Foreign-owned Japan companies are not static structures. A KK, Kabushiki Kaisha (株式会社) or GK, Godo Kaisha (合同会社) that was correct at incorporation often needs adjustment as the business scales: a private equity investor wants in, a holding structure becomes necessary for tax efficiency, two Japan subsidiaries need to merge, or a division is being carved out before a sale. Japan's Companies Act (会社法) provides a set of statutory restructuring mechanisms that allow foreign owners to reorganize without dissolving and re-registering. Each mechanism has its own procedure, cost, timeline, and regulatory overlay. This guide maps the five primary options, their FEFTA implications, and the labor obligations that apply.
Why Foreign Owners Restructure Japan Companies
The trigger is usually one of six situations:
(a) New investor entry: a PE fund, strategic partner, or co-investor wants an equity stake. Issuing new shares in an existing KK is faster and cheaper than winding down and restarting with a new cap table.
(b) PE exit preparation: selling a Japan subsidiary to a third party is cleaner when it sits inside a standalone KK with auditable governance rather than as an unincorporated branch or a GK with informal management.
(c) Group consolidation: multinationals that acquired Japan companies independently often end up with two or three Japan entities doing overlapping work. An absorption merger or corporate split lets them consolidate without the cost of running duplicate legal entities.
(d) FEFTA compliance: certain reorganizations between group entities, including intra-group share transfers and capital increases, may trigger Foreign Exchange and Foreign Trade Act (外為法) notification obligations depending on the sectors involved. Getting ahead of this before restructuring avoids post-close regulatory exposure.
(e) Tax efficiency: interposing a Japan holdco above an operating KK can facilitate dividend pooling, IP holding, and transfer pricing management. Tax structuring is a matter for a Licensed Tax Accountant (税理士) and falls outside the scope of this regulatory guide, but the legal mechanism that enables the holdco structure is the share exchange discussed in Option 3 below.
(f) GK-to-KK upgrade: a GK is structurally unsuitable for bank financing, regulated licenses, and certain customs registrations. soshiki henkou (組織変更) from GK to KK solves this without losing the entity's registration history or bank account.
Restructuring Option 1: Capital Increase to Bring In New Investors
A capital increase through shinkabu hakko (新株発行) is the most common restructuring tool for KK companies receiving outside investment.
Under 会社法, a KK may issue new shares to one or more specific subscribers through a third-party allotment capital increase (第三者割当増資). The procedure is:
(a) Board of directors passes a resolution specifying the number of shares to be issued, the issue price, the payment date, and the identity of the subscriber.
(b) If the issue price is materially below the market value of existing shares (有利発行), shareholder approval by special resolution (特別決議) at a general meeting of shareholders (株主総会) is required under 会社法. For a closely held KK with a sole foreign parent as the only shareholder, this formality is straightforward but must be documented.
(c) The subscriber pays the agreed amount into the KK's bank account on or before the payment date.
(d) The representative director files a change registration (変更登記) at the Legal Affairs Bureau (法務局) within two weeks of the payment date. The registration updates paid-in capital (資本金) and the share ledger.
Key considerations:
Dilution: existing shareholders are diluted pro rata. Where the existing parent holds 100% of the KK, a third-party allotment at any price creates a minority shareholder. A shareholder agreement (株主間契約) governing governance rights, transfer restrictions, and exit is advisable before the new shares are issued.
Valuation: Japan does not require a formal independent valuation for closely held KK share issuances, but the issue price should be defensible from a transfer pricing and tax perspective if the subscriber is a related party. An unverified-low price to a related party may be re-characterized as a deemed gift or non-arm's-length contribution by the National Tax Agency (国税庁).
Registry update: paid-in capital changes must be registered. Note that reducing capital (資本金の減少) also requires special shareholder resolution and a creditor protection procedure (債権者保護手続) under 会社法.
Restructuring Option 2: Converting a GK to a KK
soshiki henkou (組織変更) is the statutory mechanism for converting a GK into a KK or vice versa. Converting a GK to a KK is the more common direction for foreign-owned companies.
GKs are suitable for wholly owned single-purpose structures. They become a liability when the company needs: a corporate bank account at a major bank, a customs broker (通関業者) registration, certain PSE-related regulatory licenses, or the credibility that a KK signals to Japanese clients and counterparties. Banking is the most common pressure point: major Japanese banks treat GKs as structurally less creditworthy, and some refuse corporate accounts outright.
Procedure:
(a) Pass a unanimous resolution of all 社員 (members) approving the 組織変更 plan (組織変更計画). The plan must specify the new KK's 定款 provisions, the identity of the initial directors, and any auditor appointments required by 会社法.
(b) Conduct a creditor protection procedure: the company must notify known creditors and publish a public notice in the Official Gazette (官報) allowing creditors one month to object. This adds approximately five to six weeks to the timeline.
(c) After the objection period closes, file a simultaneous dissolution registration for the GK and incorporation registration for the KK at the 法務局. The two registrations are submitted together on the effective date of conversion.
(d) Open or migrate the banking relationship. Existing bank accounts held in the GK's name do not automatically transfer. Coordinate with the bank in advance.
