Japan to Expand 'Flat 35' Mortgage Rate Cuts for Families Buying Used Homes

- Japan's transport ministry plans to strengthen 'Flat 35' long-term fixed mortgage support for child-rearing households.
- The focus is a rate cut when such families buy used homes, with funds in next year's budget request.
- The move targets two structural issues at once: the birthrate and used-home turnover.
- Taiwanese eyeing Japanese property or its mortgage system should treat this as a core signal.
If you have ever thought about buying property in Japan, note this policy direction. The transport ministry (MLIT) plans to strengthen its 'Flat 35' long-term fixed mortgage support, focusing on a rate cut for child-rearing households that buy used homes, with the money placed in next year's budget request.
Why is this a core signal for Taiwanese readers? 'Flat 35' is Japan's flagship long-term fixed-rate mortgage; once locked, repayments are predictable — a big draw for overseas buyers who don't want to bet on rate moves. The new tilt — cheaper rates for families buying used homes — targets two structural problems at once: the birthrate, and the sluggish turnover of second-hand housing.
Keep expectations calibrated. This is a policy stance plus a budget request, not a live program. Budget requests still face review, and the design centers on families and used homes, so whether and how overseas buyers qualify awaits the fine print.
Treat it as a signal, not a ready discount. Watch three numbers when the budget is finalized — the size of the rate cut, the eligibility threshold and the covered group. Those tell you whether Japan's property entry bar has really fallen, or whether this stayed a slogan.
