merchant
「商人」
A person who, in their own name, carries on commercial transactions (商行為) as a business.
Defined inArticle 4, paragraph (1)· applies throughout the law
assert against
対抗
To be able to rely on a right, or on a fact about it, against someone who is not a party to it. Acquiring, losing or changing a right in rem (物権) in land or a building cannot be asserted against third parties until it is registered (登記) (Civil Code, Article 177), and a registered lease of land or a building can be asserted against a person who acquires a right in rem in it, such as a buyer, and against other third parties (Article 605). The Act on Land and Building Leases lets a tenant do without registering the lease itself: 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, such as a new owner, once the building has been handed over (Article 31). Some rules protect only a third party who did not know: a rescission for fraud cannot be asserted against a third party who did not know of the fraud and was not careless in not knowing (善意でかつ過失がない) (Civil Code, Article 96, paragraph (3)).

registration
登記
Entry in a public register kept by a registry office (登記所) — a Legal Affairs Bureau or one of its branch offices — so that the matter is made public (Real Property Registration Act, Articles 1 and 6, paragraph (1)). Rights in land and buildings, such as ownership, a superficies (地上権), a statutory lien (先取特権), a mortgage and a right of lease (賃借権), can be registered under that Act (Article 3), and matters the Commercial Code, the Companies Act and other Acts require to be registered are registered under the Commercial Registration Act (Article 1). Registration also lets a right be asserted against third parties: acquiring, losing or changing a right in rem (物権) in land or a building, such as ownership, cannot be asserted against third parties until it is registered (Civil Code, Article 177), and a matter the Companies Act requires to be registered cannot be asserted against a third party who does not know of it until it has been registered, nor, even after that, against one who had a justifiable reason for not knowing of the registration (Companies Act, Article 908, paragraph (1)).
