The yen lost roughly a third of its value against the US dollar between 2021 and 2024. For you, the foreign buyer looking at a Tokyo condo, that is not a headline. That is your entry price.
This article breaks down what the weak yen actually changed — and what it did not. We will look at the discount you are really getting, the risks hiding inside that discount, and how to think about exit timing when your home currency and the asset currency move on different clocks.
The headline discount is real, but smaller than it looks
In January 2021, USD/JPY traded near 103. By mid-2024 it pushed past 160. As of late 2025 it sits in the 150s. For a dollar-based buyer, a ¥100M condo that cost about USD 970,000 in early 2021 now costs closer to USD 660,000 at 150.
That looks like a 32% discount. It is not.
Tokyo 23-ward new condo prices rose sharply over the same period. According to the Real Estate Economic Institute (不動産経済研究所), the average new condo price in the 23 wards crossed ¥100M in 2023 and stayed elevated through 2024–2025. Used condo prices in central wards followed a similar tendency, with Minato (港区), Chiyoda (千代田区), and Shibuya (渋谷区) leading.
So the math you actually face:
- JPY price: up roughly 30–40% in central Tokyo since 2021
- JPY-to-USD conversion: down roughly 30%
- Net effect for a USD buyer: closer to flat, or a modest discount, depending on the ward and the building
For a EUR buyer the story is similar. For buyers in SGD, HKD, or USD-pegged currencies, the same. For buyers in CNY or KRW the discount is more muted because those currencies also softened against USD.
The headline "Japan is cheap" narrative is half-true. The cheapness is relative to old yen levels, not to current Tokyo JPY prices.
What the weak yen actually changed in buyer behavior
You are not the only one doing this math. The flow data shows it.
The Land Institute of Japan (土地総合研究所) and brokerage reports from 2023–2024 both indicate a sharp rise in foreign cash purchases in central Tokyo, particularly in:
- Minato (港区) — Azabu, Roppongi, Shirokane
- Chuo (中央区) — Nihonbashi, Tsukiji waterfront
- Shibuya (渋谷区) — Hiroo, Ebisu
- Chiyoda (千代田区) — Banchō, Kojimachi
This is not just individual buyers. It is family offices, Asian holding companies, and a growing pool of returning Japanese expatriates paid in foreign currency. The result is a tendency toward price stickiness at the top of the market, even when domestic demand softens.
For you, this means two things:
- In prime wards, you are competing against other FX-advantaged buyers. The "discount" is partly arbitraged away.
- In non-prime wards, the FX advantage is more intact but you take on the underlying risk of a thinner resale market.
The hidden cost: you are long a JPY asset
Buying a Tokyo condo with USD or EUR is not just a real estate trade. It is a currency trade layered on top of a real estate trade.
If you hold the condo for 7 years and the yen strengthens back to 120, your JPY-denominated asset gains roughly 20% in your home currency before any price movement. If the yen weakens further to 170, you lose 12% in your home currency before any price movement.
Most foreign buyers we speak with at RE : public underestimate this. They think in JPY when buying and in their home currency when selling. That is an inconsistent frame.
Three points to internalize:
- Your rental yield is in JPY. If you live abroad and remit, FX eats or adds to your real yield every month.
- Your mortgage, if any, is likely in JPY. That is actually a natural hedge — your debt and asset move together.
- Your exit will be in JPY. Unless you sell to another foreign buyer pricing in your currency, you convert at the rate on that day.
The analysis result we keep arriving at: if you cannot tolerate a 20% adverse FX swing over your holding period, the Tokyo condo math does not work as a pure investment. It works as a use-asset (you live in it, or your family does) or as a long-horizon hold where you accept FX as noise.
Where the reference estimates are getting distorted
Comparable-sales analysis in Tokyo is normally straightforward. The Real Estate Information Network System (REINS, 不動産流通標準情報システム) and public transaction data from the Ministry of Land, Infrastructure, Transport and Tourism (国土交通省) give you a reasonable base.
