First, the conclusion

The lack of adult content companies cannot be explained by any of the following: `They can't be listed because they're illegal,'' ESG investors uniformly reject all companies,'' or `They're too profitable and don't need capital.''

The TSE's listing review is not a mechanism to exclude specific industries by name, but rather to check the soundness of corporate management, internal control system, appropriateness of disclosure, public interest and investor protection. There is also a path to listing for businesses aimed at adults. However, after putting in place a management system that can withstand such scrutiny, companies must continue to deal with payment terms, rights of performers and creators, content reviews, deletion requests, and credit judgments from business partners even after listing.

What is more difficult is profitability than whether or not a company can be listed. Despite the advantages of listing, including the ability to raise funds, creditworthiness, recruitment, and stock as a currency for M&A, the costs of management and disclosure and the decline in management freedom are significant. If a company is led by its founder and can generate cash, it may be more rational to remain private and use bank loans, private placements, or business sales.

How true is “almost no listed companies”?

I want to be a little more careful here.

The TSE industry classification is 33 industries, and there is no separate category called adult content. Because they are divided into video distribution, e-books, EC, advertising, payment, etc., it is impossible to count how many specialized companies there are just by looking at the list of exchanges. It is also difficult to confirm official statistics that use the same definition for the domestic market, including videos, two-dimensional content, doujinshi, merchandise sales, and in-store services.

Therefore, strictly speaking, it cannot be said that there are no specialized listed companies even though the market size is several hundred billion yen. As of July 30, 2026, it is more accurate to say that it is extremely difficult to find a domestic listed company that clearly states to investors that its main business is adult care and can track its individual performance.

DMM.com is known for its diverse services, including those for adults, but it is operated by a limited liability company and not a listed company. However, the capital relationship between DMM.com and other content companies may change over time. Current group relationships should not be determined solely based on the proximity of brand names.

What prevents listing is not the industry but the “cost of proof”

Can rights processing be tracked on a transaction-by-transaction basis?

Even if you say it's for adults, there are different risks when it comes to live-action video, manga, audio, games, and live streaming. For live-action movies, the focus is on the age of performers, identity verification, contracts, consent, scope of disclosure, and responses to deletion requests. Manga and games have to deal with copyrights, permission for derivative works, illegal uploads, and expression regulations.

In Japan, there is a law that stipulates the contract, performance, publication, cancellation, and injunction regarding contracts for appearing in sex video productions. This law does not criminalize the industry as a whole, but rather requires strict procedures in the production and publication process.

In preparation for listing, the question is not only whether there are rules that describe policies. Who has the rights to a large number of works, when to obtain consent, and which works can be stopped if a problem arises? You will need a trail that can be followed by an audit. The operating costs increase as the number of works and contributors increases.

Payment company rules become de facto conditions for entry

Card payments are not just a means of depositing money. Visa is requiring acquirers to strengthen their control over some legally operated businesses, such as adult-oriented sites, as the risk of illegal activities is relatively high. Mastercard's rules for merchants also include verifying identity, age, and consent, monitoring violating content, and responding to complaints and removal requests.

Here is a common misconception in first drafts. Being unlisted does not mean you can avoid card regulations. Regardless of whether they are listed or unlisted, as long as they use an international credit card network, member stores and payment providers will follow the rules. Moving to crypto assets and independent payments does not necessarily bring freedom; it also creates other burdens such as user convenience, money laundering measures, price fluctuations, and accounting procedures.

For public companies, suspension of payments has a direct impact on business performance and stock prices. Dependence on sales by payment method, chargebacks, continuity of merchant contracts, and rate of transition to alternative payments are essentially very important KPIs. However, not many companies disclose such detailed numbers. The market tends to place discount rates in invisible areas.

ESG and reputation are not “total exclusion”

It would also be foolish to treat adult-oriented businesses as a uniformly sinful stock, in the same way as tobacco or gambling. ESG management policies vary by fund, and some investors do not automatically exclude adult investors.

However, it works in the direction of narrowing the population of investable funds. FTSE Russell's Sustainable Investment Index series includes product exclusions, some of which include adult entertainment. This does not mean that not all institutional investors can buy, but it does indicate that there is room to deviate from ESG index-linked funds and specific mandates.

The other decision is on the business company's side. Advertisers, financial institutions, cloud app distributors, job candidates, and M&A partner companies each have their own brand standards. Even if it is legally appropriate, if the partner does not like the cost of explanation, it will be difficult for business negotiations to proceed. The stronger the connection between a company's name and its business appears through listing, the more likely this friction will surface.

As a result, strong sales growth does not necessarily mean higher valuation multiples. Given the narrowness of the investor base, the tail risk of settlement suspension, and fluctuations in legal costs, there are situations in which governance discounts are more important than scarcity premiums.

Information disclosure is not a weakness, it changes the business model

Securities reports continuously disclose business details, risks, major contracts, financial information, etc. The Tokyo Stock Exchange also places appropriate disclosure of company information as a listing screening item.

