第三章 商業登記

Article 9Effect of Registration
第九条（登記の効力）
Information that must be registered pursuant to the provisions of this Part may not be asserted against a third party in good faith until after the registration. The same applies after the registration if a third party had a legitimate reason for not knowing that the information was registered.
この編の規定により登記すべき事項は、登記の後でなければ、これをもって善意の第三者に対抗することができない。登記の後であっても、第三者が正当な事由によってその登記があることを知らなかったときは、同様とする。
A person that registers false information intentionally or through negligence may not assert the falsity of that information against a third party in good faith.
故意又は過失によって不実の事項を登記した者は、その事項が不実であることをもって善意の第三者に対抗することができない。

この編の規定により登記した事項に変更が生じ、又はその事項が消滅したときは、当事者は、遅滞なく、変更の登記又は消滅の登記をしなければならない。
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)).
