“Can I smoke a cigarette at a hookah bar?” “Is heated tobacco allowed indoors?” “What about my vape?” If you smoke cigarettes or use heated tobacco, these are natural questions before visiting a hookah lounge in Japan.
Here’s the short answer: whether you can use cigarettes, heated tobacco or e-cigarettes at a hookah bar depends on each venue’s rules. Under Japanese law there are several types of room where smoking is allowed, and what you can smoke and what else you can do there changes with the type of room. On top of that, venues often set rules of their own. So you can’t assume that “it’s a hookah bar, so cigarettes must be fine.”
This guide explains how smoking rooms work under Japan’s revised Health Promotion Act, based on Ministry of Health, Labour and Welfare information, then covers what to check, etiquette and the rules for under-20s. It can’t tell you which legal category any particular venue falls into, so always check the actual rules with the venue.
The short answer: it depends on the venue
- Whether you can smoke cigarettes, heated tobacco or e-cigarettes differs from venue to venue.
- Under Japan’s revised Health Promotion Act, there are several types of smoking room, and what you can smoke and what you can do differs by type.
- Even within one venue, the rules indoors and on a terrace, for example, may not be the same.
- If in doubt, ask the staff before you light up or switch on a device.
- Under-20s may not enter any type of smoking room.
How cigarettes, heated tobacco, vapes and hookah differ
First, a quick look at how each product works.
| How it works | Heat source | |
|---|---|---|
| Cigarettes | Tobacco leaf is burned | Flame |
| Heated tobacco | Tobacco is heated without burning | Electricity |
| E-cigarettes (vapes) | A liquid containing flavorings and other ingredients is heated electrically and the vapor inhaled | Electricity |
| Hookah (shisha) | Tobacco (or a substitute) is heated by charcoal and the smoke drawn through water | Charcoal |
The Ministry of Health, Labour and Welfare’s e-healthnet describes e-cigarettes as products that electrically heat a solution containing flavorings and other ingredients, producing an aerosol (vapor) that is inhaled. The big difference from heated tobacco is that e-cigarettes don’t use tobacco leaf.
Japan’s National Tax Agency also excludes tobacco made for smoking in a water pipe from its definition of heated tobacco under the tobacco tax law. In other words, hookah tobacco is not classed as heated tobacco for tax purposes. The idea that “hookah is just heated tobacco without the electricity” is a misconception.

Japan’s Health Promotion Act: types of smoking room
Since April 2020, indoor smoking is banned in principle
Japan’s revised Health Promotion Act took full effect on 1 April 2020. Under it, the indoor spaces of facilities used by many people became non-smoking in principle, and smoking is allowed only in designated smoking rooms (Ministry of Health, Labour and Welfare). For travelers, the practical point is simple: in Japan you can’t assume that you can smoke indoors, and places where you can are marked by a sign at the entrance.
The law sets out several types of room where smoking is allowed. For understanding the rules at a hookah bar, these are the three to know:
| Type of room | What can be smoked | Food, drink, etc. |
|---|---|---|
| Smoking room | Smoking is allowed | No eating or drinking |
| Heated-tobacco-only smoking room | Heated tobacco only | Food, drink and other services can be provided |
| Smoking-purpose room | Smoking is allowed (set up in a facility whose purpose is smoking) | Staple meals cannot be served |
What you can smoke depends on the type of room
As the table shows, “a room where you can smoke” isn’t one thing: the rules depend on its type. A heated-tobacco-only smoking room, as the name says, is a room where only heated tobacco may be used. A smoking room allows smoking, but you can’t eat or drink inside it.
Which type applies inside a hookah bar depends on the venue’s facilities and how it operates, and you can’t tell from outside. That’s why it’s important not to assume that “if hookah is allowed, cigarettes must be allowed in the same way.”
What “tobacco” and “smoking” mean under the law
Under the Health Promotion Act, “tobacco” includes not only manufactured tobacco but also “manufactured tobacco substitutes.” “Smoking” means burning or heating tobacco to produce smoke, including vapor (e-Gov Law Search).
