A listing shows the house. The documents define the purchase.
A listing can make a property look simple: one house, one plot of land, one price.
The documents may tell a more complicated story. They can show who legally owns the property, which land and buildings are included, what rights affect them, and what restrictions or disclosures need your attention.
You do not need to become an expert in Japanese real estate paperwork. Before signing, though, you should understand what the key documents say and know when an answer needs further investigation.
This guide explains the main documents foreign buyers are likely to encounter, what to look for, and the practical questions to ask.
Before looking at individual documents, it helps to understand why property paperwork can be harder to read than a listing. The difficulty is rarely one unfamiliar term. It is the need to compare several records with the house itself and with the way you plan to use it.
Before you begin
What this guide covers, and why the documents can feel difficult
Japanese property documents can be difficult for foreign buyers because they combine unfamiliar legal terms, separate records, and questions that paperwork alone cannot answer.
Common challenges
1
The documents use legal and real estate terms that may be unfamiliar, even in translation.
2
A listing may describe a home as one property, while the records separate land parcels, buildings, access rights, and other interests.
3
Older homes do not always match the records exactly because of past additions, boundary questions, or incomplete documentation.
4
A document can confirm what is registered without confirming the current physical condition of the house.
5
The effect of a restriction depends on whether you plan to use the property as a vacation home, renovate it, live there full-time, or rent it out.
This guide covers documents related to ownership, land, buildings, access, infrastructure, disclosures, and the terms of the purchase. It does not replace property inspection, legal advice, tax advice, or transaction-specific review by the licensed professionals involved.
The aim is simpler than mastering every document: know what each record is for, what questions it can answer, and when an unclear answer is a reason to pause before signing.
Start with ownership. Before comparing the property's condition, boundaries, or renovation potential, confirm who is registered as the owner and whether the seller can complete the transaction.
Document 1
Registry certificate: Who legally owns the property?
The registry certificate, or 登記事項証明書 (toki jiko shomeisho), is the official record for land or a building. It records registered information about the property, including ownership and certain registered rights.
For buyers, the first question is straightforward: does the registered owner match the person with authority to sell the property?
Check the record
✓The registered owner's name and address
✓The land or building described in the record
✓Registered area and building details
✓Mortgages, liens, or other registered rights
✓Names, addresses, or entries that need an explanation
A mismatch does not automatically mean the sale cannot proceed. An owner may have inherited the property, or a registration may need to be updated. The point is to understand the situation before you commit.
Ask before signing
□Who is the registered owner?
□Does the seller have authority to sell the property?
□Are there mortgages, liens, or other rights registered against it?
□Does anything need to be removed, corrected, or updated before closing?
Once the ownership position is clear, turn to the land itself. A house may look like it sits on one simple plot, but the sale can involve several parcels, a separate access strip, or land that is not included.
Document 2
Cadastral map: Which land is actually included?
The cadastral map, or 公図 (kozu), is an official map or drawing used for land registration purposes. It helps identify parcel numbers and shows how a parcel relates to neighboring land.
It helps answer a question that listing photos often cannot: which land is included in the sale?
Compare the map with the listing
✓The parcel number or numbers included in the sale
✓The position and shape of each parcel
✓Neighboring parcels
✓Narrow strips of land, access areas, or separate-looking plots
✓Anything that does not appear to match the listing or your viewing
The garden, driveway, access strip, or open land around a house is not necessarily part of the property being sold. A house may use land that belongs to someone else, or access may depend on separate rights.
Ask before signing
□Which parcel numbers are included in the sale?
□Does the land in the listing match those parcels?
□Is any land used by the house excluded from the transaction?
□Are there rights or agreements affecting access or use of neighboring land?
Identifying the parcels is only part of the picture. You also need to know whether the recorded land area and boundaries are clear, especially when a garden, driveway, or open area appears to run into neighboring land.
Document 3
Land survey drawing: How large is the land, and are the boundaries clear?
A land survey drawing, or 地積測量図 (chiseki sokuryozu), may show measurements, boundary points, and the documented shape of a parcel. Not every property has one, especially older rural properties.
Its presence can help clarify the size and boundaries of the land. Its absence does not automatically make a property unsuitable, but it changes what still needs to be confirmed.
Check the boundaries
✓The registered land area
✓Boundary points and measurements
✓The date and basis of the survey, where shown
✓Differences between the drawing, registry, listing, and physical site
✓Land that appears connected to the property but is not included
Imagine a buyer who sees a large garden beside an older house. If part of that garden belongs to a neighboring parcel, the usable property may be smaller than it first appears. The question is whether the buyer will own it and can use it as intended.
Ask before signing
□Are the boundaries confirmed?
□Has a boundary survey been completed?
□Does the documented land area match the advertised area?
