Choose a property consultant in Japan

Choosing a property consultant in Japan is not one choice; it is a sequence of choices about scope, licences, conflicts, evidence standards, fees and professional responsibility. What follows is a method for making those choices and a checklist for keeping an auditable trail. It does not replace regulated advice; it tells you which regulated professional to ask which question.

Match the question to the professional who is authorised to answer it

Before contacting anyone, write down what you actually need. Japanese real-estate records are fragmented across multiple local Legal Affairs Bureaus, municipal planning departments and archived corporate registries. There is no single national portal for private use, so the type of professional you need depends entirely on the question you are trying to answer.

• If you need to verify ownership, mortgages or easements, the authoritative record is the land register (登記簿) held at the local Legal Affairs Bureau (法務局). A judicial scrivener (司法書士) is authorised to prepare and file registration applications.
• If you need a boundary survey or a cadastral map correction, the authorised professional is a land and building surveyor (土地家屋調査士), not a general agent.
• If you need a formal valuation for financing or litigation, a regulated real-estate appraiser (不動産鑑定士) must produce the report.
• If you need to confirm planning permission, zoning or building-code compliance, the relevant authority is the local government planning department (市町村都市計画課), not a private consultant.
• If you need legal advice on lease protection, eviction or compensation, a judicial scrivener (司法書士) or a lawyer (弁護士) is the appropriate professional; a general property consultant cannot give that advice.

The decision rule: match the question to the professional who is authorised to answer it, then keep the written record of which registry or authority produced each fact.

What a property consultant can and cannot do

A property consultant in Japan assembles and interprets records. They are not a substitute for the professionals who hold the legal mandate for specific tasks.

Task	Authorised professional	Why
Boundary surveys and registry map corrections	Land and Building Surveyor (土地家屋調査士)	Only this licence can prepare boundary surveys and file cadastral corrections.
Preparing and filing registration applications	Judicial Scrivener (司法書士)	Authorised to handle court and registry filings for property.
Formal valuation for financing or litigation	Real-Estate Appraiser (不動産鑑定士)	Only regulated appraisers can issue official valuation reports.
Legal disputes, lease terms, eviction notices	Attorney (弁護士)	Only a lawyer can represent you in court or give formal legal opinions.
Buying or selling as an agent	Regulated real-estate agent (宅地建物取引士)	Required by law to handle sales, leases and brokerage.

Start with the choice you are making

Before you contact anyone, write down the single choice you need the consultant to support. The same records serve different purposes, and the consultant who is right for one choice may be wrong for another.

Your situation	Primary record set	Lead professional
Buying a property for redevelopment	Land register, cadastral map, urban planning map, building confirmation file	Land and Building Surveyor (土地家屋調査士) + regulated agent
Renovating or rebuilding an existing structure	Building confirmation application, building standards file, seismic records	Architect with a building permit track record
Tenant relocation or demolition (借家 / 立退き)	Lease contract, notice history, redevelopment plan documents	Lawyer (弁護士) + regulated real-estate agent
Inherited or vacant property	Koseki (family registry), land register, fixed-asset tax records	Judicial scrivener (司法書士)
Boundary or area disputes	Cadastral map, survey records	Land and Building Surveyor (土地家屋調査士)
Valuation for financing or tax	Appraisal reports, JREI statistics	Regulated real-estate appraiser (不動産鑑定士)
GIS / urban planning analysis	National Land Numerical Information, zoning maps	Local government planning department

Verify the licence before you share details

Ask for the consultant’s licence number and check it against the relevant professional association’s public registry. A legitimate professional will provide this without hesitation. If a consultant claims to cover tasks that legally require a different licence, treat that as a red flag.

Check for conflicts in writing

Ask the consultant to disclose, in writing, any relationship with a seller, developer, lender or referring agent. A simple question works: “Please list every party connected to this property who is paying you or has paid you in the past 12 months.” Keep the answer in your file.

Set the evidence standard early

Agree on what counts as a verified fact. For every key claim (ownership, boundary, zoning, building-code status), ask for the source document, its date and the office that issued it. A consultant who cannot name the source registry for a claim is giving you an opinion, not a verified fact.

Separate fees from responsibility

Before work starts, get a written scope-of-work statement that names which tasks the consultant will perform and, just as importantly, which tasks must be performed by another authorised professional. A consultant who cannot draw that line is a liability.

Keep an auditable trail

Use a simple checklist for every property you investigate. For each fact, record:

• The question you needed to answer
• The record or registry consulted
• The date of the record
• The office that issued it
• The professional who interpreted it
• The licence number of that professional

This turns a stack of reports into a file you can hand to a lawyer, an appraiser or a future buyer without starting over.
