Acquiring a Regulated Financial Business in Japan

Buying a regulated financial business in Japan does not necessarily mean that its licence, registration or notified status moves with the business. Whether the regulatory status remains where it is, whether a new registration is required, or whether other procedures apply depends on both the regulated service and the transaction structure.

A share acquisition leaves the target legal entity in place, while a business transfer, company split or merger may move some or all of the business to another entity. Japanese financial legislation does not treat those structures uniformly: some regimes contain specific rules for particular forms of business succession, while others require the entity conducting the regulated activity after closing to hold the necessary regulatory status itself.

This guide is written for overseas acquirers and investors considering the acquisition of a regulated financial business operated in Japan. It covers payment services, prepaid payment instruments, cryptoasset and electronic payment instrument services, and money lending, and looks at how regulatory status, due diligence and post-closing operating changes interact with deal structure. For the general framework for acquiring a Japanese business — transaction structure, foreign investment screening, merger control, employment and the transaction documents — please see “M&A in Japan for Foreign Acquirers and Investors”.

Discuss a financial services acquisition in Japan

Our lawyers' backgrounds include secondment to a fintech business and work on M&A and listing preparation, and our work runs from the question of which rules apply to a service through due diligence, the transaction documents and the steps to be taken with the authorities. In due diligence we have handled, registration and notification issues have come to light that the target had not identified.

Before You Contact Us

The following helps us give a useful first answer. Nothing needs to be settled, and an enquiry at an early stage is welcome.

The regulated entity and its current status — please identify, so far as you know, which legal entity holds each registration or has made each notification, and which authority supervises the business.
How the service actually works — please describe who contracts with customers, who receives or holds money or other assets, how obligations are discharged, and how funds or assets move between the parties.
The proposed transaction structure — please let us know whether you are considering a share acquisition, business transfer, company split, merger or another structure. It is also fine if the structure has not yet been decided.
Proposed ownership and management changes — please share the proposed ownership structure and any planned changes to directors, other management personnel or the entities responsible for regulated functions.
Customer money and other assets — please identify any customer funds, unused prepaid balances, cryptoassets, electronic payment instruments or other assets held, and the arrangements used to safeguard or manage them.
Regulatory history — please share any material filings, inspections, requests for reports, incidents, compliance issues or correspondence with regulators that may be relevant to the business.
The post-closing operating model — please describe any planned changes to products, funds flows, customer-asset arrangements, outsourcing, systems, service providers or the group entity performing a particular function.
Timetable and other advisers — please provide the proposed signing and closing timetable, any discussions already held with regulators, and information on overseas counsel, financial, tax or other advisers involved in the transaction.

Please begin with a short overview rather than sending transaction documents or customer information with your first enquiry. Once we have confirmed that we are able to act, we will explain how to share detailed material.

Frequently Asked Questions

Does the Regulatory Status Stay with the Business?

Ask which entity will conduct the regulated activity after closing

The first question is not simply whether the target has a licence or registration today. It is which legal entity holds that regulatory status, which entity will conduct the regulated activity after the transaction, and whether those will remain the same. A share acquisition, a business transfer, a company split and a merger can therefore produce materially different regulatory consequences even where the commercial objective is the same.

A further distinction is important. Japanese financial legislation may contain provisions dealing with succession to a business without providing that the relevant registration itself passes to the successor. In those cases, the fact that contracts, assets or operations may be succeeded to under the transaction does not mean that the regulatory status automatically passes with them. Conversely, some regimes contain specific statutory treatment for particular forms of business succession. The relevant statute therefore has to be checked service by service.

The table below gives a transaction-level overview. It is intended to identify the regulatory question that should be resolved when selecting the deal structure, rather than to state every filing required in an individual transaction. Changes to officers, offices, business methods, products, outsourcing arrangements or customer-asset arrangements can each give rise to their own procedures, and the required steps depend on the resulting structure and on the regulated activities that will continue after closing.

