[For International Readers] How Japan's 2025 Law Reform Is Transforming Its Nightlife: The Decline of Traditional Adult Venues and the Women Going "Underground"

Japan's nightlife and adult industry (sex work) has built its own complex ecosystem over many years. But with the amendment to the Act on Control and Improvement of Amusement Business, etc. (the Amusement Business Act, or Fueiho) that took effect on June 28, 2025 (National Police Agency enforcement notice, PDF in Japanese), that structure has reached a historic turning point.

For international readers who want to understand the realities of Japan's adult industry and nightlife, this article explains the "surface clean-up" brought about by the reform and the "invisible move underground" taking place behind it.

1. The Core of the June 2025 Reform: Bans on "Romance-Based Sales" and "Scout-Back" Payments

The businesses hit hardest by the reform were hospitality venues with hostessing, such as host clubs and cabaret clubs, and the sex industry that was closely tied to them.

In recent years, "iro-koi eigyo" (romance-based sales, or fake romance) at Japanese host clubs had become a serious social problem: hosts made female customers feel pseudo-romantic attachment and pushed them into paying huge bills. Women who ran up large debts to boost a host's sales kept ending up working in sex businesses to repay them. The reform explicitly banned this kind of predatory romance-based sales for the first time.

What shook the structure of the adult industry even more fundamentally was the complete ban on "scout-back" payments.
Until now, Japan had a distinctive practice (scout-back) in which a shop kept paying a host or an unscrupulous scout who introduced a woman to the shop a "referral fee" taken from part of her earnings, on an ongoing basis. This system, which preyed on women, has now been clearly prohibited by law.

2. Why Did Japan's Adult Shops Rely on "Scouts"?

You may wonder: "Why didn't the shops simply post their own job ads instead of relying on scouts?"

Prostitution is prohibited under Japanese law (the Prostitution Prevention Act). Fashion Health and Delivery Health shops operate after filing a notification under the Amusement Business Act as businesses that do not provide intercourse, while soaplands have operated in a legal gray zone under the fiction that "whatever happens in a private room is free romance between two individuals." Because of the nature of these businesses, it is said to be hard for them to advertise in mainstream job media, which limited how far shops could recruit women on their own.

So many shops came to depend on networks of professional "scouts," who approach women on the street or on social media, and of "hosts," who send their female customers into the sex industry to collect their debts. These people kept supplying women, and that is how many shops were able to operate. With the ban on scout-back payments, this supply network has been badly shaken.

3. The Shock of 2026: The Simultaneous Closure of a Major Soapland Group and Fewer Places to Work

The reform and stronger police enforcement quickly redrew the industry's map. The structure of the industry has changed significantly, and some point out that fewer women now work at traditional store-based adult venues.

As recruiting through scouts has become harder, it is said that even some major soaplands and Delivery Health shops now have fewer women on their rosters.

A symbolic event came on the night of January 30, 2026, when the "Marine Group," which ran 21 soaplands across Japan, closed every one of its shops at once. The reason given to its cast members was "financial difficulties" (FRIDAY Digital, in Japanese). However, two days earlier, on January 28, police had searched one of its affiliated shops in Sendai, "Marine Senhime" (tbc Tohoku Broadcasting, in Japanese). No causal link to the closures has been established, but executives of that shop's operating company were later arrested on suspicion of violating the Prostitution Prevention Act by providing premises for prostitution (coki, in Japanese). (See also: why a 43-year-old Yoshiwara soapland closed its doors.)

On the positive side, some women who had been forced to work have been freed. On the other hand, the reality is that the very places where women can work, the well-known traditional shops with thorough safety management, are on the decline.

4. Where Did the Women Go? The Reality of the Invisible Move "Underground"

So has the total number of women working in Japan's sex industry gone down? The answer is "no."
Some point out that the overall number of women has not fallen; they have "simply scattered to places beyond the reach of the police and the law."

Women who must earn money to make a living are moving into new forms of work such as the following, diversifying how they earn.

• Person-to-person deals via social media and apps (C2C): "papa-katsu" and individual prostitution, where women negotiate directly with clients through social media or dating apps without belonging to a shop. Earning one job at a time, like gig work, is said to be on the rise.
• Working abroad (Dekasegi): It has been reported that more Japanese women are traveling to the United States, Australia and other Asian countries to earn foreign currency more efficiently, and groups that arranged such trips have been busted (Nikkei, in Japanese).
• Moving to online streaming: Some women avoid the risks of physical contact and make a living from live streaming or selling digital content.

Summary

The 2025 reform was a major step toward eliminating predatory host-club debt and scouting. As a side effect, however, Japan's adult industry is shifting from a "managed, store-based" model to a "lawless, individual and underground" one. Even as the streets look cleaner on the surface, a more complex and dangerous reality is spreading below it.

Frequently Asked Questions (FAQ for International Readers)

Q1. Are Japan's adult venues such as "soaplands" legal in the first place?

A. Soapland shops themselves operate under a licence based on the Public Bath House Act and a notification based on the Amusement Business Act, so the shops themselves exist legally. On the other hand, Japanese law (the Prostitution Prevention Act) prohibits sexual intercourse in exchange for money. Soaplands have long been tolerated as a gray zone under the fiction that "whatever happens in a private room is free romance between a customer and an employee." However, legal interpretation and enforcement can change. Other types of venues, such as Fashion Health and Delivery Health, operate after filing a notification as businesses that do not provide intercourse.

Q2. Is "papa-katsu," mentioned in the article, the same as prostitution?

A. Papa-katsu originally spread as a term for "having meals or going on dates with financially well-off men in exchange for financial support (pocket money)," similar to finding a sugar daddy. Some cases involve no physical relationship, but in practice it is very often used as a euphemism for individual prostitution arranged through social media.

Q3. What is "Tokuryu"? Is it different from the yakuza?

A. It is short for "anonymous and fluid crime group" (tokumei ryudo-gata hanzai group). Unlike the traditional yakuza (organized crime groups), it has no clear organizational chart. It recruits disposable operatives through social media using anonymous messaging apps such as Telegram, and carries out fraud, arranging prostitution, robbery and more. It is a new type of criminal organization that is hard to pin down, and it has become a major social problem in Japan today.

Q4. Why is the move "underground" dangerous for the women who work in the sex industry?

A. Well-known traditional shops had a certain "safety net": the shop would ban troublesome customers, guarantee women's pay and sometimes even protect them from organized crime. In person-to-person deals or environments involving underground groups, women find it hard to ask the police for help even if they suffer violence, hidden-camera filming or unpaid fees from clients, which leaves them in a very dangerous position.
