A weaker yen, and the three questions it does not answer
Reviewed
Currency movement
+8.2%
The local currency bought fewer euros at the end of this window than at the start — a cheaper entry for a euro-denominated buyer, and a worse exit for anyone already holding the asset.
What it does not show. It is not a forecast and not a property return. A currency move and a price move are different facts and routinely point opposite ways; nothing here says which way either is going next.
Foreign-buyer rules
3 of 3 published rules apply
These are the restrictions a foreign buyer meets before price is even discussed — approval regimes, surcharges, ownership limits.
What it does not show. It is not a completeness claim. A rule we have not read is not a rule that does not exist, and this row counts what is cited, not what is in force.
Cost of money
1%
The price of money to banks in this jurisdiction, which sets the floor everything else is priced from.
What it does not show. It is emphatically not a mortgage quote. What a non-resident is offered is a different number, usually much higher, and the gap between them is where a market's financing story actually lives.
Supply against absorption
Licence unconfirmed
Only one national statistics agency has been read and cleared for publication so far. For every other market the data exists and the permission to republish it does not.
Residential price cycle
119.1 against a 2015 base of 100
House prices have risen faster than consumer prices since 2015 — the market is above its own inflation-adjusted level of that year.
What it does not show. It is a position, not a direction, and it is not a valuation. Deflating by consumer prices says nothing about what the asset yields or what credit costs, and a market can sit above its 2015 level for years without that meaning anything is due.
Valuation against its own history
87.8 to income, 109.5 to rent
Housing costs less relative to incomes than it did in 2015, on this country's own index. Affordability has improved against the local salary, which can mean prices fell or that incomes rose faster — the ratio does not say which.
What it does not show. It is not comparable to another country's figure. Each index is 100 in its own 2015, so two of these side by side are two different base years wearing the same label — a market at 120 is not dearer than one at 90, it has merely moved further from its own past. It is also not a forecast, and a ratio can stay stretched for a decade.
On the market now
Not measured
No listings platform has been read for this market. The one platform this site can read covers Russian cities only, and inventing a count for anywhere else would be worse than an empty row.
Thesis
The yen has weakened materially against the euro over the last twelve months, which lowers the entry price of a Japanese asset for a buyer converting from a stronger currency. On monthly ECB reference averages the rate moved from 171.53 yen per euro in July 2025 to 185.54 in July 2026, a 8.2% weakening of the yen. Japan is also unusual among developed markets in placing no nationality-based restriction on who may own land or buildings, which is why it appears in cross-border screens far more often than a market of its size otherwise would.
Counter-thesis
A currency move is not a discount. It lowers the entry price and it lowers the exit proceeds by the same mechanism, so it only becomes a real gain if the buyer either holds yen income or expects the move to reverse. Neither is established by the exchange rate itself. The published OECD evidence adds two different 2025 Q4 checks, each for the period starting 2025-10-01, not a verdict: Japan's price-to-income index is 87.8 against its own 2015 base of 100, while its real house-price index is 119.1. The first reads prices against incomes and the second against inflation; neither is a comparable market price or proof that the currency move is a discount rather than a repricing.
The series behind those figures, and the workings
Currency

Twelve-month move in JPY per euro, 171.5313 in 2025-07 to 185.5391 in 2026-07. Positive means the local currency weakened. Source: European Central Bank monthly reference averages.

Latest daily fixing, JPY per euro on 2026-08-14. Shown because it is what a reader would see if they went and looked; the window above uses monthly averages, which one volatile day cannot move.
Against other base currencies
A market is cheap or dear relative to the capital entering it, so the same twelve months read differently depending on what the buyer holds. Both legs are quoted per euro, so the euro cancels and no third source is involved.

