What the Bank of Japan's Rate Hikes Mean for Japan STR Investors: Why Exit Prices and the Yen Matter Even for Cash Buyers

The Bank of Japan has raised its policy rate to around 1.25%, and long-term yields have reached levels not seen in about 30 years. In our view, this matters even to overseas investors who buy Japanese short-term rentals with cash, because it works through the borrowing conditions of future buyers, required yields and the yen. The impact differs sharply by property type: we expect limited upside for prices in the short term, with the medium- to long-term picture depending on how regulation reshapes supply.

1. The Short Answer

Since ending negative interest rates in March 2024, the Bank of Japan (BOJ) has raised rates step by step. With its decision on September 18, 2026, the policy rate (the target for the uncollateralized overnight call rate) reached around 1.25%. The next monetary policy meeting is scheduled for October 29 and 30. Media reports suggest the BOJ is likely to hold in October while leaving the door open to a hike in December.

In our view, rising rates are not only a concern for people who borrow to buy. Overseas investors who buy Japanese STRs (short-term rentals, such as whole-house rentals operated as minpaku (private lodging under the Housing Accommodation Business Act) or under a ryokan license (a year-round lodging permit under the Hotel Business Act)) with cash or home-currency funds are also affected through three channels:

• the borrowing conditions of domestic buyers who will be the future purchasers when you sell;
• the yields investors require; and
• the yen exchange rate.

We believe the size of the impact varies greatly by property. Low- to mid-priced properties, where buyers are mostly domestic and depend on loans, have exit prices that are sensitive to interest rates. High-end properties with strong earnings can more easily absorb higher rates through rising nightly rates and a buyer pool with more cash. In the short term, we see limited room for further price gains; over the medium to long term, we think much depends on how regulation changes supply. Below, we walk through the primary data in order.

2. How the Policy Rate Has Moved

The BOJ's published statements show the following path since 2024.

Source: Bank of Japan, statements on monetary policy.

In March 2024, the BOJ judged that negative interest rates and yield curve control had "fulfilled their roles" and ended them, also stopping new purchases of ETFs and J-REITs. In roughly two and a half years since then, the policy rate has risen to 1.25%.

Outlook for the October meeting

The BOJ holds eight policy meetings in 2026. According to its meeting schedule, the remaining ones are on October 29-30 and December 17-18, and the October meeting will also release the Outlook for Economic Activity and Prices (Outlook Report). On October 13, 2026, Bloomberg reported, citing people familiar with the matter, that the BOJ is leaning against a back-to-back hike in October while keeping December open. Market pricing on the same day was reported at about a 10% chance of an October hike and about 90% for a hike by December.

We are not in a position to forecast rates. In our view, what matters more than "when is the next hike" is that the policy rate is now above 1%, and market rates and lending rates have risen along with it, as the next section shows.

3. Market and Lending Rates: Long-Term Yields Above 3% for the First Time in About 30 Years

The policy rate is a short-term rate. What affects property prices and borrowing costs more directly are long-term yields and bank lending rates.

The average contract interest rates on loans are compiled by the BOJ from bank reports; "new" covers loans made during the month. The short-term prime rate (tanki puraimu reito) is the most favorable rate banks apply to loans of under one year to prime corporate borrowers. Flat 35 is a fixed-rate home loan of up to 35 years offered jointly by private lenders and the Japan Housing Finance Agency.

The newly issued 10-year JGB yield rose above 3% on September 1, 2026 for the first time in about 30 years, touching 3.115% intraday on September 25. Banks' new lending rates are now more than double their level when negative rates ended.

The key point for overseas investors: even if you do not borrow, your future buyer will borrow at these rates. In our experience, buyers of Japanese real estate, especially individuals and small businesses, usually rely on bank loans.

4. The Property Market: Cap Rates Have Not Moved Yet, but Investors See Rates as the Biggest Risk

Expected yields flat to slightly lower

The Japan Real Estate Institute's Real Estate Investor Survey (as of April 1, 2026; published May 27; 142 respondents) put the expected yield for Class A offices in Tokyo's Marunouchi/Otemachi at 3.2%, unchanged for the seventh consecutive survey. Studio rental apartments in southern Tokyo (Jonan) were at 3.6% and limited-service hotels in Tokyo at 4.1%, each flat or down 0.1 points from October 2025. The expected yield (cap rate) is the yield at which investors would be willing to buy; when it rises, prices fall.