Regulatory status	Share acquisition	Business transfer	Company split	Merger
Funds transfer service	The registered legal entity remains the same, so the registration ordinarily remains with the target. The acquisition does not itself transfer it. Changes to registered particulars may require filings.	The legislation addresses discontinuance where the business is succeeded to, but does not provide for the registration itself to pass. A transferee carrying on the business must itself be registered.	The same distinction applies. The statutory rules contemplate succession of the business, not transfer of the registration. The company conducting the service after the split must itself be registered.	If the registered company survives, its registration remains with the same entity, subject to change procedures. If it disappears, the registration does not pass to the survivor by merger alone.
Prepaid payment instruments (self-use)	Where the issuer itself remains in existence, a share acquisition does not move its status to another entity. Changes to notified particulars may require a filing.	A special rule may treat a person succeeding to the issuance business as a self-use issuer in specified circumstances, with notification required. This is not a transfer of a registration.	The same special rule may apply to a qualifying successor to the issuance business. Discontinuance and change notifications should be checked for both sides.	The special rule may apply where the issuance business passes by merger to an entity that was not already an issuer, subject to the statutory conditions.
Prepaid payment instruments (third-party)	The registered issuer remains the same entity. A change in a registered major shareholder or other registered particulars may require notification.	Third-party issuer registration does not transfer. The transferee must itself hold the registration. Transferor discontinuance and successor change filings may also apply.	There is no equivalent succession rule for third-party issuer registration. The successor must be registered before carrying on the business.	The registration does not automatically pass to the survivor. If the registered issuer itself survives, its existing status remains with that same entity.
Cryptoasset exchange service	The registration remains with the target because the registered legal entity does not change. Changes to registered particulars or material business content may require filings.	The legislation expressly addresses a transfer of all or part of the business, including advance public notice, but does not transfer the registration. The transferee must itself be registered.	Succession of all or part of the business through a company split is addressed procedurally, but this is not succession to the registration. The successor must itself be registered.	Where the registered entity survives, its registration remains with it. Where it disappears, the pre-merger procedures apply but the registration does not carry to the survivor.
Electronic payment instruments service	The registration remains with the target if the legal entity itself is unchanged. Changes in officers, business categories, instruments handled, methods or outsourcing may require a change registration or notification.	The legislation contemplates a transfer of all or part of the business and requires related procedures, but contains no rule transferring the registration. A transferee must itself be registered.	Succession through a company split is likewise contemplated, but the statutory procedure concerns the business and user protection, not the registration. The successor must hold the required registration.	If the registered entity survives, its registration remains with the same entity. If it disappears, the merger procedures apply but do not transfer the registration itself.
Money lending	A share acquisition leaves the registrant unchanged, so the registration ordinarily remains in place. Filings may still be required where registered matters change, including directors, offices or business methods.	There is no rule transferring the registration with a business transfer. A transferee that will itself carry on money lending must obtain or already hold the registration. Limited run-off rules are not registration succession.	No statutory rule passes a money-lending registration to a company succeeding to the business through a company split. The successor must itself be registered before carrying on new lending business.	If the registered lender survives, its registration remains with the same entity, subject to any change filings. If it disappears, its registration loses effect; the survivor needs its own registration.

This table is an overview of the questions to be resolved when choosing a structure. It does not set out every filing or procedure that may apply, and the position for a particular service should be confirmed against the applicable legislation and the facts of the transaction.

Resolve the regulatory question before the structure is fixed

The practical consequence is that the regulatory analysis should begin before the transaction structure is fixed. A share deal may leave the registered entity in place, but it can still produce changes that require regulatory filings or affect the basis on which the business is operated. A business transfer, company split or merger may achieve a broader transfer of contracts and operations while leaving a separate question as to whether the entity conducting the regulated activity after closing has the necessary regulatory status.

This distinction also shapes due diligence: the review should establish which entity holds each regulatory status and which entity will conduct each regulated activity after closing. Chapter 5 addresses how that analysis should be carried through into due diligence, the transaction documents and post-closing changes.

Foreign investment screening is a separate layer. A foreign acquirer may need to consider the Foreign Exchange and Foreign Trade Act (FEFTA) even where the target’s sector-specific registration remains with the same legal entity. That framework, together with merger control, is covered in our general guide to acquiring a Japanese business. The chapters below deal instead with the sector-specific regulatory status of the financial business itself.

Funds Transfer Services and Prepaid Payment Instruments

Start with the actual flow of funds

For an acquirer, the first question is not how the target describes its payment service, but what happens to the money in practice. The review should identify who receives funds from the customer, who becomes obliged to the customer or to the intended recipient, when that obligation is discharged, and whether funds move within Japan or across borders. A commercial description such as “payment collection”, “settlement support” or “collection agency” does not by itself determine the regulatory classification, and not every arrangement using those labels is treated in the same way. The contractual allocation of payment obligations is central to the analysis.

