A foreign company that registers a Japan branch (外国会社の日本営業所) and whose closest Japanese equivalent is a 株式会社 (KK, joint-stock company) must publish its own balance sheet (貸借対照表) in Japan every year, under Companies Act (会社法) Article 819 (会社法第819条). A KK subsidiary only ever discloses its own numbers; a GK subsidiary discloses nothing at all. The branch route is the one structure of the three that can pull a foreign parent's own financials into a Japanese public filing.
What Is a Japan Branch, Legally?#
A Japan branch is the foreign company itself, registered to carry on continuous business in Japan under its own name, without the separate legal personality a KK or GK subsidiary has.
Applicants sometimes treat 支店 or 営業所 registration as a lightweight, cut-rate alternative to incorporating a subsidiary. On liability it is the opposite: the foreign parent stays directly on the hook for everything the branch does in Japan, because there is no separate entity to contain that liability. The mechanics of the registration itself, including the representative appointment and the parent-side document package, are covered in the Japan Foreign Company Registration guide; this post focuses narrowly on the disclosure consequence that catches most applicants off guard.
Why Does a Foreign Branch Have to Publish the Parent's Balance Sheet?#
Because Companies Act Article 819 (会社法第819条) treats a registered foreign company (外国会社) as if it were the Japanese entity type it most resembles, and applies that entity type's disclosure duty to it. If the parent's closest domestic equivalent is a 株式会社, the parent inherits the KK's annual balance-sheet publication obligation, applied to the parent's own accounts, not to a separate Japan-only set of books.
This sweeps in a wide range of foreign entity types. A Spanish sociedad anónima (S.A.), a German Aktiengesellschaft (AG), a French société anonyme (S.A.), and comparable share-capital corporations from other jurisdictions are all treated as KK-equivalent, which puts their own balance sheets into scope. The obligation attaches at the parent level, so a foreign board approving a Japan branch is also approving an annual disclosure of the parent's own financial position in a Japanese public filing, a consequence that rarely appears on the checklist when the branch is first proposed internally.
How Does This Compare to a KK or GK Subsidiary?#
A KK subsidiary only ever has to publish its own balance sheet; a GK subsidiary has no annual balance-sheet publication duty at all. The foreign branch is the most exposed of the three, because it is the only one where the disclosure reaches back to the parent's own accounts.
A KK subsidiary's disclosure duty (決算公告) runs under Companies Act Article 440 (会社法第440条), and it covers only the subsidiary's own financial statements. The parent's books never enter a Japanese public filing under that structure. A GK subsidiary has no equivalent annual publication requirement under Article 440 at all, since that article applies to 株式会社 only; the mechanics and exceptions of that GK position are covered in Does a Japan GK Have to Publish Financial Statements?. The foreign branch inverts that hierarchy: it is the structure most likely to force a foreign parent's own numbers into a Japan-facing publication, because the branch has no separate legal identity to shield behind.
Is a Japan Branch Actually Cheaper or Faster Than a Subsidiary?#
On neither count is a branch the lightweight option it is often assumed to be. Registration and license tax (登録免許税) for establishing the branch (営業所設置の登記) runs JPY 90,000, which is higher than a GK's minimum registration tax of JPY 60,000, and the branch still carries its own mandatory representative requirement that a subsidiary structure can now avoid.
Under Companies Act Article 817, Paragraph 1 (会社法第817条第1項), a foreign company doing continuous business in Japan must appoint a representative in Japan (日本における代表者), and at least one such representative must have an address in Japan. This applies whether or not the branch maintains a physical office. A KK or GK subsidiary does not carry this burden: Japan's Ministry of Justice abolished the resident-representative requirement for KK/GK directors as of March 16, 2015, so every director of a subsidiary may now live overseas. The branch has no equivalent relief; it always needs a Japan-resident representative, and where the company's first Japan branch registration is filed, that representative's own registration is bundled into the JPY 90,000 figure rather than billed separately. The branch must also be registered within three weeks of the date the office was established (営業所設置日), under Companies Act Article 933 (会社法第933条), a shorter runway than most applicants expect once the parent-side document package (certified incorporation evidence, articles, and proof of the representative's authority) is factored in.
The right way to choose a structure is to compare the branch against a KK or GK subsidiary on liability, disclosure, and representative requirements as well as headline setup cost, and that comparison is worth working through with a Japan market entry advisor before a branch is filed. Three points from that comparison weigh against the branch:
(a) A registered foreign company whose closest Japanese equivalent is a KK must publish its own balance sheet in Japan annually under Companies Act Article 819, pulling the parent's own accounts into a Japanese filing. (b) A KK subsidiary discloses only its own balance sheet under Companies Act Article 440; a GK subsidiary has no annual disclosure duty at all. The branch is the most exposed of the three structures. (c) The branch is not the cheaper or lighter filing either: registration and license tax is JPY 90,000 against a GK's JPY 60,000 minimum, and the branch always requires a Japan-resident representative under Article 817 with no equivalent to the 2015 relief that let every KK/GK director live overseas.
Frequently Asked Questions#
Does every foreign branch in Japan have to publish its parent's financials?
Only where the foreign company's closest Japanese equivalent is a 株式会社 (KK); that determination governs whether Companies Act Article 819 applies. A company whose home-jurisdiction form more closely resembles a GK-type entity would be assessed against the corresponding domestic equivalent, so the classification, not just the fact of branch registration, is what triggers the obligation. This should be confirmed with a qualified advisor before registering, since misclassifying the entity type carries real disclosure consequences.
Is a Japan branch cheaper than incorporating a KK or GK subsidiary?
A branch is not the cheaper route. Registration and license tax for the branch is JPY 90,000, above a GK's JPY 60,000 minimum, and the branch still requires a Japan-resident representative under Companies Act Article 817 with no capital or notarization steps saved that would offset the added disclosure and liability exposure. The genuine advantages, no paid-in capital requirement and no notarization of articles of incorporation (定款認証), matter most where the parent itself must be the contracting party in Japan, such as certain licensing or tender situations.
If I just want to test the Japan market without registering anything, what are my options?
A representative office (駐在員事務所) allows market research and liaison activity without triggering branch registration, the Article 819 disclosure duty, or the three-week filing deadline under Article 933, though it cannot conduct sales activity. The scope and limits of that structure are covered in the Japan Representative Office guide, and it is worth reviewing before committing to a branch or subsidiary structure.
