Tokyo Will Rent You a Nine-Million-House Country for Cheap; Paris Will Just Pay You to Have the Baby

🇯🇵 Japan · 🇫🇷 France

By Priya Mehta, The Global Office

Japan has roughly nine million empty houses and some of the most affordable big-city rent in the developed world, and yet its birth rate keeps sliding. France spends nearly 4% of GDP propping up families with cash, subsidized crèches, and a reimbursement system so generous it makes private insurance optional — and its birth rate, while also falling, has fallen more slowly. The lesson for anyone relocating is blunt: cheap housing and generous welfare are not substitutes for each other, and which one your new country picked will shape your monthly budget far more than your salary will.

Japan: Cheap Shelter, Expensive Belonging

Japan's residential math is almost anti-intuitive by global-city standards. A single person's typical monthly spend sits around $1,097 and a family's around $2,818, according to figures compiled by [Remitly](https://www.remitly.com/blog/immigration/cost-of-living-in-japan/), and a three-bedroom apartment outside the center averages roughly $1,251 — genuinely affordable for a G7 capital region. The catch is structural: Japan's government in-kind spending on early childhood education and care sat at 0.8% of GDP in 2019, per [OECD](https://www.oecd.org/content/dam/oecd/en/publications/reports/2024/04/addressing-demographic-headwinds-in-japan-a-long-term-perspective_85b9a67f/96648955-en.pdf), matching the OECD average but well below France's commitment — and licensed daycare spots are allocated competitively, not simply purchased.

Tokyo has layered on local top-ups: the metropolitan government's "0-18 Support" pays an extra ¥5,000 per month per child under 18 regardless of income, and a nationwide "Childcare for All Children" hourly-care program launches in April 2026 to help working parents outside the traditional hoikuen system, according to [e-Housing](https://e-housing.jp/post/tokyo-childcare-subsidies-2025-how-expats-can-save-yen1-2m-yearly). But these are patches on a system where the fundamental offer is cheap square footage, not guaranteed institutional support — you get an affordable apartment, and then you compete for the childcare slot to go with it.

France: Expensive Shelter, Subsidized Everything Else

France runs the inverse trade. Housing is, per multiple relocation guides including [relocate.me](https://relocate.me/cost-of-living/france), consistently the largest and most complex line item in a household budget, with family living costs commonly landing between €4,000 and €5,500+ a month in Paris. What softens that number is a welfare architecture built specifically to absorb it: the CAF distributes family benefits scaled to household income and child count with no employment requirement from the second child, and private crèche costs that nominally average €708 a month are routinely subsidized down below €200 for eligible families, according to [Ibanista](https://www.ibanista.com/caf-what-you-need-to-know-about-the-french-benefits/) and [franceadmin.com](https://franceadmin.com/family-and-housing-benefits-in-france/).

Healthcare follows the same logic of nominal cost plus systematic reimbursement. The carte vitale, available after three months of residency, plugs new arrivals into Sécurité Sociale's reimbursement model — you generally still pay upfront at the point of care, then get money back, per [The Local France](https://www.thelocal.fr/20190418/how-to-get-a-carte-vitale-and-why-you-need-one-in-france/) — and most residents layer a mutuelle top-up policy on top since base reimbursement isn't total. France's overall family policy spend approaches 4% of GDP, more than double Japan's comparable commitment, and it shows in how thoroughly the state re-enters the picture after the rent check clears.

The Reckoning

Put the two systems side by side and the counterintuitive finding is that "welfare state" and "affordable" are not the same axis. Japan is affordable and thin on family support; France is expensive and thick with it. A single professional without children will often find Japan the objectively cheaper move — lower rent, lower baseline cost of living, minimal need to navigate subsidy paperwork. A dual-income household planning a family may find France cheaper in the way that matters, once CAF, crèche subsidies, and reimbursed healthcare are netted against the higher sticker price of everything else.

Hofstede Insights scores France notably higher than Japan on individualism, and it shows up here in an unexpected place: French welfare, despite its bureaucratic reputation, is built around explicit, claimable, individual entitlements you actively apply for. Japan's system leans more on employer-provided coverage and municipal discretion, with the state's role often implicit until you go looking for it — which means the Japan move rewards people who do their paperwork early, and the France move rewards people who don't mind paperwork at all.

The Part the Brochure Left Out

Quora — A parent comparing Tokyo and Paris living costs for a family of four wrote that Tokyo's rent looked "too good to be true" until they hit the hoikuen waiting list — the daycare application, not the apartment hunt, was the actual bottleneck in relocating with young children.

The Local France — One newly arrived resident described the three-month gap between landing in France and becoming eligible for a carte vitale as the most stressful stretch of the move, since private travel insurance has to bridge that window and doesn't always cover routine care the way Sécurité Sociale eventually will.

Reddit — An expat who moved from Paris to Tokyo noted that the "empty houses" statistic is real but misleading — good, well-located apartments in central Tokyo still get multiple applications, and landlords can be selective about foreign tenants regardless of the citywide vacancy numbers.

Quora — Someone weighing a France move said the pleasant surprise wasn't the healthcare, which they'd expected, but the housing benefit (APL) applying even to moderate earners, meaningfully softening a Paris rent that had looked unworkable on the salary alone.

Reddit — A parent in Japan described the flat-rate Tokyo child subsidy as "nice pocket money" but said it doesn't come close to offsetting the real cost driver, which is private school and juku (cram school) fees once children hit school age — the welfare system covers early years generously in France and much more thinly in Japan.

Conclusion

The honest advice for anyone comparing these two moves is to price the life stage you're actually in, not the country's reputation. Japan rewards single professionals and punishes procrastination on daycare applications; France punishes anyone who hasn't budgeted for Paris rent and rewards anyone willing to fill out CAF paperwork. Both countries call themselves welfare states. Only one of them means it at the checkbook level for families — and it's not the one with the empty houses.