The sign at the entrance is a useful clue
The Health Promotion Act requires a sign at the entrance of a smoking room stating that entry by anyone under 20 is prohibited (Article 33, paragraph 2 and Article 35, paragraph 2). So the sign at a venue’s entrance is a clue that smoking is allowed there. The sign alone may not tell you whether cigarettes or e-cigarettes can be used, though, so check the details with the staff.
What to check for cigarettes, heated tobacco and vapes
Cigarettes
Cigarettes are smoked by burning tobacco leaf. At some hookah bars you can smoke cigarettes indoors; at others you can’t, or you can only smoke them in a designated place such as a terrace. How a terrace is treated also depends on how the venue has set up its smoking areas. If you want to smoke, always ask the staff before you light up.
Heated tobacco
Heated tobacco is heated electrically rather than burned, and its components are inhaled. As mentioned above, the law has a category called the heated-tobacco-only smoking room, so some venues do allow heated tobacco indoors. But this, too, is a venue rule. Check before you use it.
Public bodies do not describe heated tobacco as safe. Japan’s National Cancer Center says heated tobacco smoke contains harmful substances such as nicotine and carcinogens, and that there is concern about its health effects. A Ministry of Health, Labour and Welfare document notes that some products contain as much nicotine as cigarettes. e-healthnet also says it has been reported that people nearby are exposed to harmful substances.
E-cigarettes (vapes) and “e-hookah”
E-cigarettes heat a liquid electrically and the vapor is inhaled; they are sometimes sold as “e-hookah” or “electronic shisha.” Whether you can vape at a hookah venue also varies from venue to venue. Ask the staff before you use one.
e-healthnet notes reports that some e-cigarettes, with or without nicotine, produce carcinogens such as formaldehyde and acetaldehyde. The U.S. Centers for Disease Control and Prevention (CDC) also says that no tobacco products, including e-cigarettes, are safe. For how e-hookah differs from the real thing, see E-Hookah vs Hookah.
Etiquette when smoking alongside hookah
Even when the rules allow it, be considerate of the people sharing the space.
Mind the smells and smoke
Hookah is about enjoying the aroma of the flavor. Some people don’t like the smell of cigarettes or heated tobacco mixing with their hookah. Pay attention to the people at the next table, not just your own.
Ask the people you’re with
Not everyone in your group may smoke. A quick “Do you mind if I smoke?” before using cigarettes, heated tobacco or a vape keeps everyone comfortable.
Smoke affects the people around you too
According to the CDC, secondhand hookah smoke contains smoke from the tobacco as well as from the heat source, such as charcoal. In a Tokyo Metropolitan Government survey, 22.2% of people who had been in the same space as someone smoking a water pipe said they had experiences such as feeling unwell. The Tokyo Metropolitan Government also warns that in an enclosed space, there is a risk of carbon monoxide poisoning not only for the person smoking but for the people around them.
Smoking cigarettes or heated tobacco on top of hookah means more exposure to smoke and harmful substances. If you feel a headache, dizziness or nausea, stop smoking right away and move somewhere with fresh air. Symptoms and what to do are covered in Why Hookah Can Make You Feel Sick.
Under-20s cannot enter smoking areas
- In Japan, smoking by anyone under 20 is prohibited by law (the Act on the Prohibition of Smoking by Persons Under Twenty Years of Age).
- The manager of a facility with a smoking room or smoking-purpose room must not allow anyone under 20 to enter it (Health Promotion Act, Article 33, paragraph 5 and Article 35, paragraph 7).
- The Ministry of Health, Labour and Welfare says entry by under-20s is prohibited in every type of smoking room, including heated-tobacco-only rooms.
- Under-20s may not enter smoking areas at all, even if they don’t intend to smoke, and this applies to employees as well as customers (Ministry of Health, Labour and Welfare).
So “I won’t smoke” or “it’s a heated-tobacco-only room” doesn’t change anything: under-20s can’t enter smoking areas. Being with a parent or someone over 20 makes no difference either. For age limits and ID, see Hookah Age Limit in Japan, and for families, Can Kids Go to a Hookah Bar in Japan?.