The weak yen has introduced two distortions you should know about:
1. Foreign-buyer premium on certain buildings
Some buildings in Azabudai, Toranomon, and the Bay area have transacted at prices that do not reconcile with their per-tsubo (坪) reference range based on local comps. The premium reflects:
- English-speaking building management
- Concierge services priced for international residents
- Branded residences (Aman, Janu, Bulgari, etc.)
If you pay this premium, understand that your future buyer pool is narrower. Resale liquidity depends on the FX environment continuing to favor foreign buyers. That is a risk, not a given.
2. Cash-buyer compression of negotiation room
In a normal market, a Tokyo seller might accept 3–7% off asking. In foreign-cash-heavy submarkets in 2023–2024, that negotiation room compressed toward 0–2%. Sellers know cash buyers are time-sensitive and FX-motivated.
When we run a second-opinion analysis for a client at RE : public, we flag listings where the asking price already prices in foreign demand. You may still buy. But you should buy with eyes open.
How to think about your purchase price now
Here is the framework we suggest:
Step 1: Strip out the FX illusion. Look at the JPY asking price. Compare it to JPY comps from 2019–2020. Is the building up 10%, 30%, 50%? That tells you the real estate move, separate from currency.
Step 2: Stress-test the FX path. Run three scenarios for your holding period:
- Yen stays at 150
- Yen strengthens to 120
- Yen weakens to 170
If your decision flips between scenarios, you are FX-betting, not property-buying.
Step 3: Check the building, not just the ward. Two condos on the same street can have very different tendencies. Land-share ratio (敷地権割合), management association health, repair reserve fund (修繕積立金) balance, and earthquake standard (新耐震 vs. 旧耐震) matter more than the postal code.
Step 4: Get a second opinion on the number. The agent showing you the property earns commission from the transaction closing. That is structural, not a moral problem. But it means their reference estimate is not neutral. You want an independent analysis result before you sign.
What foreign buyers consistently get wrong
From the cases we see, the recurring mistakes:
- Treating the FX discount as permanent. It is not. Currency mean-reverts on long horizons.
- Skipping the management association documents. The 重要事項調査報告書 tells you the building's financial health. If the repair reserve is underfunded, you inherit that risk.
- Underestimating ongoing JPY costs. Management fees (管理費), repair reserves (修繕積立金), property tax (固定資産税), and any rental management fees are JPY-denominated and recur monthly or annually. The weak yen makes the purchase cheap. It does not make the holding cheap.
- Buying tax-inefficiently. Non-resident foreign owners face withholding on rental income and capital gains. The structure (personal name, GK, overseas entity) has tax consequences that should be modeled before, not after, purchase.
- Assuming Tokyo equals Japan. Osaka, Fukuoka, Sapporo, and Naha have very different supply-demand curves. The yen discount is uniform; the underlying market is not.
A practical checklist before you offer
- You have the JPY price history of the building or comparable units, not just the current asking.
- You have read the 重要事項調査報告書 and the long-term repair plan (長期修繕計画).
- You have modeled three FX scenarios for your exit.
- You have confirmed the building meets the post-1981 earthquake standard (新耐震基準), or you understand the implications if it does not.
- You have checked the land-share ratio against comparable buildings.
- You have a tax structure in mind, reviewed by a Japanese tax professional (税理士).
- You have an independent reference estimate from someone who does not earn commission on the deal.
The bigger picture
The weak yen reshaped the math, but the fundamentals of Japanese condo ownership did not change. Buildings still age. Repair reserves still need to compound. Tokyo's population is still concentrated in a handful of wards. Earthquake risk is still real and pricing-relevant.
What did change is the buyer pool. A larger share of central Tokyo transactions now involves cross-border money. That is a structural shift, and it cuts both ways: it supports prices in prime areas, and it makes those same prices more sensitive to a yen reversal.
If you are buying to live in Tokyo, the FX question matters less. You consume the use-value in JPY, and the math is straightforward.
If you are buying as an investment, you are taking three positions at once: Tokyo real estate, JPY currency, and the specific building. Each deserves its own analysis.
This is not investment advice. The final decision is yours.
