Foreign investment in Japanese real estate has accelerated, but the weak yen that helped attract international buyers is becoming a more complicated part of the investment case. Japan recorded more than ¥6 trillion of commercial property transactions in 2025, setting a new annual record, while overseas investors represented roughly one-third of activity. Investment remained strong in early 2026, showing that international demand extends well beyond the currency advantage.
For foreign buyers, however, exchange rates can substantially alter both the cost of entering Japan and the eventual return. A ¥50 million property would have cost approximately $455,000 when the yen averaged around ¥110 to the dollar in 2021. At ¥150 to the dollar, the same yen price converts to about $333,000. This helps explain why Japanese assets have appeared increasingly affordable to dollar-based capital, even as domestic land prices and property values have continued to rise.
The calculation changes once an investor owns the property. Rental income, operating expenses and the eventual sale price are normally denominated in yen, meaning an unhedged foreign investor remains exposed to exchange-rate movements throughout the holding period. A strengthening yen increases the value of Japanese income and assets when converted back into dollars or euros, while further depreciation can reduce foreign-currency returns even if the property itself performs well.
This has become increasingly relevant during 2026. The yen weakened beyond ¥160 to the dollar during the year before experiencing significant reversals, while Japanese authorities intervened in the currency market. At the same time, the Bank of Japan continued moving away from the exceptionally loose monetary conditions that had defined Japan for decades, raising its policy rate to 1.25% in September. The combination of higher domestic interest rates and volatile exchange rates has made currency assumptions more important when international investors model future returns.
Foreign investors can reduce this uncertainty through currency hedging, although the impact cannot be expressed as one standard annual cost. The economics depend on the investor’s home currency, interest-rate differences, the length of the hedge and the financial instrument being used. Some investors may protect expected rental income while leaving part of the future sale value exposed to currency movements, while others may hedge a larger proportion of their investment.
Financing choices can also reduce currency mismatches. An international institution acquiring Japanese property and borrowing in yen can use yen rental income to service yen debt, creating a degree of protection against exchange-rate movements. Using dollar- or euro-denominated borrowing against an asset producing yen income creates a different risk because the cost of servicing the debt can change substantially when currencies move.
None of this means the foreign investment case for Japan is weakening. Overseas capital has been attracted by more than exchange rates. Tokyo office vacancy remains exceptionally low, rents are rising, hotels have benefited from strong visitor demand and institutional residential property continues to attract capital. Japan also remains one of Asia’s deepest and most liquid real estate markets, giving large international investors opportunities that are difficult to replicate elsewhere in the region.
The weak yen therefore represents both an opportunity and a risk rather than a simple discount on Japanese property. Investors entering Japan at favourable exchange rates could receive an additional boost if the currency strengthens during their ownership period, while renewed depreciation could offset part of the income and capital growth generated by the asset. As Japan enters a different interest-rate environment, successful cross-border investment will increasingly depend on managing two interconnected positions: the performance of the property and the currency in which that performance is earned.
