Sublease and Master Lease Contracts: What They Are

A sublease is a rental contract in which a real estate company (sublease or master lease company) leases a building in bulk from the property owner and then subleases it to tenants.

Standard: Property owner (lessor) → Real estate broker (intermediary) → Tenant (lessee) Sublease: Property owner → Sublease company (sublessor) → Tenant (actual lessee)

Master Leases and Subleases: What Foreign Renters Need to Know About Management Systems and Contract Structure

Sublease properties involve a complex contract structure with three parties: the owner, management company, and tenant. This guide clarifies key issues that foreign renters should understand beforehand—from confusion about points of contact when problems arise, to unclear responsibility in move-out settlements, to risks if the management company fails—from an industry practice perspective.

Understanding Owner Type to Ensure Rental Property Stability — Industry Knowledge for Foreign Residents Planning Long-Term Housing

How it differs from standard rentals:

For tenants, the lessor is the sublease company; there is no direct contractual relationship with the property owner.

Risks When Moving Into a Sublease Property

Risk 1: Sublease Company Bankruptcy

What happens to a tenant's lease if the sublease company goes bankrupt?

Key principle: The sublease contract between the tenant and sublease company generally continues. However, the following problems may arise:

  • •The rent payment recipient changes (which may cause confusion)
  • •Repairs and maintenance may be delayed or neglected
  • •If the owner terminates the sublease agreement, handling the tenant's situation becomes complicated

Under the Land and House Lease Law, there is case law indicating that "even if the contract between the lessor (sublease company) and the owner terminates, the tenant is protected for a certain period." However, because legally complex issues may arise, we recommend consulting a lawyer or Legal Aid Service immediately if bankruptcy information surfaces.

Risk 2: Problems Without Owner Notification

There are cases where sublease companies act inappropriately by placing tenants or reducing rent without the owner's permission. This is a hidden risk for tenants.

Risk 3: Unclear Contract Terms

The disclosure document for sublease properties must clearly state "this is a sublease property" and include "information about the sublease company (sublessor)." Caution is warranted if this is unclear.

Documents and Items to Verify Before Move-In

Points to verify when considering moving into a sublease property:

  1. The "lessor" name on the lease agreement: Is it the property owner (individual or company) or the sublease company?
  2. Does the disclosure document mention "sublease property"?
  3. The sublease company's financial condition, founding date, and reviews (major companies with long-term operations tend to be more reliable)
  4. Contact information for repairs and emergency response (is it the sublease company or the management company?)

How to Identify a Healthy Sublease Property

Characteristics of problematic sublease companies:

  • •Company established within 3 years with limited track record
  • •Difficult to reach and low-quality customer service
  • •Lease does not clearly state "sublease" and has many opaque terms

Characteristics of trustworthy sublease companies:

  • •Major real estate firms or large homebuilders (Daikentaku, Leopalace, Sekisui House, etc.)
  • •Long operating history with a large number of managed properties
  • •24-hour helpline for repairs and emergency response

For foreign residents, decisions often prioritize "foreign resident accommodation, English communication, and guarantor company options" over whether the property is a sublease. However, verifying the sublease company's reliability is still worthwhile.