This is particularly relevant where the target handles cross-border collections. Certain arrangements commercially described as collection agency services can fall within the funds transfer regime depending on how the payment obligation and the flow of funds are structured. A buyer should therefore test the existing service model rather than assume that a label used in contracts or sales materials settles the position.

Check whether the existing funds transfer model will remain the same

Japan distinguishes different categories of funds transfer business, and the permitted transaction profile and regulatory conditions differ by category. For M&A purposes, the point is not to reproduce those categories in detail, but to ask whether the target’s current registration and operating model will still fit the business after closing. A proposed increase in transaction size, a change in how long customer money is held, the addition of new payment routes, or the transfer of a function to another group entity can each affect that analysis.

Due diligence should also identify the target’s current safeguarding arrangements and consider whether the proposed post-closing service model remains consistent with them. Changes made to treasury, settlement or custody arrangements as part of group integration should not be treated as purely operational if they affect the regulatory model on which the business is conducted.

Identify the issuer and the unused balance for prepaid payment instruments

Prepaid payment instruments require a different analysis. The review should first identify the legal entity that issues the instrument, whether the instrument is used only with the issuer or can be used with third parties, and the amount and treatment of outstanding unused balances. These points affect both the target’s regulatory status and the consequences of moving the issuance business to another entity. The treatment of unused balances and the arrangements for redemption or continued use can also become transaction issues where the issuer will change.

As set out in Chapter 1, Japanese law treats succession differently for self-use and third-party prepaid payment instruments. The transaction structure should therefore be considered before assuming that an issuance business can simply be transferred within the buyer’s group. Where the issuer will remain the same after a share acquisition, the focus shifts to changes in the registered or notified particulars and to whether the post-closing product and distribution model remains within the existing framework.

Review the post-closing payment model, not only the current one

Payment businesses often change quickly after an acquisition. The buyer may wish to centralise settlement, replace payment processors, change the entity contracting with users, introduce a global treasury function or combine the Japanese service with an overseas platform. Each change can alter the legal relationships that supported the target’s existing regulatory classification.

The practical exercise is therefore to set the current and the proposed models side by side. That comparison should show the contracting entities, the movement of money, customer-facing obligations, safeguarding arrangements and material outsourced functions. It can then be used to identify which elements can remain in place and which changes may require a filing, a change to the registered business model or further regulatory analysis before implementation.

Cryptoassets and Electronic Payment Instruments

Identify the regulated activity before focusing on the label

Cryptoassets and electronic payment instruments are not a single regulatory category under Japanese law. A commercial description such as “crypto”, “stablecoin”, “wallet” or “exchange” is therefore only a starting point. For M&A purposes, the review should identify what the target actually does: whether it buys or sells assets, intermediates transactions, holds or manages assets for customers, transfers them, or provides technology or infrastructure to another regulated operator.

The legal entity performing each function matters. A group may use one company for customer contracting, another for custody or asset management, and another for technology or operational support. Due diligence should map those functions against the registrations held by each entity rather than treat the group’s service as a single regulated activity. For electronic payment instruments in particular, the review should identify the instruments actually handled and the target’s role in relation to them, because a post-closing change in the product range or service function can alter the regulatory analysis without any change in the marketing label or the customer interface.

Distinguish a full operator from an intermediary model

The regulatory framework can differ where a business only intermediates specified transactions for a registered principal rather than itself operating the full exchange or electronic payment instrument service. Japan now has a registration framework under which certain limited intermediary activities can be conducted for a registered cryptoasset exchange service provider or electronic payment instruments service provider.

For an acquirer, the important question is whether the target’s actual role fits the regulatory status it relies on, and whether that role will remain limited after closing. If the buyer intends to expand the target from an intermediary model into custody, principal trading, broader exchange functions or another activity, the existing registration should not be assumed to cover the expanded model.

Treat custody and customer assets as transaction issues

The review should identify whether the target or another group entity holds, controls or can move customer assets, and how those assets are segregated or otherwise protected. This affects both regulatory due diligence and post-closing integration. A proposed change to wallet architecture, custody arrangements, access keys, settlement processes or the legal entity performing those functions may change the regulatory analysis even where the customer-facing product is unchanged.

