Buying Property in Japan? Start With the Project, Not the Property

Are you really ready to purchase a property?

When funds are in place, information has been gathered from property portals, SNS, or YouTube, and candidate properties have been shortlisted, many people believe they are “ready to purchase.”

However, this is not “preparation for making the project a success.” In many cases, without thorough, fundamental consideration, people skip the upstream planning stage and jump straight into the downstream phase of searching for and purchasing a property.

The Difference Between Property DD and Project DD

In real estate transactions, property due diligence (Property DD)—which involves investigating ownership rights, boundaries, building conditions, infrastructure, and legal restrictions—is undeniably important.

However, when a property is intended to achieve a specific objective (such as a business venture, a second home, or relocation), what must precede Property DD is Project Due Diligence (Project DD).

  • The question posed by Property DD: “Are there any legal issues or physical defects with this property?”

  • The question posed by Project DD: “Can your objective actually be achieved in this location, under these conditions, with this budget, and through this operational structure?”

 

Purchasing a property is not the ultimate goal of a project; it is merely one step in the process. Proceeding without performing Project DD to ensure the objective can be achieved carries significant risk.

The Danger of Relying on Online “Checklists of Things to Watch Out For”

Information such as “checklists of things to watch out for upon purchase” or “key points for moving to the countryside or buying a kominka” overflows across the internet and SNS. You may have seen typical tasks compiled into lists, such as checking local community rules, locating garbage collection points, or following procedures for greeting neighbors.

 

However, reading such superficial lists and assuming, “as long as I go through these items one by one, everything will be fine,” is in itself extremely dangerous.

General lists and task compilations are merely averaged examples from past cases. Project DD is not an exercise in filling out predefined checklists; it is a process that includes designing from scratch the very approach of “what to investigate, with whom, and how,” tailored to your project’s objective, location, and specific property conditions. Universal lists serve as nothing more than reference points.

Approaches Vary Completely Depending on the Project

The required information and investigation methods vary completely depending on the objective and location.

  • In the case of a kominka in the countryside or heavy snowfall regions:

    In addition to inquiring at municipal offices, directly interviewing local communities and residents—and gaining an accurate understanding of reality through down-to-earth dialogue (such as snow removal rules, actual infrastructure maintenance costs, and the local community's receptivity)—is essential. There is a vast amount of information that can only be obtained by physically visiting the site and building relationships.

  • In the case of business use or a second home in an urban area:

    Rather than approaching local residents, verification focuses primarily on operational aspects through inquiries with private businesses, management companies, and contractors—evaluating the scope of services provided, verifying legal requirements such as changes of building use, and estimating realistic operational costs.

    The importance of the local community and relationships with neighbors is not as pronounced as in the countryside, and conditions differ between highly fluid areas with many rental properties and traditional commercial or downtown districts.

 

In this way, determining the approach itself—“where, to whom, what, and how to inquire”—is a crucial component of Project DD.

Another Bias in Perspective: “Overseas Expatriate Communities”

Many buyers from overseas tend to place strong trust in overseas communities, forums, and experiences shared by fellow expatriates on SNS. Information exchange within a community that shares a common language and background offers a sense of security and often yields valuable insights. Indeed, things that are obvious to Japanese people may not be obvious to people overseas, so belonging to a community and gathering information from that perspective certainly has value.

 

However, heavily relying solely on information contained within such communities carries structural risks. This is because information tends to be biased toward a “viewpoint from overseas,” leaving out the perspective of “how the Japanese side, the local community, and local contractors perceive the situation.”

  • Disconnection from the local community: Proceeding while ignoring local rules and context creates underlying friction, leading to future conflicts.

  • Collapse of a realistic operational structure: Poor communication with local contractors and management companies prevents the project from functioning after the purchase.

  • Indifference to potential risks: Swallowing personal “success stories” within the community leaves one defenseless against underlying risks unique to Japanese systems and local structures.

 

No matter how much information is exchanged within a community, it remains merely a view of the world seen from the outside. A real project functions strictly within the reality of Japanese legal systems, local municipalities, and the local community on the ground.

The Ultimate Question: “How Are You Going to Execute That DD?”

At this point, you need to ask yourself about your own plan:

“In your project, are you able to specifically determine the approach—where, to whom, what, and how to verify?”

Knowing from books or online lists that “greetings are necessary” or “local community rules should be checked” is entirely different from being able to judge and execute “with whom, in what context to verify, and how to evaluate risks based on the results” in your own specific project.

Furthermore, even if you determine the right approach, the question remains: “Who will execute that DD on-site in a foreign country (Japan) where you have no actual residence?” No project can be completed solely through remote investigations, online research, or internet information.

 

Particularly in the countryside or with a kominka, attempting to complete the process remotely or minimize site visits is almost always an inefficient and high-risk approach.

Starting a property search without even designing the investigation approach means carrying the risk of making decisions without verifying feasibility.

Pausing Before Searching for a Property

Preparation for purchasing real estate is not simply about securing funds and searching property portal sites. There is an essential “upstream process” that must be conducted for any project.
At the core of this upstream process lies Project DD, which objectively verifies the overall feasibility of the project.
Before jumping into the property search and purchase phase, pausing to ask yourself whether you are truly ready—and if so, what objective evidence supports that readiness—is extremely critical from a risk management perspective.
