MIRAI TOKYO concierge team
You are in Tokyo, you have seen that adult services openly exist, and you have also read that prostitution is illegal in Japan. So if you book a companion to your hotel room tonight, are you breaking the law?
The short answer: booking a delivery health (deriheru) service is not a crime. Deriheru is a legal, regulated business in Japan. But honban—full intercourse—is illegal, and that includes at a deriheru. Paying for intercourse is prostitution under Japanese law, whatever the setting and however it is arranged. Beyond that, what can get you into serious trouble is anything involving someone under 18, forcing or pressuring someone, filming without consent, or drugs. At MIRAI TOKYO, the no-intercourse rule is not left to interpretation: it is written into our published rules, in English.
Am I Breaking the Law If I Book a Companion?
No. Booking a companion from a delivery health service to your hotel room is not a crime in Japan. You are using a type of adult business that Japanese law recognizes and regulates.
The confusion comes from the word “prostitution.” In Japanese law it has a narrow meaning: paid intercourse with an unspecified partner. The Anti-Prostitution Act prohibits that, but it does not punish the buyer or the seller for the act itself. Its penalties are aimed at the people around it—those who solicit on the street, arrange it, provide a place for it, or run it as a business.
That does not make paid intercourse a loophole you can use. “Not punished” is not the same as “legal.” Which brings us to the question most visitors actually have.
Is Honban Illegal at a Deriheru?
Yes. Honban (本番, literally “the real thing”) is the Japanese industry word for full intercourse—penetrative, vaginal sex. In English it is often called “full service.” Everything else a deriheru provides is sexual contact that stops short of it. Under current law, those other acts are not “prostitution”—the definition covers intercourse only, and the 2026 review left widening that definition for further consideration.
The line matters because it is exactly where Japanese law draws its own. The Anti-Prostitution Act defines prostitution as intercourse in exchange for payment, and prohibits it. So honban for money is prostitution, and it does not become legal because it happens in a hotel room, with a companion from a regulated business, or as a private “extra” agreed on the spot. A tip, a separate payment, or a quiet “just between us” changes nothing.
- For the shop: a business that offers, arranges or allows honban is no longer operating within the law. Arranging prostitution, providing a place for it and running it as a business all carry criminal penalties.
- For the companion: she is placed in a position the law prohibits, and the business she works for is put at risk.
- For you: the Act does not set a penalty for the customer in a single transaction, but the act is still prohibited. As the Justice Ministry’s 2026 review report put it, selling and buying are illegal acts banned by law even though neither is punished. Other laws can also come into play depending on the circumstances. It is not a gray area to test.
That is why a legitimate deriheru states the rule plainly rather than leaving it to hints. MIRAI TOKYO’s English How to Use page lists “NO FULL SERVICE” among its rules, and its Japanese pricing and system page states that if a guest negotiates for or pressures a companion toward intercourse, the service is ended and no refund is given. For you, a rule this clear is reassuring: you know in advance what your time includes, and there is nothing to negotiate in the room.
Is Delivery Health Really Legal?
Yes. Delivery health is regulated under a different law from the Anti-Prostitution Act: Japan’s adult-entertainment business law, known as Fūeihō. It sets out a “non-storefront” category in which a companion is sent, at the customer’s request, to a home or hotel to provide sexual-contact services. Intercourse is not part of it: paid intercourse would be prostitution, which a different law prohibits. Businesses in this category operate after filing a notification with the local Public Safety Commission, which oversees the police.
That is why deriheru can advertise openly while prostitution remains illegal: they are two different things under two different laws. What a service includes matters far more than whether an English listing calls it “outcall” or “escort.”
Where MIRAI TOKYO fits
MIRAI TOKYO is a delivery health service based in Roppongi, operating in this non-storefront category. There is no shop or lounge to visit. A companion comes to the room where you are staying, at luxury hotels in Roppongi, Ginza, Shibuya, Akasaka and elsewhere in central Tokyo.
Every booking follows the same published rules, at every rank: the service is sexual contact without honban.

What Would Make It Illegal?
For a visitor, the real legal risks are not about booking a regulated service. They come from what happens around it. Keep these in mind:
- Anyone under 18. Paying for sexual activity with a person under 18 is a serious crime in Japan, for the customer as well. A legitimate business confirms the age of everyone it works with; at MIRAI TOKYO, every companion is confirmed to be 20 or older.
- Force or pressure. Sexual acts without the other person’s free consent are a crime, whether or not money has changed hands. Paying for a service never obliges a companion to agree to anything.
- Filming without consent. Secretly photographing or recording someone in a sexual situation is a crime in Japan.
- Drugs. Japan’s drug laws are strict, and possession or use can lead to arrest and deportation.
- Honban. As explained above, paid intercourse is prostitution and is illegal, at a deriheru as anywhere else. At MIRAI TOKYO, negotiating for it or pressuring a companion ends the booking without a refund.
One more practical point: soliciting customers on the street for adult services is banned under Tokyo’s nuisance-prevention ordinance, and what street touts offer is hard to verify. Booking a business that publishes its terms, in a language you can read, is the safer path.
Will the 2026 Law Review Change This?
Not yet. In 2026 the Ministry of Justice reviewed the rules on prostitution, and you may see headlines about “punishing buyers.” Here is what that means for you.
- The likely change: the review report (September 17, 2026) supported introducing rules against buyers soliciting sex, for example approaching people on the street or through social media. The details were left open.
- Not agreed: punishing the purchase itself, or widening the definition of prostitution, was left for careful further consideration.
- Where things stand: as of October 27, 2026, no amendment had been submitted to the Diet. When asked on October 6 about bills for the Diet session that had just opened, the Justice Minister described an amendment as still under consideration. This could change during the session.
Even if a new rule is passed, it would apply only from its start date, and none of these proposals would make booking a regulated delivery health service a crime. A proposal under discussion is not the rule that applies to you today.
Booking MIRAI TOKYO: What Is Included
You do not need to know Japanese law to book with peace of mind. What you need is a business that tells you, in a language you read, what it offers. MIRAI TOKYO keeps its terms public in English: how booking works and the rules of the service on the How to Use page, and the rank-based rates—SILVER, GOLD, PLATINUM and DIAMOND—on the Pricing page. A higher rank changes who you meet, not what the service includes.
If anything is unclear, ask before you book. Our English-speaking concierge answers questions by LINE, WhatsApp, WeChat, Instagram, KakaoTalk or the English web form, during business hours from 10:00 until 06:00. Booking two to three hours ahead is recommended, and same-day requests can be discussed. Many of our guests are Japanese; visitors from abroad are welcomed in exactly the same way.