But rates are the top risk

In the same survey, "rising interest rates" was the most cited future risk factor (respondents chose two), named by 122 firms. The most common forecast for the long-term rate at the end of March 2027 was "above 2% up to 3%," at 61.7%. Note that the survey was taken in April 2026, when the policy rate was 0.75% and long-term yields were below 3%. It does not reflect the June and September hikes or the move to 3%-plus long-term yields.

Transaction markets remain active

According to JLL, Japan's commercial real estate investment volume in the first half of 2026 was ¥3.7517 trillion, up 17% year on year and a record for a first half. Overseas investors accounted for 30% (¥1.1105 trillion). For hotels, JLL reports Japan's hotel investment volume in the first half of 2026 at US$1.9 billion, up 75%, the largest in Asia Pacific.

In our view, rising rents and nightly rates have so far offset rising interest rates in the professional investor market. With long-term yields now above 3%, however, we think upward pressure on yields (that is, downward pressure on prices) will start to show, especially in properties with weak income growth.

5. The Yen: Rate Hikes Do Not Necessarily Mean a Stronger Yen

For overseas investors, the exchange rate matters as much as interest rates. Below are the BOJ's monthly average USD/JPY rates (Tokyo market, 5 p.m.).

Source: Bank of Japan.

Higher Japanese rates and a narrower gap with overseas rates are generally seen as supporting the yen. In practice, however, the yen fell sharply between spring 2025 and summer 2026, while the policy rate rose from 0.5% to 1.0%. In late July 2026 the yen weakened to nearly ¥164 per dollar, and the Japanese and U.S. governments conducted coordinated yen-buying intervention on July 31 (U.S. Eastern Time), reported as the first coordinated Japan-U.S. yen-buying since 1998. Intervention from July 30 to August 26 totaled about ¥15.4 trillion, a record on a monthly basis, Kyodo News reported based on Ministry of Finance data. As of October 13, 2026, USD/JPY was trading around ¥158.

This has two implications for overseas investors:

• When buying: A weak yen makes Japanese property cheaper in U.S. dollars, Singapore dollars or Hong Kong dollars. By our calculation, a ¥200 million property costs about US1.40 million at ¥143.31 (September 2024 average). The same property costs about 9.0% more in dollars at ¥143.31 than at ¥156.23.
• When selling or repatriating income: A stronger yen at exit means a currency gain; a weaker yen means a loss. As the table shows, rate differentials alone do not determine the exchange rate.

We do not forecast currencies. But we believe it is risky to base investment decisions on the assumption that "the BOJ is hiking, so the yen will strengthen." It is more realistic to treat the exchange rate as a third, separate variable alongside interest rates and property prices.

6. Impact by Price Segment: It Depends on Who Buys at Exit

From here on, this is our view (estimates). We believe an STR property's exit price is determined by who the next buyer is and how they fund the purchase.

In our experience: small operators now borrow at around 3.5-4%

In our experience, banks often add a spread of around 2% over market rates. With rates having risen, typical small operators now borrow for real estate at around 3.5-4%. The BOJ's average rate on new long-term loans was about 2.0% in August 2026, but that average covers all lending, including loans to large companies, individual mortgages and local governments. In our view, the terms actually offered to small operators are higher.

At this level, repayments become heavy for investors who finance 70% or more of the purchase price (in Calculation 1 below, annual repayment on ¥100 million rises from about ¥5.09 million at 2.0% to about ¥6.01 million at 3.5%). In our view, many of these investors buy for yield rather than wealth preservation, so higher rates directly change whether a deal is worth doing.

Our Calculation 1: How higher rates change what the next buyer can borrow

Banks lend only as much as the property's income can repay. The mechanism looks like this (the starting point of 2.0% is close to the BOJ's average for new long-term loans).

Figure 1. How the borrowing limit is set (assumptions for our calculation)

NOI, DSCR and equity are all assumptions. When rates rise, (3) shrinks and so does the maximum price in (4).

Figure 2. Loan rate and borrowing capacity

Each ■ = ¥5 million (our calculation). Moving from 2.0% to 3.5% cuts borrowing capacity by about 15%, and to 4.0% by about 20%.

Figure 3. Maximum price the next buyer can pay (loan + ¥20 million equity)

Each ■ = ¥5 million (our calculation). The maximum price falls by about 12-16%.

