A foreign owner sells a Japan company through one of two structures: a share sale (transfers the entity itself, including all liabilities) or an asset sale (transfers selected business assets, leaving the entity behind). Most foreign sellers of a Japan subsidiary use a share sale for its cleaner capital gains tax treatment and automatic transfer of contracts, licenses, and employees. The process runs 5 to 6 months from preparation to closing, longer if the buyer is a foreign investor in a Foreign Exchange and Foreign Trade Act (外為法, FEFTA) designated sector.
Key points at a glance:
(a) Structure: a share sale is the default for most foreign-owned subsidiaries; an asset sale is used only when specific liability carve-outs are required or when part of the business is being divested. (b) Regulatory gate: FEFTA designated-sector deals add 30 to 60 days for prior notification and clearance, which must begin before any binding agreement is signed. (c) Tax exposure: a non-resident seller with no Japan permanent establishment is generally exempt from Japan capital gains tax, unless the 25/5 ownership-and-disposal rule or the real-estate-rich test applies.
What Are the Most Common Reasons Foreign Owners Sell a Japan Company?
Japan is the world's third-largest economy but has some of the lowest M&A sell-side activity per GDP of any major developed market. Foreign-owned Japanese companies still change hands regularly, driven by:
- Parent company restructuring or portfolio rationalization
- Market exit following an unsuccessful Japan expansion
- Opportunistic strategic sale at peak valuation
- Succession planning where no Japan-based heir to the business exists
- Management buyout initiated by a local management team that knows the business
The mechanics of selling a Japan entity are governed by the Companies Act (会社法), the Foreign Exchange and Foreign Trade Act (外為法 / FEFTA), National Tax Agency (NTA) rules on capital gains, and employment protection law. Each of these creates obligations that are easy to overlook and expensive to discover late in a deal. A sale is the exit side of a structure many foreign owners entered as a joint venture, and the same FEFTA and Companies Act mechanics that shaped entry now shape exit.
Should You Sell Shares or Assets When Exiting a Japan Company?
Most foreign sellers of a Japan subsidiary should use a share sale: it carries cleaner capital gains tax treatment and transfers contracts, licenses, and employees automatically. An asset sale is the exception, used only when specific liabilities must be carved out or when just part of the business is being divested.
Share Sale (株式譲渡, share transfer, or 持分譲渡, membership interest transfer)
The seller transfers ownership of the Japanese entity. All assets, liabilities, employees, contracts, and licenses transfer automatically to the buyer.
Seller advantages:
- Capital gains tax treatment - cleaner than entity-level income tax on asset proceeds
- No need to individually transfer each contract, license, or regulatory filing
- Employees transfer automatically - individual consent is not required
- Clean exit: the seller has no further relationship with transferred assets or liabilities after closing
Seller disadvantages:
- Buyer inherits all known and unknown liabilities - buyers will price this into their offer or require reps and warranties insurance
- More extensive due diligence scrutiny of the entity's historical compliance and tax position
Asset Sale (事業譲渡)
The seller transfers selected business assets to the buyer. The Japanese legal entity remains with the seller, holding only residual assets not transferred.
Seller advantages:
- Can exclude specific liabilities from the transferred scope
- Retain the entity for other purposes if needed
Seller disadvantages:
- Each asset class requires separate transfer mechanics (real property, IP, equipment, receivables)
- Employees require individual consent to transfer - risk of key staff refusing
- Regulatory licenses must be re-applied for in the buyer's name; they do not transfer automatically
- Tax treatment: proceeds are typically treated as income at the entity level, not capital gains
For most foreign sellers exiting a Japanese subsidiary: Share sale is the cleaner, faster, and commercially preferable structure. Asset sales are used when specific liability carve-outs are required or when only a portion of the business is being divested. Whichever structure you choose, the buyer's due diligence process will test every item on this list, so preparing for it before marketing the company is the difference between a smooth process and a repriced deal.
How Are Japanese Companies Valued in an Exit Sale?
Japan M&A valuation follows the same methods used internationally, EV/EBITDA multiple, net asset value, DCF, and comparable transaction, but with Japan-specific adjustments that consistently surprise foreign sellers: retirement benefit liabilities, unrealized real estate appreciation, customer concentration, and key-man dependency all move the final number more than the choice of method does.
| Method | When Used | Japan-Specific Considerations |
|---|---|---|
| EV/EBITDA multiple | Operating businesses with recurring revenue | SME multiples are typically lower than Western equivalents; control premium varies by sector |
| Book value / net asset value | Asset-heavy businesses, real estate holdings | Fixed assets may carry significant unrealized appreciation; fixed asset tax (固定資産税) assessments are material inputs |
| DCF | Growth businesses with projectable cash flows | Discount rates tend to be conservative; near-term cash flow certainty is valued over long-term projections |
| Comparable transaction | Industry-specific benchmarks | Japan domestic M&A comps are more reliable reference points than cross-border comparables |
Japan-Specific Valuation Adjustments
Retirement benefit liabilities (退職金): Many established Japanese companies operate defined-benefit retirement plans. These appear on financial statements but are often under-funded. Buyers apply a haircut, and sellers frequently underestimate this impact on net proceeds.
