Right of lease

The right a lessee (賃借人) has under a lease (賃貸借): to use the leased thing and take what it yields, in return for paying rent (Civil Code, Article 601). The lessee may not transfer it, or sublet the thing, without the lessor's (賃貸人) consent (Article 612, paragraph (1)). A registered lease of land or a building can be asserted against a person who acquires a right in rem (物権) in the property, such as a buyer, and against other third parties (Article 605), and a right of lease can be registered (Real Property Registration Act, Article 3, item (viii)). The Act on Land and Building Leases also protects a tenant who has not registered the lease: a right to use land for a building (借地権) can be asserted against third parties once the tenant owns a registered building on the land (Article 10, paragraph (1)), and a building lease takes effect against anyone who later acquires a right in rem in the building once the building has been handed over (Article 31).