□Is any part of the visible site excluded from the sale?
□Is there a known boundary dispute or an unresolved question with a neighbor?

The land records tell you what surrounds the house. Building records help answer a different question: does the registered building match the structure you are actually considering buying?
Document 4
Building drawings and floor plans: What building is registered?
Building drawings, or 建物図面 (tatemono zumen), and floor plans, or 各階平面図 (kakukai heimenzu), can show the registered location, floor areas, number of floors, and other details about a building.
These records are available through the Legal Affairs Bureau where they have been filed. For older homes, they help you compare the registered building with the one that exists today.
Compare records with the house
✓Registered building area
✓Number of floors
✓Floor plans or floor areas, where available
✓Construction details recorded in the registry
✓Additions, enclosed spaces, or extensions that do not appear in the documents
Akiya are often altered over decades. A former porch may have been enclosed, an extension may have been added, or interior spaces may have changed. A difference does not tell you whether the work is acceptable, compliant, or a problem for your plans. It means the difference needs a clear explanation.
Ask before signing
□Does the registered building reasonably match the building on site?
□Are there additions or extensions that are not reflected in the records?
□Does the documented floor area match the listing?
□Do any differences affect renovation, insurance, financing, or rebuilding plans?
Ownership, land, and building records establish the basic shape of the purchase. The next document brings together restrictions, access, infrastructure, and other disclosures that may affect what you can do with the property.
Document 5
Explanation of Important Matters: What restrictions and risks are being disclosed?
The Explanation of Important Matters, or 重要事項説明書 (juyo jiko setsumeisho), is one of the central documents in a Japanese property transaction. It explains important information that may affect the property or the deal.
The exact contents vary by property, but the document can cover legal restrictions, roads, infrastructure, hazard information, rights affecting the property, and other matters that affect ownership or use.
Review what applies
✓Land-use and building restrictions
✓Road and access information
✓Rebuilding limitations
✓Water, sewer, gas, and other infrastructure details
✓Hazard-related information
✓Rights or agreements affecting the property
✓Items marked as applicable or requiring further explanation
Do not sign this document simply because it is standard paperwork. If an item is unclear, ask what it means for your plans. The answer may differ for a vacation home, a full-time residence, a renovation project, or a rental property.
Ask before signing
□Can you explain each item that applies to this property?
□Are there restrictions that affect renovation, rebuilding, or intended use?
□Are there road or access issues?
□What hazard information has been disclosed, and what should I verify independently?
□Is there anything here that needs further investigation before I sign?
The disclosure documents help you understand the property and its known restrictions. The contract answers a separate question: what has the buyer and seller actually agreed to, and on what terms?
Document 6
Purchase and sale contract: What are you agreeing to buy?
The purchase and sale contract, or 売買契約書 (baibai keiyakusho), sets out the terms agreed by the buyer and seller, including price, payment, handover, responsibilities, and special conditions.
The listing describes a property. The contract defines the deal.
Review the agreed terms
✓Purchase price and payment schedule
✓Earnest money deposit and other payment conditions
✓Handover date and handover condition
✓Land, buildings, fixtures, and other items included in the sale
✓Costs assigned to the buyer or seller
✓Special conditions
✓Cancellation and default provisions
✓Clauses concerning the property's condition or defects
If something important was discussed verbally, do not assume it is covered. Ask where it appears in the transaction documents and how it will be handled.
Ask before signing
□What exactly is included in the sale?
□Which costs am I responsible for?
□What happens if a problem is found before closing?
□What are the conditions for cancellation or default?
□Does any contract term differ from what I was told earlier?
□Which clauses need a more detailed explanation before I sign?
A contract can state what is included, but it does not make a practical access issue disappear. Road status, ownership, and rights to use a private lane can affect daily use, renovation work, and future rebuilding plans.
Document 7
Road and access documents: Can you legally reach and use the property?
A driveway or lane can look perfectly usable while the legal position is more complicated. Road and access records help establish how a property connects to a road, who owns that road, and what rights apply.
Access affects more than day-to-day convenience. It can affect vehicle entry, construction work, future rebuilding, and the use of the property over time.
Confirm the access position
✓Whether the road is public or private
✓Road width and physical access
✓Shared access arrangements
✓Ownership of access land
✓Rights to use private roads or neighboring land
✓Issues that could affect rebuilding
Ask before signing
□What is the property's legal road access?
□Who owns the road or access strip?
□Do I have a documented right to use it?
□Are there shared maintenance obligations or fees?
□Could the current house be rebuilt if it were demolished?
Access gets you to the house. Infrastructure determines how the house functions once you are there. Records can describe the water, wastewater, gas, and utility arrangements, but the current condition of those systems still needs separate confirmation.
Document 8
Infrastructure records: What actually serves the house?