Real estate: Property assets may carry significant unrealized appreciation (含み益). Both sides need independent appraisal. Sellers should obtain this proactively rather than accepting the buyer's valuation.
Customer concentration: Japanese buyers place high value on diversified customer bases. Single-customer dependency - even if revenue is stable - is a significant valuation discount.
Key-man dependency: If the seller (or a key manager) will exit post-sale, buyers will discount heavily for transition risk. Retention packages for key management, and a structured handover period, protect seller valuation.
What FEFTA Obligations Apply When Selling a Japan Company?
The Foreign Exchange and Foreign Trade Act (外国為替及び外国貿易法, FEFTA) is typically framed as a buyer-side obligation, but the seller's sector classification and cooperation are directly material to deal timing. If the buyer is a foreign investor and the target sits in a designated sensitive sector, prior notification and a 30-day review period must clear before any binding agreement is signed.
When the Buyer Is a Foreign Investor
If your buyer is a foreign company or non-resident investor:
| Sector | FEFTA Obligation |
|---|---|
| Non-designated sector | Buyer files post-investment notification within 15 days of closing. Seller has no direct filing obligation but must cooperate with buyer's information requests about the company's activities. |
| Designated sensitive sector | Buyer must file prior notification before signing any binding agreement. Closing is blocked until the 30-day review period clears. Deal structure and timeline must accommodate this from the outset. |
When the Buyer Is a Japanese Party
No FEFTA prior notification is required for acquisitions by Japan-resident buyers. Post-investment notification requirements may still apply if the selling entity is foreign.
Seller's Practical Obligation
Confirm your target company's FEFTA sector classification as part of pre-sale preparation - before you begin marketing. A surprise designation delays the deal by 30 to 60 days and gives buyers leverage to reprice or impose additional conditions.
Designated sectors as of 2026 include: defense and defense-adjacent manufacturing, telecommunications, energy, transportation, agriculture, financial services, IT (including cybersecurity), and pharmaceuticals / medical devices.
How Much Tax Does a Foreign Seller Pay When Exiting a Japan Company?
A non-resident seller with no Japan permanent establishment is generally exempt from Japan capital gains tax on a share sale, unless the 25/5 ownership-and-disposal rule is triggered or the target is a real-estate-rich company. Tax treaties can eliminate Japan's taxing right even where the 25/5 rule would otherwise apply.
Corporate Seller (Foreign Parent Selling a Japan Subsidiary)
The default position under Japan domestic law is that a non-resident foreign corporation with no permanent establishment (PE) in Japan is not subject to Japanese corporate tax on capital gains from the sale of Japanese shares. This default is then narrowed by statutory exceptions.
| Scenario | Japan Tax Treatment |
|---|---|
| Non-resident corporate seller, no Japan PE, no triggering exception | Generally exempt from Japan capital gains tax |
| 25/5 rule triggered (seller held 25% or more of the issued shares of the Japan target at any point in the three-year period ending on the disposal date, AND disposes of 5% or more of issued shares in aggregate in the same fiscal year) | Capital gain taxable in Japan at standard corporate tax rates (combined ~30%) |
| Real-estate-rich target (more than 50% of the target's asset value consists of Japanese real property) | Capital gain taxable in Japan |
| Seller has a Japan PE and the shares are attributable to the PE | Taxable in Japan |
| Tax treaty override | Many treaties (e.g. Japan-UK, Japan-Germany, Japan-Singapore) eliminate Japan's taxing right on share capital gains even when the 25/5 rule would otherwise apply; treaty terms vary by counterparty jurisdiction |
There is no general domestic withholding tax on a non-resident's sale of Japanese shares. (The 10.21% withholding that applies to non-resident dispositions of Japanese real property does not apply to share transactions.)
Key action before structuring your exit: Confirm the following three points with a tax advisor before any binding discussions: (1) whether the 25/5 rule is triggered by your historical ownership and planned disposal, (2) whether the target is a real-estate-rich company, and (3) how your home-country treaty with Japan treats share capital gains. These three points determine whether Japan retains any taxing right at all, which is far more consequential than treaty rate mechanics.
