What Tenants Need to Know When an Owner Change Occurs—Complete Guide to Rights, Procedures, and Precautions

What Is an Owner Change?

An "owner change" refers to the situation where an occupied rental property is sold while the tenant remains in residence—only the owner changes, not the tenant. In the real estate investment world, this is common as a "sale of income-generating property," but from a tenant's perspective, the sudden experience of "the landlord changing" can be confusing.

What matters is that an owner change is not inherently disadvantageous for the tenant. Japan's Building and Land Lease Law prioritizes tenant protection, so even when ownership changes, leasehold rights generally remain valid.

What Happens to the Tenant's Leasehold Rights?

Leasehold Rights Are Tied to the Property

If a building's leasehold rights meet the requirements of "enforcement against third parties," they can be asserted against the new owner. Specifically, if the following conditions are met, the lease agreement with the old owner will be binding on the new owner as well.

• •Receipt of the property (actual occupancy)
• •A written lease agreement in place

In typical rental agreements, the property is considered delivered from the move-in date, so the enforcement requirement is usually automatically satisfied. Even after the ownership transfer is registered with the new owner, you generally retain the right to continue living in the property under the same terms.

Rent, Security Deposits, and Special Terms Continue Under the New Owner

The terms of your lease agreement with the former owner—including rent, renewal conditions, prohibited activities, and special clauses—automatically transfer to the new owner. For example, if the contract contains a clause allowing pet ownership, that remains valid under the new owner.

However, verbal-only agreements can become disputed without written documentation, so it's important to keep important promises in writing.

Handling of Security Deposits

Security Deposits Transfer to the New Owner—But Verify

As a rule, the security deposit held by the former owner transfers to the new owner. However, you have the right to verify that it has actually been properly transferred to the new owner.

Since there are exceptional risks—such as the former owner embezzling the deposit and going bankrupt—these steps are prudent:

• •Request written confirmation from the new owner acknowledging receipt of the security deposit (¥___)
• •If a real estate agent was involved, ask them to confirm the transfer
• •If unsure, verify whether the new owner or management company is registered as a rental property manager

Properties with No Security Deposit or Using a Guarantor Company

When using a guarantor company, there often is no security deposit at all. In this case, no transfer issue arises, but you should confirm with the management company whether your agreement with the guarantor company remains valid under the new ownership.

Changes to Rent Payment Account

After an owner change, the rent payment account almost always changes. You'll receive a "payment account change notice" from the new owner or management company.

Important: Verify the Authenticity of the Notice

Scams have been reported where fraudsters impersonate management companies to request account changes. When you receive such a notice, verify its authenticity with these steps:

1. Call the former owner (or former management company) to confirm
2. Contact the new management company listed on the notice using the phone number on their official website
3. If in doubt, consider stopping payments temporarily and consulting a lawyer

Until you receive official confirmation, you can continue paying into the old account and settle the difference later—this is acceptable.

Your Rights If Asked to Vacate

The New Owner Generally Cannot Force You to Vacate

There is no legal basis for a request to vacate simply because the owner bought the property. Article 28 of the Building and Land Lease Law requires "just cause" for a landlord to refuse renewal or terminate a lease, and eviction cannot be forced without concrete circumstances such as "building deterioration" or "the owner's personal use necessity."

Negotiating Relocation Assistance

If the new owner insists on your vacating, relocation assistance (moving costs and compensation) becomes a condition. The typical amount ranges from several months to several years' worth of rent, but varies significantly depending on individual circumstances.

If asked to vacate, it's best to consult a lawyer or Houterasu (the Legal Services Center) before complying. Free legal consultation services allow you to receive expert advice without cost.

Changes to Renewal and Termination Conditions

A new owner may request to convert to a fixed-term lease or raise the rent. These changes cannot be imposed unilaterally without the tenant's agreement.

However, when renewing after the lease period ends, the new owner's intentions may come into play. If renewal terms don't align, this may lead you to consider moving to another property.

Summary: Staying Calm Through an Owner Change

An owner change may come suddenly to a tenant, but you are legally protected. Keeping these points in mind will help you avoid unfair treatment:

• •Your leasehold rights are generally preserved, and you can continue living under the same terms
• •Security deposits transfer to the new owner, but request written confirmation
• •Always verify the authenticity of payment account change notices
• •Eviction requires just cause; you are not obligated to comply with unjustified requests
• •For questions or concerns, consult a lawyer or Houterasu early

Keep this knowledge handy for peace of mind in your living situation.

Even if a rental property owner passes away, the rental lease agreement is automatically transferred to the heirs and the tenant's rights are protected. This guide explains how to handle changes to rent payment destinations, deposit procedures when multiple heirs exist, and how to respond to requests for contract modifications from the new owner.
