The big picture: Two layers of law
Smoking rules in Japan operate on two layers: (1) the national Health Promotion Act, which mainly governs indoor smoking at facilities used by the public; and (2) local by-laws set by individual cities and wards, which can prohibit street smoking in designated zones and impose on-the-spot fines. As a tourist, you need to be aware of both.
Layer 1 — National Health Promotion Act (indoor smoking)
The Act's 2020 revision divides facilities into categories: Category I (schools, hospitals, government buildings) must be entirely smoke-free, including outside the building if owned by the facility. Category II includes most restaurants, hotels, and offices — they must be non-smoking inside, with the option to operate a sealed indoor smoking room. Heated tobacco devices (IQOS, glo, Ploom) are regulated the same way as combustible cigarettes.
Small restaurants operating before April 2020 with limited floor area and registered as "existing small restaurants" have a transitional exemption and may allow smoking throughout the premises if they display the proper sign. Read the sign at the entrance — pictograms indicate whether smoking is allowed, prohibited, or restricted to a separate room.
Layer 2 — Local by-laws (outdoor / street smoking)
The national act imposes only an outdoor consideration duty without a fine, but many cities add their own by-laws. Examples confirmed as of May 2026:
• Kyoto City: "Street Smoking Prohibited Strengthened Zones" in central Kyoto, Kyoto Station area, Kiyomizu-Gion area. Fine: JPY 1,000 on the spot (source: Kyoto City https://www.city.kyoto.lg.jp/bunshi/page/0000291969.html). • Most of Tokyo's 23 wards (Chiyoda, Chuo, Minato, Shinjuku, Shibuya, etc.) have their own smoking-prohibited zones with fines of JPY 1,000–2,000. • Osaka City: Tightening on-the-spot fines around major stations. Always check the city or ward where you are walking.
Outdoor smoking: even where no fine, watch your behaviour
Even where no local by-law exists, walking-and-smoking ("aruki-tabako") and dropping cigarette butts ("poi-sute") are strongly socially disapproved of throughout Japan. Walking-and-smoking also poses a burn risk to children at face height. The cultural norm: walk to a designated smoking spot, smoke, dispose of the butt only in a portable ashtray or official ashtray.
Where you can smoke — practical options
Look for: (1) outdoor designated smoking spots run by the city or station operator (often near train station exits or in pocket parks); (2) outdoor smoking spaces at hotels and large commercial complexes; (3) sealed indoor smoking rooms inside large facilities; (4) outdoor terrace seating at restaurants that explicitly mark themselves as smoking-permitted; (5) heated tobacco lounges (for example, IQOS Smoking Areas) run by tobacco companies in some cities.
Heated tobacco (IQOS, glo, Ploom)
Heated tobacco devices are not exempt. They fall under the same Health Promotion Act rules as combustible cigarettes for indoor smoking, and the same outdoor consideration duty applies. Some restaurants and venues do operate heated-tobacco-only smoking rooms — confirm at the entrance.

Quick checklist before you light up

Frequently Asked Questions
Q.Can I smoke on the street anywhere in Japan?
A.No. The national Health Promotion Act imposes a legal duty to avoid causing unwanted second-hand smoke. On top of that, many cities (Kyoto, Osaka, most Tokyo wards) impose on-the-spot fines of JPY 1,000–2,000 in designated "Street Smoking Prohibited Zones". Always check the local by-law and use designated smoking spots.
Q.Are restaurants in Japan smoke-free?
A.Most restaurants are non-smoking indoors. Larger restaurants may operate a sealed indoor smoking room. "Existing small restaurants" registered before April 2020 may be exempt — read the entrance sign. Outdoor terraces are typically outside the indoor ban and may allow smoking at the operator's discretion.
Q.Is IQOS / glo / Ploom legal in Japan?
A.Yes, heated tobacco devices are legal in Japan and widely sold. They are regulated the same as combustible cigarettes under the Health Promotion Act, so you cannot use them indoors except in designated smoking rooms. Some restaurants operate heated-tobacco-only smoking rooms.