Individual Seller (Foreign Individual Holding Japan Shares Directly)
The same framework applies to non-resident individuals with important differences from the resident regime:
| Scenario | Japan Tax Treatment |
|---|---|
| Non-resident individual, no Japan PE, no triggering exception | Generally exempt from Japan capital gains tax on unlisted share sales |
| 25/5 rule triggered for individual sellers | Capital gain taxable in Japan (rate and mechanics differ from resident regime; individual-specific rates apply) |
| Real-estate-rich target | Capital gain taxable in Japan |
| Tax treaty relief | Often available; confirm under the seller's residence-country treaty with Japan |
For reference, the 20.315% flat rate (15.315% national including 0.315% reconstruction surtax, plus 5% local inhabitant tax) applies to Japan-resident individuals on unlisted share capital gains. Non-residents without a Japan PE are not generally subject to this rate.
Who Buys Japanese Companies From Foreign Sellers?
The four active buyer types are Japanese strategic buyers, private equity or search funds, management buyout teams, and foreign strategic buyers, and each expects a different negotiation pace and diligence scope.
| Buyer Type | Characteristics | Best For |
|---|---|---|
| Japanese strategic buyer | Pays premium for synergies; expects extended negotiation; decision process in Japanese | Established operations with a clear strategic fit for a Japan peer |
| Private equity (PE) / search fund | Valuation-driven; shorter diligence process; professional deal team | Profitable businesses with clean financials and management team willing to stay |
| Management buyout (MBO) | Existing management team acquires the business | Businesses where continuity of local management is key to value preservation |
| Foreign strategic buyer | Cross-border deal dynamics; FEFTA screening required if designated sector | Foreign companies seeking Japan market access via acquisition rather than greenfield |
For foreign sellers of small to medium Japan entities (annual revenue below ¥1 billion), the most active buyer pool is:
- Japanese SME strategic buyers in the same or adjacent sector
- Japan-focused PE funds and search fund operators
- Existing management team (MBO)
How Long Does It Take to Sell a Japan Company?
A typical sell-side process runs 5 to 6 months from preparation to closing, longer if FEFTA clearance is required. The stages run in sequence: preparation, marketing, diligence, negotiation, and closing.
Month 1 Month 2–3 Month 3–4 Month 4–5 Month 5–6
┌─────────────┐ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ ┌────────────┐

└─────────────┘ └─────────────┘ └─────────────┘ └─────────────┘ └────────────┘
Designated-sector transactions: add 30 to 60 days for FEFTA clearance, which must begin before any binding SPA is signed. Build this into the buyer marketing timeline, not as a post-LOI discovery.
What Mistakes Do Foreign Sellers Make When Exiting a Japan Company?
The recurring mistakes cluster around preparation, not negotiation: no pre-sale financial cleanup, undisclosed regulatory gaps, an unchecked FEFTA sector classification, and an unquantified retirement benefit obligation are the four that most often reprice or kill a deal during diligence.
| Mistake | Why It Happens | Prevention |
|---|---|---|
| No pre-sale financial cleanup | Books are maintained for operations, not buyer scrutiny | Engage a CPA 3–6 months before launch to clean intercompany transactions and confirm QIS status |
| Undisclosed regulatory issues treated as immaterial | Seller believes minor compliance gaps will not affect price | Full regulatory disclosure - hidden issues discovered during diligence reprice or kill deals |
| FEFTA surprise for buyer | Seller has not checked sector classification before marketing | Sector assessment is step one of sell-side preparation |
| Key employee departures during process | Staff hear about the sale indirectly and leave | Retention agreements for key employees before launch of any formal process |
| Seller's valuation based on replacement cost, not market evidence | Emotional attachment to the business | Obtain independent valuation or comparable transaction analysis before setting price expectations |
| Retirement benefit obligations not quantified | Often disclosed only in footnotes | Third-party actuarial assessment of retirement benefit (退職金) obligations before the NDA process begins |
Frequently Asked Questions
Do I need a Japan-based advisor to sell a Japan subsidiary, or can my home-country M&A team handle it directly?
A home-country M&A team can lead the transaction, but Japan-specific items, FEFTA sector classification, retirement benefit liability quantification, and Companies Act share transfer mechanics, require local regulatory expertise your team is unlikely to carry in-house. Engaging Japan market entry and exit advisory alongside your home-country deal team closes that gap without replacing your existing advisors.
Can a share sale close without any regulatory filing at all?
Only if the buyer is not a foreign investor and the target is not in a FEFTA designated sector. If either condition is not met, a notification filing (post-investment or prior, depending on sector) is required, and a designated-sector deal cannot close until the 30-day review period clears.
How early should I start preparing if I want to sell within 12 months?
Start financial cleanup and FEFTA sector classification 3 to 6 months before you intend to approach any buyer. Both take time to complete properly, and discovering either issue after a buyer has issued a letter of intent typically costs more in repricing than the preparation would have cost upfront.