This is the price of money to banks, not the price of money to a non-resident buying a building. The gap between those two is where a market’s financing story actually lives, and it is not in this number. A mortgage quote for a foreign buyer depends on the lender, the asset and the borrower, and no public dataset carries it.
BIS terms permit this figure on a free page and state that nothing in their statistics constitutes investment advice. They also allow inclusion in a commercial product only where it adds no charge, so this series is published here and is not priced into any paid work.
Background
Annual national statistics from the World Bank, under a licence that permits reuse with attribution. They describe the country; they do not time an entry, and they are not counted as measurements of this market — otherwise every territory on earth would claim to be measured on the strength of one dataset.

What the rules do to a foreign buyer
Each entry cites the instrument and the authority page it was read from, with the date it was retrieved. Facts of law change; the retrieval date is how you know how old this reading is.
| Topic | In force | When it bites | Applies to | What applies | Instrument | Read on |
|---|---|---|---|---|---|---|
| Ownership by nationality | In forceNot stated by the source | On the way in | All property | Japan operates no nationality-based restriction on owning land or buildings. The one review regime that touches acquisition turns on where the property is and how large it is, not on who is buying, and it binds a Japanese buyer exactly as it binds a foreign one. | Act on the Review and Regulation of the Use of Real Estate Surrounding Important Facilities and on Remote Territorial Islands (Act No. 84 of 2021) | 2026-08-10 |
| Notification near important facilities and remote islands | In forceNot stated by the source | On the way in | All property | In a special monitored area — broadly within about 1,000 metres of a designated important facility, or on a designated remote territorial island — both seller and purchaser must notify the Prime Minister of a transfer of real estate of 200 square metres or more (for a building, 200 square metres of total floor area). Sale, gift, exchange, and assignment of an option all count, and the notification is due before the contract is concluded or within the period the rules set. | Act No. 84 of 2021, Article 13(1) and (3), with the Enforcement Order and Enforcement Regulations | 2026-08-10 |
| Withholding on rent paid to a non-resident owner | In forceNot stated by the source | While you hold it | All property | Rent paid to a non-resident owner is withheld at 20.42%. The exception is narrow: no withholding where the tenant is an individual renting the land or house for themselves or a relative to live in — so a residential let to a household is outside it, and a corporate or commercial tenant is not. A non-resident owner must also appoint a tax representative resident in Japan. | National Tax Agency, No. 12014 — Real estate income of non-residents | 2026-08-10 |
What supports this, what would make it wrong, and how it could go
What supports this
- Yen per euro moved 171.53 → 185.54 between the July 2025 and July 2026 monthly averages (ECB reference rates, +8.2% weakening).
- The latest daily fixing on 7 August 2026 was 182.64 yen per euro, so the move is not an artefact of one month's average.
- The same weakening is visible against most major currencies in the same snapshot, not only the euro, which argues against it being a euro-side effect.
- Ownership is open by nationality, verified against the Cabinet Office on 10 August 2026: the only acquisition review regime turns on location and size, not on who is buying.
What would make this wrong
- The yen recovers past its twelve-month average, removing the entry-price effect before a purchase completes.
- Japanese asking prices have already risen by more than the currency has fallen, so the local-currency price offsets the foreign-currency discount.
- Financing cost for a non-resident buyer exceeds the currency benefit over the intended hold period.
- The asset sits in a special monitored area and is 200 square metres or more, which adds a notification step for both sides before contract and can bear on timing.
- The intended use is letting to a company rather than to a household, in which case 20.42% is withheld from rent at source and the cash yield a buyer modelled gross is not the yield they receive.
Outcome branches
- The yen stays near current levels through the hold periodEntry and exit occur at similar rates, so the currency is neutral to the result and the return depends entirely on the local asset.
- The yen recovers toward its earlier level after entryThe foreign-currency return is improved by the recovery, which is the case the thesis is really about — and it is a currency view, not a property view.
- The yen weakens further after entryThe foreign-currency return is reduced even if the local-currency asset performs, which is the risk a foreign buyer takes on and should be priced deliberately.
- The property is let commercially rather than residentially20.42% withholding applies to the rent at source and a Japan-resident tax representative must be appointed, so the net yield and the administrative burden both differ from the residential case.
