One of the most common questions we receive is: “Do overseas investors really continue buying properties in Japan?” For those standing on the outside of the market, the process can seem like a one-time endeavor or a singular “passion project.” However, our experience at Sumica says a definitive yes. Read on to learn why many buyers are interested about scaling akiya investment.
The First Property as a Proof of Concept

Many of our clients begin their journey by investing in a single property to understand how the process works. This initial acquisition serves as a critical proof of concept. It allows the investor to move past theoretical research and see the tangible results of a renovation, feel the reality of local rental demand, and experience our property management systems firsthand.
Once they see the system move from a plan to a performing asset, they gain the confidence needed for scaling akiya investment. It is at this stage that the focus shifts from simply “buying a house” to building a sustainable, long-term portfolio.
Moving Toward Repeatable Execution

It is not unusual for an investor to acquire multiple houses over time. In fact, once the first project is stabilized and the initial “learning curve” is behind them, many of our clients move significantly faster. It is quite common for investors to plan and execute several purchases within the same calendar year once they trust the execution phase.
When you are scaling akiya investment, you aren’t just buying more real estate; you are leveraging a proven system. Because the foundational legal structures, tax registrations, and banking relationships are often established during the first purchase, subsequent acquisitions come with much less administrative friction. This allows the investor to focus on asset selection and growth rather than paperwork.
Why the Repeat Model is Our Strongest Proof

For us, this high rate of repeat investment is the strongest proof that the model works. Investors return because the results are transparent and the process is predictable. By expanding into multiple properties, investors can diversify across different neighborhoods or even prefectures, reducing regional risk and creating a more balanced asset base.
Ultimately, the goal for many of our investors isn’t just to own a single home. It is to create a reliable, long-term presence in the Japanese market. Through scaling akiya investment, overseas buyers can turn a single learning investment into a professional and diversified property portfolio.
