はじめに Introduction

Renting an apartment or house in Japan involves a web of rights and obligations governed primarily by the 借地借家法 (Act on Land and Building Leases) and the 民法 (Civil Code). Many tenants — both Japanese nationals and foreign residents — are unaware of the strong protections afforded to them under Japanese law. This guide covers the key rights every renter in Japan should know.

契約更新の権利 Right to Contract Renewal

Standard lease agreements (普通賃貸借契約) in Japan heavily favor the tenant when it comes to renewal:

  • A landlord cannot refuse to renew a lease without a "legitimate reason" (正当事由)
  • "Legitimate reason" is a high bar — personal use by the landlord or major renovation may qualify, but simply wanting the property back generally does not
  • If neither party gives notice before the renewal deadline, the contract automatically renews under the same terms (法定更新)

Note: 定期借家契約 (Fixed-term lease contracts) do not automatically renew and are increasingly common, especially in newer properties. Always check which type of contract you are signing.

立退き料 Compensation for Eviction Requests

If a landlord has legitimate reason to reclaim the property but the tenant has not violated the lease, the landlord is typically expected to offer 立退き料 (move-out compensation). There is no fixed legal amount, but compensation often covers:

  • Moving costs
  • Key money (礼金) for a new apartment
  • Several months' equivalent rent

敷金の返還 Security Deposit Returns

The return of the 敷金 (security deposit) is a common source of disputes. Key rules under the Civil Code and national guidelines include:

  • The landlord may only deduct from the deposit for damage caused by the tenant's negligence or misuse (故意・過失による損傷)
  • Normal wear and tear (通常損耗) — such as minor scuffs on walls, faded flooring from sunlight — is the landlord's responsibility, not the tenant's
  • The Ministry of Land, Infrastructure, Transport and Tourism has published guidelines (原状回復をめぐるトラブルとガイドライン) that courts regularly rely upon in disputes
  • Landlords must return the deposit promptly after lease termination, minus any legitimate deductions with a written explanation

修繕義務 Landlord's Duty to Repair

Under Article 606 of the Civil Code, landlords are legally obligated to maintain the property in a livable condition. This means:

  • The landlord must repair broken plumbing, heating systems, or structural defects at their own cost
  • If the landlord refuses necessary repairs, the tenant may be able to reduce rent proportional to the reduced utility of the property
  • In extreme cases, tenants may be entitled to terminate the contract

家賃滞納と強制退去 Rent Arrears and Eviction

A landlord cannot simply change the locks or remove a tenant's belongings — this constitutes self-help eviction (自力救済) and is illegal in Japan. To legally evict a tenant, the landlord must go through the court system, which involves:

  1. Filing a termination notice (解約通知) citing arrears
  2. Filing a civil lawsuit if the tenant does not vacate
  3. Obtaining a court judgment and enforcement order

The process typically takes several months, giving tenants significant time even in cases of arrears. That said, accumulated debt must eventually be repaid.

まとめ

Japanese law provides tenants with robust protections that many renters are unaware of. Understanding your rights around lease renewal, deposit returns, and the limits of landlord power can prevent you from being taken advantage of. When disputes arise, document everything in writing and seek advice from a legal hotline early — many issues can be resolved without going to court.