The problem for adult-oriented businesses is not the embarrassment of having their business "glassed out." Management accounting that explains revenue sources, a ledger for rights processing, screening of outsourcing companies, and reporting channels in the event of an accident need to be rebuilt to the standards of a listed company.

For example, even if sales of a doujin sales platform are increasing, it is difficult to assess the sustainability of profits unless you can track the number of complaints of rights infringement, the time it takes to remove rights, the concentration on top creators, and the bias in payment methods. What we want in a public market is not a story of market size, but a mechanism that can generate repeatable profits and limit losses in the event of an accident.

“There is no need for listing because the profits are high” is only half correct

Digital distribution does not require a factory, and the inventory burden is lighter than physical distribution. There are cases where successful platforms tend to accumulate internal funds and there is little reason to rush to raise money from the stock market.

However, business for adults does not necessarily have high profit margins. There are costs involved in original production, copyright processing, payment fees, advertising, identity verification, moderation, legal affairs, refunds, and measures against illegal reproduction. With submission-based services, the larger the scale, the greater the review burden.

Still, some companies choose not to go public, not because they don't need the funds, but because they can raise the necessary funds while remaining private. Options include bank loans, owner funds, alliances with operating companies, private equity, and business sales. If growth investments can be covered by these, there is less reason to take on the costs of dealing with shareholders and going public.

Why can you list on a comprehensive platform?

What appears to be the reality for domestic listed companies is that they handle age-restricted works as part of their comprehensive services, rather than exclusively targeting adults.

U-NEXT HOLDINGS (9418) is a TSE Prime company in the information and communications industry, and in addition to content distribution, the company operates multiple businesses including store and facility solutions, communications and energy. U-NEXT's official help page shows how to manage R18+ works and age-restricted content, but the business unit for investors is "content distribution."

This shape has three advantages.

  • Don't rely solely on adult content for your brand and revenue
  • Can use common member authentication, billing, distribution platform, and parental management
  • Investors can evaluate the company's overall recurring charges, ARPU, content costs, and profit margins

However, it cannot be read from this that ``growth of the adult market = growth of U-NEXT HOLDINGS' profits''. If sales and profits for adults are not disclosed individually, the degree of contribution will not be known, and other factors such as general works, sports, anime, and store DX can have a greater impact on business results.

KPIs that investors should look at

Membership alone is not enough when evaluating platforms that include adult content.

IssuesKPIs to checkWhat they mean in the stock market
MonetizationPaid members, ARPU, cancellation rate, purchase frequencyIs the increase in users leading to profits
ContentWork procurement costs, gross profit margin, and concentration on top rights holdersMeasuring hit dependence and bargaining power
PaymentComposition by payment method, approval rate, refund/chargebackMeasuring the downside when payments are suspended
Rights/SafetyIdentity/age verification rate, number of complaints, deletion timeCan legal/brand accidents be limited
Attracting customersAdvertising costs, cost per customer acquisition, payback periodCan you grow even under advertising restrictions
CashOperating CF, advances received, content investment, working capitalAre accounting profits converted into cash

In reality, only a limited number of these figures are disclosed. That is why simply labeling comprehensive companies that do not disclose sales to adults as ``hidden adult-related stocks'' is a weak investment hypothesis. Themes that cannot be measured tend to be conveniently explained away after stock prices move.

Scenarios where the number of listed companies increases and scenarios where they do not increase

Increasing scenarios

If rights and consent information can be standardized, and identity verification, content monitoring, and deletion responses can be performed in an auditable manner, the cost of listing examinations and providing explanations to credit card companies will be reduced. It will also be easier for companies to go public that expand their business into the creator economy, including areas other than those aimed at adults, and diversify their revenue sources and brands.

Additionally, if a company emerges that wants to use its stock for large-scale M&A or overseas expansion, the opportunity cost of remaining private will rise. For the first time, public market funds and credit outweigh administrative costs.

No increase scenario

If payment screening, age verification, and protection against copyright infringement become more stringent, and restrictions on advertising and app distribution expand, fixed costs and accident response costs will increase faster than sales growth. If investors place a constant valuation discount on sales to adults, the price at the time of IPO will be unlikely to meet management's expectations.

As long as there is a sufficient funding environment for private companies and founders place importance on voting rights and business flexibility, the number of listed companies will be difficult to increase. Having a large market and being suitable for publicly traded stocks are two different things.

[Summary]

The reason there are so few adult content companies in the domestic stock market is not simply social prejudice.

We will manage rights, consent, and age verification on a work-by-work basis, promptly stop problematic works in accordance with the payment company's rules, and continue to disclose them as a listed company. After that, it is necessary to explain the sustainability of the business to investors, financial institutions, and business partners. Even for legitimate businesses, the cost of proving this is not trivial.

And the biggest thing is that you can continue your business even if you don't go public. Managers don't have to give up their freedom if they can grow with internal funds or the private market.

For investors, it is better to look at a comprehensive platform's payment resistance, rights management, ARPU, churn rate, content investment, and cash generation ability, rather than looking for rare specialized stocks. The size of the adult market is just the beginning. What determines the value of a stock is whether it can convert that demand into auditable profits.