Cost and timing: Registration costs include a registration tax (登録免許税) of JPY 60,000 for the dissolution registration and a tax based on capital for the new KK incorporation. judicial scrivener (司法書士) fees typically run JPY 80,000 to 150,000. Total elapsed time from resolution to completed registration: eight to ten weeks when creditor protection runs smoothly.
Restructuring Option 3: Moving to a Holding Company Structure
The kabushiki koukan (株式交換) mechanism under 会社法 allows a new or existing Japan KK to become the 100% parent of an operating KK by exchanging shares, without any cash changing hands between the entities.
In a wholly owned share exchange (完全子会社化):
(a) A new Japan HoldCo KK is incorporated (or an existing KK is designated as the parent).
(b) The HoldCo and the operating KK enter into a share exchange agreement (株式交換契約) specifying the exchange ratio.
(c) Shareholders of the operating KK surrender their shares and receive HoldCo shares in return. The operating KK becomes a 100% subsidiary of HoldCo.
(d) Both entities file 変更登記 to reflect the new ownership structure.
When it is used: the holdco structure is typically adopted when: (i) a foreign group wants a Japan intermediate holding entity for dividend consolidation; (ii) an IP holding structure is being set up above the operating entity; (iii) the Japan operations are being prepared for an eventual partial sale where the buyer will purchase the HoldCo rather than directly acquiring the operating KK; or (iv) multiple operating KKs are to be consolidated under a single Japan parent.
Tax impact: The tax treatment of the 株式交換 depends on whether it qualifies as a tax-qualified reorganization (適格組織再編) under Japan corporate tax law. A qualified exchange results in no immediate tax event for shareholders; an unqualified exchange triggers recognition of gain on the shares exchanged. This analysis must be performed by a Licensed Tax Accountant (税理士) before executing the exchange. Aplash's role is the regulatory and corporate law implementation; tax structuring advice is provided separately.
Restructuring Option 4: Merging Two Japan Entities
kyushu gappei (吸収合併) under 会社法 is the mechanism for merging two Japan entities, with one entity (the surviving entity) absorbing the other (the dissolving entity). The dissolving entity ceases to exist; all its rights, obligations, and contracts transfer to the survivor by operation of law.
Foreign owners with two Japan KKs or a KK and a GK doing overlapping work commonly use 吸収合併 to: eliminate duplicate annual compliance costs (audit, tax filings, director appointments), consolidate banking relationships, present a single legal entity to regulators and clients, and simplify the group structure ahead of an exit.
A standard 吸収合併 takes four to five months from initial board resolutions to completion of registration. The mandatory steps include:
(a) Board resolutions approving the merger agreement (合併契約) at both entities; shareholder approval by special resolution (特別決議) at both entities unless a simplified merger procedure applies.
(b) Creditor protection procedure: public notice in 官報 and individual notice to known creditors; creditors have one month to object. The merger cannot complete until this period expires and objections are resolved.
(c) Notification or reporting to relevant regulators, including the Japan Fair Trade Commission (公正取引委員会) if the Antimonopoly Act (独占禁止法) notification thresholds are met.
(d) Registry filings at 法務局 to record the dissolution of the absorbed entity and the change in the surviving entity's particulars.
All employment contracts of the absorbed entity transfer to the surviving entity by operation of law as a result of the merger. See the Labor Obligations section below.
Restructuring Option 5: Corporate Split / Carve-Out
kaisha bunkatsu (会社分割) is the mechanism for transferring a defined business unit, including its contracts, assets, liabilities, and employees, from one Japan entity to another. It is used to carve out a division before a sale, to separate a regulated business from an unregulated one, or to allocate distinct operations to separate legal entities within a group.
Two forms:
(a) kyushu bunkatsu (吸収分割): the carved-out business unit transfers to an existing company.
(b) shinsetsu bunkatsu (新設分割): the carved-out business unit transfers to a newly incorporated entity created as part of the split.
A 会社分割 is commonly used when a buyer wants to acquire a specific business line from a Japan company without acquiring the entire entity and its legacy liabilities. By splitting the target business into a clean NewCo and then selling NewCo, the seller limits what transfers to the buyer and retains legacy matters in the RemainCo.
Procedure:
(a) The board approves a split plan (分割計画) or split agreement (分割契約), identifying the specific rights, obligations, contracts, assets, and employees to be transferred.
(b) Creditor protection procedure: public notice and individual notices, with a one-month objection period.
(c) Employees whose primary duties relate to the transferred business are transferred to the successor entity (see Labor Obligations below).
(d) Registry filings at 法務局 to record the split.
FEFTA Implications of Internal Restructuring
Not all intra-group reorganizations are FEFTA-exempt. Foreign owners should assess each restructuring step against 外為法 before executing.
Under 外為法, foreign investment in Japan companies operating in designated sectors requires pre-notification (事前届出) to the relevant ministries. The designated sectors include telecommunications, broadcasting, energy, financial services, security-related businesses, and certain technology areas. The obligation applies not only to arm's-length acquisitions but also to intra-group share transfers and capital increases.
