The Sentence That Changes the Statute
It took seventy years and a single paragraph.
On August 24, 2026, the Ministry of Justice presented a draft report to the expert body it convened this spring to reexamine Japan's prostitution laws. Inside that draft is the conclusion the country's legal establishment has avoided since 1956: the man who solicits sex should be punishable, and the fine attached to the offense should go up.
The panel is the Study Group on the Regulation of Prostitution — baibaishun ni kakaru kisei no arikata kentōkai — chaired by Kayoko Kitagawa, a criminal-law professor at Waseda University's graduate school. Monday's session was its eighth. The first was held on March 24.
The draft, according to reporting by Asahi Shimbun, NHK, Jiji Press, Mainichi Shimbun and TBS, records that multiple members said the imbalance in the current law needs correcting, and that no member objected to bringing the purchasing side under regulation. The ministry intends to finalize the report in September and is arranging to submit an amendment bill to the extraordinary session of the Diet this autumn.
That timeline is not procedural noise. It means the reform has moved out of the seminar room.
What the Law Says Now
Japan's baishun bōshi-hō — the Anti-Prostitution Act, enacted in 1956 — declares that no person shall sell or buy sex. It attaches no penalty to either act.
The penalties live elsewhere in the statute, and they fall in one direction. Article 5 punishes soliciting for prostitution in public: up to six months' confinement or a fine of up to ¥20,000 — roughly $135 — a figure set in the law's early years and never meaningfully revisited. Articles 6 through 13 escalate against the people around the transaction: procuring, contracting a woman into prostitution, taking the proceeds, advancing money for the purpose, providing the premises, running the business, financing it. Providing premises carries up to seven years. Operating a prostitution business carries up to ten.
Every one of those provisions reaches the seller, the broker, the operator or the financier.
None of them reaches the customer.
The practical result is visible on the pavement. Police in Tokyo's Shinjuku Ward have arrested women in their twenties for waiting for clients around Okubo Park in Kabukicho, and Osaka prefectural police have done the same on the streets of Kita — enforcement this publication has covered repeatedly through the summer. The men who walk up to those women, negotiate a price and walk away have committed no offense at all. Critics in the Diet have called it a distorted structure in which only the woman selling sex gets handcuffed.
The draft report proposes to end that specific asymmetry by writing the buyer into Article 5's solicitation offense.
What Set This in Motion
The review was ordered from the top. Prime Minister Sanae Takaichi instructed the justice minister last November to examine what could be done about the country's lopsided prostitution rules, and the ministry stood up the study group in March.
The cases that gave the instruction its urgency were not abstract. In November of last year, a 12-year-old Thai girl was found to have been made to work at a private-room massage business in Tokyo, taking roughly sixty men in a single month. Asahi has cited that case among the events framing the review. This year has since produced a near-continuous run of prosecutions: soapland managers charged with providing premises, scout networks accused of funneling indebted women into sex work, host clubs investigated over the debts that push them there.
All of those cases enforce the law as written. The panel's question was whether the law as written is the right one.
The Argument Against
The draft did not land unopposed, and the objections do not come only from where one might expect.
Asahi Shimbun published a companion piece the same day reporting concerns that the draft preserves the law's contradictions and infringes sexual freedom. The paper's earlier analysis of the review was headlined, plainly, that opinion on punishing buyers is divided.
The most consistent opposition has come from sex workers themselves. SWASH, the sex worker health and rights group founded in 1999, has argued against criminalizing purchasers on harm-reduction grounds: that where buyers face arrest — France is the example the group returns to — the transaction does not stop, it relocates. Negotiations move to darker streets, screening time collapses because the customer is now the one at legal risk, and the woman absorbs the added danger. SWASH's position is that exploitation should be attacked through working conditions rather than through a broader criminal net.
The counterargument, put to Chūnichi Shimbun by an NPO working the area, is that the asymmetry is itself what has let conditions around Okubo Park deteriorate — that a law which punishes only one party to a transaction is not a neutral law but a subsidy to the other party.
Both claims describe the same street. Neither has been tested in Japan, because Japan has never tried the alternative.
What the Draft Does Not Do
Two things are worth naming.
First, this is not the Nordic model. Sweden and France penalize the buyer while decriminalizing the seller. The draft report, as described in Monday's reporting, adds the buyer to the solicitation offense — it does not remove the seller from it. If enacted in that form, Japan would punish both sides of a street solicitation rather than shifting liability from one to the other. That is the preserved contradiction the critics are pointing at.
Second, the definitional question remains the largest unresolved item on the table. The 1956 act defines prostitution as sexual intercourse with an unspecified person in exchange for compensation. That narrow definition is the reason Japan's licensed adult-entertainment sector — the fūzoku businesses regulated under the fūei-hō, the Businesses Affecting Public Morals Regulation Act — operates lawfully by offering services that stop short of intercourse. Panel members have acknowledged that views on how to treat acts "similar to intercourse" vary widely and that consensus would be hard to reach. Nothing in Monday's reporting suggests they found one.
So the reform now heading toward the Diet is narrower than its framing implies. It is aimed at the street, not at the industry.
What Happens Next
The study group will take the draft back, and the ministry expects a finished report in September. From there it becomes a bill, and the bill goes to the extraordinary Diet session this autumn — an aggressive schedule for a statute untouched in its essentials for seven decades.
Whether it survives contact with the legislature is a separate question. Punishing sex buyers polls well in the abstract and gets complicated in committee, and the groups most affected by the change are among those most opposed to it.
But the record now shows a government panel, on August 24, 2026, receiving a document that says the men should be punishable too — with no member dissenting. Seventy years of legislative silence on that point ended in an afternoon's paperwork.