Infrastructure records can help show how the property receives water, handles wastewater, and connects to gas, electricity, and other services.
A house may have a bathroom, kitchen, pipes, and electricity without being ready for comfortable year-round use. Older systems may need repair, upgrading, or closer inspection.
Confirm the services
✓Public water supply or private well
✓Public sewer connection or septic system
✓Gas supply
✓Private or shared infrastructure
✓Connection arrangements
✓Ongoing maintenance duties and fees
A septic system is an on-site wastewater treatment system rather than a connection to the public sewer network. It may require regular maintenance, and its condition should be confirmed separately.
Ask before signing
□Which utilities are connected and working now?
□Is the water supply public or private?
□Is wastewater handled by public sewer or septic?
□Who maintains private or shared infrastructure?
□Are there connection, repair, inspection, or maintenance costs to budget for?
What the documents cannot tell you
Documents are useful, but they are not a substitute for inspecting the house. They help establish the recorded and contractual picture. They cannot confirm every physical or practical issue that may affect your decision.
Documents can help you understand
Documents cannot reliably tell you
Who owns the property
Whether the roof leaks
Which land and buildings are registered
Whether floors are soft, uneven, or structurally sound
Documented water, wastewater, gas, and other infrastructure arrangements
Whether concealed timber has termite damage or moisture problems
Important matters disclosed in the transaction
Whether plumbing, heating, electrical systems, or septic systems are in good working condition
Documented rights, restrictions, and access arrangements
Whether a repair or renovation budget is realistic
The terms you are being asked to accept
Whether the neighborhood suits the way you plan to live
You need both sides of the picture: the legal record and the physical property. If the documents say one thing and the property appears to say another, pause and ask why before moving forward.
Each document answers part of the buyer's question. Before signing, step back and check whether the ownership records, land and building details, physical condition, disclosures, and contract terms all describe the same purchase.
Final review
Before you sign: a practical document checklist
Before committing to a purchase, make sure you can answer these questions. Treat this as a final-pass reference, not a substitute for transaction-specific advice from the licensed professionals involved.
Ownership and what is included
□Does the registered owner match the seller, or is there a clear explanation and a documented path to resolve the difference?
□Does the seller have the authority needed to complete the sale?
□Which land parcels are included in the sale?
□Which buildings, fixtures, equipment, access strips, gardens, parking areas, or other items are included?
□Is anything you assumed was part of the property actually excluded?
Land, buildings, and boundaries
□Do the parcel numbers, land area, and building details match the listing and the property you viewed?
□Does the registered building reasonably match what exists on site?
□Are there additions, enclosed spaces, or other changes that are not reflected in the records?
□Are the boundaries confirmed, or is there an unresolved question with a neighbor?
□Does any visible garden, driveway, or open land belong to a separate parcel or another owner?
Rights, access, and restrictions
□Are there mortgages, liens, leases, easements, or other registered rights affecting the property?
□Does the property have legally usable road access?
□Who owns any private road or access strip, and do you have a documented right to use it?
□Are there shared maintenance obligations, fees, or agreements?
□Do any restrictions affect your plans to renovate, rebuild, live in the property, rent it out, or leave it vacant for part of the year?
Utilities and physical condition
□What water, wastewater, gas, electricity, and other systems serve the house?
□Are those systems connected and operating now?
□Is wastewater handled by public sewer or a septic system, and who is responsible for maintenance?
□Have you confirmed the physical condition of the roof, structure, floors, drainage, plumbing, heating, electrical system, and other parts that matter for your intended use?
□Does the likely repair and renovation budget fit your overall plan?
Disclosures and contract terms
□Do you understand each applicable item in the Explanation of Important Matters?
□Have you reviewed hazard information and considered what it means for the property and your intended use?
□Does the purchase and sale contract state the correct price, payment schedule, handover date, and handover condition?
□Does the contract clearly state which costs are paid by the buyer and seller?
□Are verbal promises, repair agreements, included items, or special conditions written into the transaction documents?
□Do you understand the clauses covering cancellation, default, defects, and problems discovered before closing?
Final decision
□Does the legal record, physical property, and contract describe the same purchase?
□Which questions remain unanswered?
□Has the appropriate licensed professional explained any issue that could affect your decision?
The paperwork should make the purchase clearer
You do not need to understand every Japanese term before you begin looking at homes. Before signing, though, you should understand what you are buying, who owns it, what affects its use, and what remains uncertain.
A document you do not understand is not automatically a problem. A document that nobody can explain is a reason to pause.
The goal is simple: the legal record, the physical property, and the deal in front of you should describe the same purchase.
If you already have a property in mind, the next useful step is to review the documents alongside the listing, the physical condition of the house, and your intended use. AkiyaHub can help buyers identify the questions that need answers before they spend serious money.