(Formula: loan amount = monthly repayment cap × {1 − (1 + monthly rate)^−300} ÷ monthly rate, where the monthly cap = ¥5 million ÷ 1.3 ÷ 12 ≈ ¥320,500. For reference, annual repayment on ¥100 million over 25 years is about ¥5.09 million at 2.0%, ¥6.01 million at 3.5% and ¥6.33 million at 4.0%.)

In segments where buyers mostly rely on loans, we believe this shrinking borrowing capacity feeds directly into the ceiling on exit prices.

Our Calculation 2: A narrower yield gap raises required yields and lowers prices

The yield gap is the difference between a property's net yield (NOI ÷ price) and the loan rate. Leveraged investors will not buy unless this gap is wide enough. If they want to keep the same gap as loan rates rise, the net yield they require goes up, and the price they can pay for the same NOI goes down.

Figure 4. Price payable for a property with ¥10 million NOI (investor requiring a 2.5-point yield gap)

Each ■ = ¥10 million (our calculation; price = NOI ÷ required net yield; the 2.5-point gap is an illustrative assumption). When the loan rate rises from 2.0% to 3.5%, the payable price falls by about 25%, from about ¥222 million to about ¥167 million.

Our Calculation 3: What a 0.25-point rise in expected yield does to price

We use the simplified formula price = NOI ÷ expected yield.

For the same rise in yield, the price declines are not very different. What makes the difference is how easily yields rise and how much NOI can grow. In our view, yields rise more readily in segments with many leveraged buyers, while in properties that can raise nightly rates, NOI growth can offset price declines. For example, 5% NOI growth almost fully offsets the roughly 4.8% price decline from a 0.25-point yield rise (our calculation: ¥10.5 million ÷ 5.25% = ¥200 million).

In our view: limited upside short term; supply and regulation decide the longer term

Based on these calculations, our view is as follows:

• In the short term, further price gains are hard to expect. Highly leveraged buyers can borrow less, and the yields they require are rising.
• Over the medium to long term, it depends on how Japanese regulation changes supply. In Tokyo, Shinjuku City published draft ordinance amendments on October 15, 2026, and is seeking public comment. The drafts would sharply limit the areas and days in which minpaku (private lodging under the Housing Accommodation Business Act) can operate and tighten standards for new ryokan licenses (permits under the Hotel Business Act). Existing minpaku would become subject to the restrictions two years after the rules take effect. If new supply is restricted, that could support the value of existing hotel-licensed properties. For background, see STR Regulatory Tightening Across Tokyo's 23 Wards: Changes from April 2022 to April 2026 and Hotel Business Act vs. Housing Accommodation Business Act.
• Projects of ¥500 million to ¥1 billion with an exit to wealthy buyers should hold up best. In our view, projects such as apartment hotels (lodging facilities with multiple guest rooms with kitchens in one building) at the ¥500 million to ¥1 billion scale, where a sale to high-net-worth individuals or companies is realistic, will hold up better in a positive-rate environment than properties aimed at small buyers. Their buyer pool is less dependent on loan terms.

7. What Cash Buyers Should Decide Now

In our view, three principles help:

• Assume a higher exit yield than your entry yield. A plan that assumes you will sell at the same yield you bought at tends to be optimistic when rates are rising. Check whether the investment still works if you set the sale price at a yield 0.25-0.5 points above your purchase yield. For more on stress-testing projections, see How Reliable Are STR Property Yield Projections?
• Choose on earning power, not on a low price. When rates rise, what supports prices is NOI growth. Location, building quality and the ability to raise nightly rates drive exit prices.
• Treat the exchange rate as a separate variable. A weak yen helps when you buy, but the exchange rate at exit is unpredictable. We recommend looking at returns in yen and in your home currency separately.

8. Conclusion: In a Japan With Positive Rates, STR Investing Becomes a Contest of Earning Power

In the negative-rate era, low borrowing costs and steadily falling expected yields pushed property prices up to a degree. With the policy rate at 1.25% and long-term yields around 3%, that tailwind has weakened, and in our view, the earning power of the property itself now matters much more.

Even for overseas investors who buy with cash, rising rates are not irrelevant. They affect returns through the borrowing conditions of future buyers and through the yen. That is why we believe it is increasingly important to choose properties that can grow income through nightly rates and occupancy and that have a credible exit to wealthy individuals or companies, rather than properties that depend on small, leveraged buyers at exit.
