借地借家法第26条
Renewal of Building Lease Agreements
建物賃貸借契約の更新等
Plain-language explanation
Article 26 of the Act on Land and Building Leases governs what happens when a building lease (commercial or residential) reaches the end of its fixed term. If neither the landlord nor the tenant gives notice of non-renewal within the statutory notice period before expiration, the lease is automatically deemed renewed on the same terms as before — except that the renewed lease becomes one without a fixed term (i.e., open-ended, terminable by notice going forward).
Critically, a landlord cannot simply refuse to renew by sending a notice; Japanese law requires the landlord to also demonstrate "justifiable grounds" (正当事由) — such as a genuine need to use the property personally, or an offer of compensation (立退料) to the tenant — before non-renewal notice becomes legally effective. This makes it quite difficult for landlords to terminate ongoing leases, reflecting the law's strong tenant-protection policy. Tenants, by contrast, generally have more freedom to decline renewal or terminate.
This article is central to disputes over office leases, retail store leases, and residential apartment renewals in Japan. Landlords who assume that a lease automatically ends at the stated term — or that a simple non-renewal letter suffices — are often surprised to learn the lease continues under statutory renewal unless proper legal grounds and procedures are followed. Business owners renting commercial space should build in realistic timelines and negotiation strategies around this rule rather than relying solely on contract language.
日本語での解説
借地借家法第26条は、建物の賃貸借契約(いわゆる借家契約)の期間満了時の更新に関する基本的なルールを定めた条文です。契約期間が満了しても、当事者(貸主・借主)が期間満了の一定期間前までに更新をしない旨の通知をしなかった場合、契約は従前と同一条件で自動的に更新されたものとみなされます。ただし、期間についてのみ「定めのないもの」として扱われる点が特徴です。
貸主が更新を拒絶するためには、単に通知をするだけでなく、正当事由(貸主自身の使用の必要性、立退料の提供など)が必要とされており、借主保護の観点から貸主側の更新拒絶のハードルは高く設定されています。逆に、借主が更新を望まない場合は、比較的自由に解約を申し入れることができます。
実務上、賃貸借契約書に「期間満了により契約は終了する」旨の特約を設けても、正当事由なく更新拒絶通知をしただけでは法定更新の効力を排除できないケースが多く、貸主側は特に注意が必要です。オフィス賃貸や店舗賃貸、居住用マンションの契約更新の場面で頻繁に問題となる条文です。