Specifically, a capital increase that results in a foreign investor holding or increasing a stake above the applicable notification thresholds in a sector-designated KK requires pre-notification even if the investor is an existing shareholder of the parent group. A 株式交換 that interposes a new Japan HoldCo between a foreign parent and a sector-designated operating KK may also require analysis, since the operating KK's direct shareholder changes.
Practical safe harbors:
(a) Purely internal downstream mergers (where a foreign parent's 100% Japan subsidiary absorbs another 100% Japan subsidiary of the same foreign parent) generally do not alter the ultimate foreign ownership position and are typically low-risk for FEFTA pre-notification purposes. This is a fact-specific assessment.
(b) A GK-to-KK conversion (Option 2) does not change the ownership structure and does not by itself trigger 外為法 notification.
(c) A 会社分割 that creates a new Japan entity within the same 100% foreign-owned group and does not involve a sector change is typically low-risk, but the transferred business's sector designation should be confirmed.
Any restructuring touching a sector listed under 外為法 Article 26 requires Director review before proceeding. Aplash provides FEFTA pre-notification support as a separate engagement.
Labor Obligations When Restructuring
Mergers and corporate splits trigger mandatory employee notification and consultation obligations under Japan labor law. Failure to comply can invalidate the restructuring step or expose the company to damages claims.
For corporate splits (会社分割), the Labor Contract Succession Act, R1 (労働契約承継法) governs the transfer of employment contracts. Key obligations:
(a) Notice to employees: at least two weeks before the effective date of the split, employees whose contracts will transfer must receive individual written notice specifying: the details of the split, the fact of the transfer, and the identity of the successor entity.
(b) Right to object: employees who are primarily assigned to the business unit being transferred but do not want their contracts to transfer may object in writing within the notice period. If they object, their contracts remain with the original entity.
(c) Employees not assigned to the split unit: if the split plan purports to transfer an employee whose primary duties are not in the split unit, that employee may object and their contract will transfer back to the original entity.
In an kyushu gappei (吸収合併), all employment contracts of the absorbed entity transfer to the surviving entity by operation of law. There is no statutory right of individual employees to object to the transfer in a merger. However:
(a) Under Labor Contract Act (労働契約法) and Labor Standards Act (労働基準法), the terms and conditions of transferred employees cannot be unilaterally worsened by the surviving entity.
(b) Collective bargaining agreements (労働協約) of the absorbed entity bind the surviving entity for a limited period.
(c) A mass dismissal for business reasons (整理解雇) executed in connection with the merger must satisfy the 整理解雇の4要件: genuine necessity, exhaustion of alternatives, rational selection criteria, and appropriate consultation procedure. A merger alone does not create grounds for dismissal; redundancy caused by consolidation may, but all four requirements must be met.
Registry and Filing Requirements for Each Option
Each restructuring mechanism requires filings at the Legal Affairs Bureau (法務局). The key requirements by option:
(a) Capital increase (Option 1): 変更登記 within two weeks of the payment date. Required documents: board resolution, shareholder resolution if applicable, bank confirmation of payment, updated shareholder register.
(b) GK-to-KK conversion (Option 2): simultaneous dissolution and incorporation registrations on the effective date. Required documents: 組織変更計画, member resolution, new 定款, creditor protection evidence, initial directors' consent forms.
(c) Share exchange (Option 3): 変更登記 at both HoldCo and the operating KK. Required documents: 株式交換契約, shareholder resolutions at both entities, evidence of share exchange ratio.
(d) Absorption merger (Option 4): dissolution registration for the absorbed entity and 変更登記 for the surviving entity. Required documents: 合併契約, shareholder resolutions at both entities, creditor protection evidence, balance sheet of the absorbed entity.
(e) Corporate split (Option 5): 変更登記 at the original entity and, for 新設分割, an incorporation registration for the new entity. Required documents: 分割計画 or 分割契約, shareholder resolutions, creditor protection evidence, employee notification records under R1 (労働契約承継法).
In all cases, a judicial scrivener (司法書士) handles the registry filings.
How Aplash Can Help
Aplash is a Japan regulatory strategy and market entry firm. Our role in corporate restructuring engagements covers:
(a) Regulatory mapping: identifying which restructuring mechanism fits the client's objective, assessing FEFTA pre-notification obligations for each step, and flagging labor law compliance requirements before execution begins.
(b) FEFTA pre-notification support: preparing and submitting 外為法 pre-notifications to the relevant ministries for restructuring steps involving sector-designated entities or threshold-crossing share transfers.
(c) Corporate law implementation coordination: managing the end-to-end procedural timeline across the restructuring, coordinating with the 司法書士 on registry filings, and liaising with the client's tax advisor and legal counsel on their respective workstreams.
(d) Post-restructuring compliance: updating 定款 目的 clauses to reflect the reorganized business scope, reviewing intercompany agreements between the new holding and operating entities, and advising on ongoing annual compliance obligations under the new structure.
For restructuring steps involving FEFTA prior-notification sectors, dual-use matters, or three or more ministry filings, Director review is required before Aplash provides written analysis.