The same applies to outsourcing and systems. Moving functions to an overseas group platform, replacing a service provider or centralising operational access can affect the arrangements on which the regulated service is conducted. The buyer should therefore understand not only the target’s registration but also the operational architecture supporting it.

Compare the registered business with the business actually conducted

A registration certificate is not the end of the inquiry. Due diligence should compare the registered or notified activities with the products actually offered, the assets or instruments handled, the manner in which customer orders are received and executed, and the entity responsible for each regulated function. Regulatory correspondence, past changes to products and any unresolved questions about classification can be relevant to that comparison.

The same analysis should be repeated for the proposed post-closing model. If the buyer plans to add new assets, move custody, change the contracting entity or integrate systems across the group, the resulting registration and filing requirements should be assessed before implementation.

Where legislation affecting the target’s registration framework has been enacted but is not yet fully in force, the parties should also confirm which regime and which transitional provisions will apply at signing, at closing and during the proposed post-closing operation.

Money Lending Businesses

Identify the entity that is conducting the lending business

The starting point is to identify which legal entity is actually conducting the lending business and which entity holds the relevant registration. Ownership of loan receivables and operation of a money lending business are not necessarily the same question. A buyer should therefore distinguish between acquiring a registered lender, acquiring a portfolio of receivables, and moving lending operations to another group company.

This distinction matters when selecting the transaction structure. In a share acquisition, the registered entity remains in place, although changes to registered particulars may require filings. If the lending business itself is to be transferred to another entity through a business transfer, company split or merger, the registration does not automatically pass with the business. The entity that will conduct the regulated activity after the reorganisation must have the necessary regulatory status.

Review the existing loan book as a regulatory asset and liability

Due diligence should not stop at confirming the existence of a registration. The historical loan book can carry regulatory and contractual exposure that remains relevant after closing. The review should therefore consider the terms on which loans were originated and administered, including interest and fee calculations, customer documentation, collection practices, complaints and any identified or potential overpayment or refund exposure. Where due diligence identifies issues in areas such as affordability assessment, required documentation, use of credit information or collection conduct, what matters for the transaction is how those issues affect the existing portfolio, customer remediation, representations and warranties and the post-closing compliance plan, rather than how the underlying rules operate in the abstract.

Outsourcing arrangements can also be material. Servicing, collections, customer communications, credit assessment and systems support may involve third parties or other group entities. The buyer should understand who performs those functions today and whether the same allocation will continue after closing.

Test the proposed post-closing operating model

The post-closing review should identify whether the lending entity, its offices, its directors or other registered particulars will change, and whether the arrangements required for the operation of the lending business will remain in place. This includes the organisation of lending-business managers, where applicable, as well as material changes to servicing, collections, products, outsourcing and systems.

A portfolio acquisition should be distinguished from an acquisition of the lending business itself. Acquiring receivables does not, by itself, answer whether the acquirer will be conducting a regulated money lending business; the activities to be carried on after the acquisition, including servicing and collection arrangements, need to be considered. The transaction documents and the integration plan should therefore reflect the distinction between transferring economic assets and transferring the regulated operating business.

Regulatory Due Diligence, Transaction Documents and Post-Closing Changes

Confirm the regulated business as it is actually operated

Chapters 2 to 4 illustrate why a registration certificate alone is not sufficient. Regulatory due diligence should consolidate those sector-specific findings into a map of each regulated activity, the legal entity performing it, the regulatory status relied on and any material difference between the registered or notified model and the business actually conducted. Any unresolved filing or classification issue that may affect the proposed transaction or the post-closing model should also be identified, including cases where the service has evolved incrementally without a corresponding review of the regulatory position.

The review should also cover regulatory correspondence, past inspections or requests for reports, material incidents, complaints and unresolved filing issues to the extent relevant to the transaction. For payment, cryptoasset, electronic payment instrument and lending businesses, the buyer should understand how customer money or assets are handled, which functions are outsourced, and whether the operational model has changed since the relevant registration or notification was made.

Translate the regulatory findings into the structure and the documents

The findings should be considered together with the proposed deal structure. If the registered entity will remain in place, the focus may be on changes to registered particulars, business methods, officers, outsourcing or products. If regulated operations will move to another entity, the parties should consider registration, discontinuance or succession procedures before that entity can operate the business as intended.

