Japan has some of the most unusual smoking rules in the world. Indoor smoking is banned almost everywhere, yet you will find beautifully maintained glass-walled smoking booths on street corners. Heated tobacco devices (IQOS, PloomTECH) are far more common than cigarettes. And walking while smoking can get you a ¥2,000 fine on the spot.
Whether you smoke or you are simply curious why everyone seems to be ducking into glass boxes, here is everything you need to know.
Smoking age: 20 years old (not 18). Street smoking: illegal in most city centers. Indoor smoking: banned in virtually all restaurants, bars, and public buildings since 2020.
1. Smoking Age in Japan: 20, Not 18
The Minors' Smoking Prohibition Act (未成年者喫煙禁止法) sets the minimum age for purchasing or using tobacco at 20 years old. This was deliberately kept at 20 when Japan lowered its general age of adulthood to 18 in April 2022. A shopkeeper who sells tobacco to someone under 20 can be fined up to ¥500,000.
Buying Cigarettes Without a Taspo Card
Japan's tobacco vending machines require a Taspo card — a Japanese IC card registered to an adult — to purchase cigarettes. Tourists cannot obtain one. Your only option is to buy cigarettes at a convenience store counter. Point to the numbered cigarette boxes displayed behind the cashier, or show a photo of the pack you want. The staff will not ask for ID in most cases, but are required to refuse sale if you appear to be under 20.
- Mevius (メビウス) — Japan's best-selling cigarette, formerly Mild Seven. Smooth and mild.
- Seven Stars (セブンスター) — Stronger, full-bodied. A classic Japanese brand.
- Marlboro / Camel — International brands are available at most convenience stores.
- Price: ¥580–¥680 per pack (20 cigarettes)
2. Heated Tobacco Devices: Japan's Smoking Revolution
Japan is one of the world's largest markets for heated tobacco products (HTP). You will see far more people using IQOS, PloomTECH, or glo than traditional cigarettes in most cities.
| Device | Brand | Notes |
|---|---|---|
| IQOS | Philip Morris | Most popular. Uses Heets sticks. Available at dedicated IQOS stores and convenience stores. |
| PloomTECH / Ploom X | JT (Japan Tobacco) | Japanese domestic brand. Low odor, popular among younger users. |
| glo | BAT | Uses Neo sticks. Less common but growing. |
3. Outdoor Smoking: Where It Is and Isn't Allowed
This is where Japan confuses most visitors. The key rule is: smoking while walking outdoors is banned in most city centers. Each ward and municipality sets its own ordinance, but major tourist areas enforce this strictly.
| Area | Outdoor Smoking Rule | Fine |
|---|---|---|
| Shinjuku (Tokyo) | Banned except in designated areas | ¥2,000 |
| Shibuya (Tokyo) | Banned in public streets | ¥2,000 |
| Asakusa / Ueno (Tokyo) | Banned on main streets | ¥2,000 |
| Dotombori (Osaka) | Banned on main tourist streets | ¥1,000 |
| Gion (Kyoto) | Banned in historic district | ¥1,000 |
| Designated smoking spots | Fully permitted | — |
| Private property (with permission) | Generally permitted | — |
Finding Designated Smoking Areas
Designated smoking areas (喫煙所 / きつえんじょ / Kitsuen-jo) are found:
- Near train station exits (look for the glass-walled booths with ventilation)
- On certain street corners marked with 🚬 signs on the pavement
- In dedicated sections of parks (not all parks)
- In smoking rooms inside shopping malls and office buildings
The free app Google Maps now shows "smoking areas" when you search in Japanese cities. The Japanese company app Tabelog also flags restaurants with smoking rooms.
4. Indoor Smoking: The 2020 Ban
Japan's Revised Health Promotion Act took full effect on April 1, 2020, making indoor smoking illegal in virtually all public places. This includes:
- Restaurants and cafés with staff (even if small)
- Bars and izakayas that employ workers
- Hotels (common areas — rooms vary by property)
- Airports, train stations, shopping centers
- All government buildings, hospitals, schools
- Bars/restaurants established before April 2020 with fewer than ¥100 million capital and operated by the owner alone (family business exemption) — must display a designated notice
- Hotel rooms designated as smoking rooms
- Pachinko parlors (can have designated indoor smoking areas under transitional rules — but this is becoming increasingly rare)
In practice, if you are in a tourist area in Tokyo, Osaka, or Kyoto, assume all restaurants and bars are non-smoking unless a large 🚬 notice is visible at the entrance.
5. Hotels and Ryokan
Most chain hotels in Japan are entirely non-smoking. If you smoke, request a smoking room (喫煙室 / kitsuenshitsu) when booking. Availability is limited, especially in Western-style business hotels — many have converted entirely to non-smoking.
Traditional ryokan (Japanese inns) typically allow smoking only on balconies or in designated outdoor areas. Ask when checking in. If you smoke in a non-smoking room, hotels charge a deep-cleaning fee of ¥20,000–¥50,000.
Conclusion
Japan's smoking rules are strict but clear: stay out of designated non-smoking areas, use the glass smoking booths near stations, and never light up while walking. The system is actually quite comfortable for smokers who follow it — Japan provides more designated smoking spaces than most European cities. Follow the signs, and you will have no trouble.
