See the real, stage-by-stage cost of raising a child through Japan's school system — 保育園 (hoikuen) to 塾 (juku) — and the 幼保無償化 and 児童手当 support you get back. In plain English.
Costs here are ranges from published statistics (文部科学省 子供の学習費調査 and official rules), not quotes. 保育料 is set by your municipality and income — we give the mechanism and a band, then point you to your city for the exact figure.