Those issues can affect the transaction documents. Depending on the circumstances, the parties may consider representations and warranties concerning regulatory status and compliance, covenants requiring specified filings or operational steps, conditions to closing where a regulatory step is material to the proposed structure, and the allocation of responsibility for identified historical issues. The drafting should reflect the issue actually found in due diligence rather than assume that the same regulatory protection is required in every financial services acquisition.

Consider whether regulatory consultation is appropriate

Some transactions may benefit from discussion with the Financial Services Agency or the relevant Local Finance Bureau, particularly where the proposed structure involves a new operating entity, a material change to the service model or an issue whose regulatory classification is uncertain. That does not mean that every acquisition calls for a pre-signing or pre-closing consultation.

Whether consultation is appropriate, what should be presented and when the discussion should take place depend on the regulated activity, the issue to be confirmed and the transaction timetable. The parties should also distinguish between a statutory filing or approval requirement and an informal consultation undertaken to clarify how the regulatory framework applies to a proposed model. The transaction timetable should be built around the procedures that are actually required, or considered appropriate, for the case.

Reassess the business when the integration plan changes it

Closing does not end the regulatory work. Post-closing integration can change the facts on which the pre-closing analysis was based. A new product, payment route, outsourcing arrangement, customer-asset structure, system provider or group entity may affect the target’s regulatory position even where the legal entity holding the registration remains the same. The integration plan should therefore identify which changes can be implemented within the existing model and which should be reviewed before implementation.

Where the buyer intends to centralise functions outside Japan or combine the Japanese business with a global platform, sector-specific financial regulation may need to be considered alongside data protection, cybersecurity, foreign investment and other rules.

Frequently Asked Questions

If we buy the shares of a regulated financial company, do we need a new registration?

Not necessarily. In a share acquisition the target company remains the same legal entity, so an existing registration will ordinarily remain with that entity rather than move to the buyer. The acquisition may nevertheless result in changes to officers, offices, business methods, shareholders or other registered matters that require notification or another procedure under the applicable legislation. The position should therefore be checked for the particular regulated service and the post-closing structure, rather than determined solely by the form of the share acquisition.

Can a regulated business be moved to another group company after closing?

Potentially, but the regulatory analysis differs from moving contracts and assets. Operations may be capable of being transferred within the group while the relevant registration does not automatically pass to the transferee. Some financial services regimes also contain specific provisions addressing particular forms of business succession. Before moving the business, the group should identify which entity will conduct each regulated activity afterwards and whether that entity already has, or will require, the relevant regulatory status.

Does a merger or company split automatically carry the regulatory status to the successor?

No general rule allows that assumption. The treatment differs between regulatory regimes and, in some cases, between different forms of regulatory status under the same legislation. A statute may recognise succession to the business, or provide procedures for a merger or company split, without providing that the registration itself automatically passes to the successor. The analysis should therefore identify the surviving or succeeding entity and the specific statutory rules applicable to that service before the corporate reorganisation is implemented.

Do we need to consult the FSA or a Local Finance Bureau before signing or closing?

There is no single answer for every financial services acquisition. Whether consultation is appropriate, and when it should take place, depends on the regulated activity, the transaction structure, the proposed changes and the issues requiring confirmation. A transaction involving a new operating entity, a material change to the service model or an uncertain regulatory classification may raise different considerations from a straightforward share acquisition with limited operational change. The need for consultation should therefore be assessed as part of the transaction timetable rather than assumed in every case.

Can we rely on the seller’s statement that the business is properly registered?

The seller’s position is an important starting point, but regulatory due diligence should ordinarily go further. The review should identify the legal entity holding each registration or notification and compare the registered or notified business with what the target actually does. Funds flows, customer assets, products, outsourcing arrangements, systems, regulatory correspondence and past changes can all be relevant. This can identify not only an absence of registration but also cases in which the business has developed in ways that may require additional filings or regulatory analysis.

Does foreign investment screening apply separately when a foreign investor acquires the regulated company?

It may. Sector-specific financial regulation and Japan’s foreign investment screening regime address different questions. The fact that a target holds the registrations required for its financial business does not determine whether a foreign investor’s acquisition is subject to prior notification, an exemption or post-transaction reporting under the Foreign Exchange and Foreign Trade Act. The analysis depends on matters including the investor, the target’s activities and the transaction. Our general guide, “M&A in Japan for Foreign Acquirers and Investors”, covers the foreign investment framework in more detail.
