Smoking in Japan: where you can and cannot smoke

Indoors, smoking is banned as a general rule. You can smoke only in designated smoking rooms, and outdoor rules depend on the city. Check the sign at the entrance.

The basic rule

Since 2020, a revised national law (the Health Promotion Act) makes indoor spaces smoke-free as a general rule. Heated tobacco is also covered in many places.

Smoking is allowed only in places that the law permits, such as a designated smoking room.

Different places, different rules

Look for the signs

A place with a smoking room must show a sign at the main entrance and at the smoking room door. In Tokyo, restaurants must also show their smoking status at the shop front. Look at the sign before you sit down.

Outdoors

Outdoor smoking rules are set by each city or ward, and many have designated smoking areas. If you cannot find a sign, look for an ashtray area or ask a local shop.

Even where smoking is allowed, think about the people around you.

Age limit

People under 20 cannot enter smoking rooms. Tokyo's ordinance specially protects under-20s and employees from second-hand smoke.
