What REITs are, Japanese vs global, interest-rate sensitivity, leverage and property risk, and their portfolio role.
REITs are listed trusts that own income-producing property; they offer property exposure and income but behave with equity-like volatility and are sensitive to interest rates and leverage — a satellite holding, not a substitute for safe bonds.
A REIT (Real Estate Investment Trust, 不動産投資信託) is a listed or unlisted trust that owns and operates income-producing property — offices, retail, logistics, residential, or hotels — and passes rental income to investors. Because they trade on an exchange (for J-REITs) or via funds, they give property exposure without the cost and illiquidity of buying a building directly.
You can hold REITs through individual listed J-REITs, a broad J-REIT ETF, or a REIT fund (Japanese or global). A global REIT fund adds foreign property and, being unhedged, foreign-currency exposure on top of the property risk.
REITs are notably sensitive to interest rates. Because they rely on borrowing and their income is valued against prevailing yields, rising interest rates often pressure REIT prices, while falling rates can support them. This rate link means REITs can fall even when broad equities are steady, and vice versa.
They also use leverage (borrowing to buy property) and can be concentrated in specific property sectors, both of which amplify risk. In practice REITs display equity-like volatility and can suffer large drawdowns. They are income-oriented, but that income comes with real capital risk.
A common mistake is treating REITs as a safe, bond-like income source. They are not: their equity-like volatility and rate sensitivity make them a growth/income asset, not a stability anchor. If your goal is to reduce portfolio volatility or match yen liabilities, safe bonds or cash do that job; REITs do not replace them.
Used deliberately, a modest REIT allocation can add diversification (property returns are not identical to broad equities) and income to a portfolio. Size it as a satellite, understand the rate and leverage risks, and check NISA eligibility and dividend receipt method if you hold them there.

This is education, not a recommendation. Most beginners research low-cost, broadly diversified index funds — for example all-country (全世界株式) or S&P 500 trackers — rather than picking individual stocks, because low fees and diversification are within your control while returns are not. Understand that values fall as well as rise, match the risk to your time horizon, and never invest money you may need soon.
