TL;DR
- The BOJ kept its overnight policy rate at around 1.25% on 30 October 2026; that is not a mortgage quotation.
- In the illustrative example, increasing the loan rate from 2% to 3% cuts annual cash remaining before income tax from ¥1.8 million to ¥1.2 million.
- Buyers need separate tests for operating costs, debt service and currency exposure.
The Bank of Japan’s decision to keep its short-term policy rate at around 1.25% on 30 October gives overseas property buyers a more current starting point than the near-zero borrowing assumptions that helped shape Japan’s appeal. The decision passed by eight votes to one, with the dissenting member proposing 1.5%. Source: Bank of Japan.
For someone considering an apartment in Japan, however, the policy rate is only the beginning of the calculation. A bank’s property loan carries its own pricing and conditions. What matters to the owner is the income remaining after operating expenses, financing and any conversion back into their home currency.
PNA’s analysis is that buyers should separate three questions: whether the property earns enough in yen, whether its debt remains affordable, and whether the currency exposure fits the purpose of the purchase.
What a higher loan rate does to the same property
Consider a hypothetical apartment costing ¥100 million, producing ¥4 million in annual gross rent. Assume annual operating expenses of ¥1 million and a ¥60 million interest-only loan. These are illustrative inputs, not a current listing, market average or available loan offer.
| Annual calculation | 2% loan rate | 3% loan rate |
|---|---|---|
| Gross rental income | ¥4,000,000 | ¥4,000,000 |
| Operating expenses | ¥1,000,000 | ¥1,000,000 |
| Income before financing | ¥3,000,000 | ¥3,000,000 |
| Annual interest | ¥1,200,000 | ¥1,800,000 |
| Cash remaining before income tax | ¥1,800,000 | ¥1,200,000 |
A one-percentage-point increase in the assumed loan rate reduces that remaining cash by one-third. The gross rental yield stays at 4%; the underlying income before financing stays at 3% of the purchase price. Neither measure captures the reduction in cash available to the borrower.
The example excludes acquisition and disposal costs, income tax, principal repayments and exceptional capital expenditure. An amortising loan would also require principal payments. It does not assume a one-for-one relationship between a BOJ move and a lender’s mortgage pricing.
Cash buyers still have a currency calculation
An unleveraged buyer avoids mortgage interest, but still faces repairs, vacancy and the opportunity cost of tying up capital. Foreign-exchange movements then affect both the entry price and the value of income or sale proceeds converted home.
Using purely illustrative exchange rates, a ¥100 million purchase costs S$1 million at ¥100 per Singapore dollar. At ¥90 per Singapore dollar, the same yen price costs approximately S$1.11 million. A stronger yen raises the entry cost for that new buyer; it can increase the Singapore-dollar value of an existing owner’s yen proceeds. Borrowing currency, hedging and conversion charges change the result.
The comparison to make before committing
A useful purchase assessment therefore includes a base case and a weaker case: lower collected rent, an empty period, higher management or repair costs, and the financing terms that apply when the loan resets or matures. The owner should also identify which expenses are paid in yen and which obligations must be met elsewhere.
The BOJ decision does not establish that Japanese property prices will fall. It makes the quality of an individual purchase calculation more consequential. A home bought primarily for personal use and an apartment bought for income can justify different decisions, even at the same address.

Frequently asked questions
Is Japan’s 1.25% policy rate the rate a property buyer will pay?
No. The BOJ’s policy target concerns the overnight call rate. Individual lenders set property-loan rates and conditions separately.
How does a higher mortgage rate affect the example?
On the hypothetical ¥60 million interest-only loan, a rise from 2% to 3% adds ¥600,000 to annual interest. Cash remaining before income tax falls by one-third, from ¥1.8 million to ¥1.2 million.
Do cash buyers avoid all of these risks?
They avoid mortgage interest, but still face vacancy, repairs, ownership costs and currency movements. A stronger yen can increase a new buyer’s entry cost in Singapore dollars.
Does the BOJ decision mean Japanese property prices will fall?
No. A policy-rate decision does not establish the direction of individual property prices. Location, income, condition, financing and the buyer’s intended use still matter.
