Japan. There aren't enough childcare to take care of the kids so one parent usually ends up staying home, making household income low.
Japan can't fix this by having bandage solutions like paying couples to have children, or subsidizing deliveries or schools. Yes, they help, but only in the short term. Prospective parents will think about long term prospects and opportunity cost in having kids. Japan has change the whole system to make it work for couples to have kids.
