Smokers and Non-Smokers at Work in Japan (2026): Small Courtesies That Prevent Friction
Table of contents
The legal frame, briefly
Offices, factories and shops are Type-2 facilities: non-smoking indoors unless a compliant smoking room has been set up. Type-1 facilities such as schools, hospitals and government offices are smoke-free on the whole premises, which matters when you visit a client. Under-20s cannot enter smoking areas at all. See the Health Promotion Act explainer and the smoking etiquette basics for the full picture.
Courtesies that come up most often
- Leave a gap before close-range conversations, client visits and customer-facing work — assume nothing about how the other person feels about it
- Be extra mindful in small, poorly ventilated meeting rooms where several people spend a long time
- Keep ashtrays and smoking gear out of shared break rooms and locker areas
- If something bothers you, propose an action ("let's open a window in this room") rather than commenting on the person
- Say thank you when a colleague adjusts — acknowledged courtesy tends to continue
Do not let the smoking room become the meeting room
The most persistent complaint in Japanese offices is not smell — it is that conversations in the smoking room turn into decisions. This affects non-smokers, remote workers, part-time staff and anyone on another floor equally. A simple team rule fixes it: whatever is decided has to be written up in chat or in the meeting notes before it counts. It also helps people who were on leave that day.
When rank is involved
Raising this upwards is hard, and managers often do not notice. Setting the expectation as a team rule, before anyone has to complain, avoids leaving one person to absorb the discomfort. Inviting a direct report to the smoking room for a one-to-one is an invitation that is awkward to decline; holding one-to-ones in a meeting room or online removes the problem entirely.
Stepping outside
If your building has no smoking room, you will be using a designated outdoor spot. Some municipalities restrict street smoking, and the rules differ by area, so check your local government's official information. You can find the nearest designated spot on the MottoSuitai map. Smoking near a building entrance or beside neighbouring homes and shops is a common source of complaints — use the designated area.

Frequently Asked Questions
Q.Can I smoke inside a Japanese office?
A.Only inside a compliant smoking room. Since April 2020 offices are non-smoking indoors by default; a sealed smoking room permits cigarettes but no food or drink, and a heated-tobacco-only room permits heated tobacco devices with food and drink. Anyone under 20 is barred from smoking areas.
Q.Should I avoid smoking before a client meeting?
A.It is the safer default. You cannot know how the other person feels about it, and some client sites — hospitals, schools, government offices — are smoke-free across the entire premises. Checking the venue type beforehand saves awkwardness on the day.
Q.How do I raise the smell issue with a colleague?
A.Proposing a concrete action, such as opening a window or moving to a better-ventilated room, tends to work better than commenting on the person. If saying it each time is a burden, it can be set as a team rule through your manager or HR.
Q.Decisions keep getting made in the smoking room. What can I do?
A.Ask for a team rule that decisions only count once written up in chat or meeting notes. Framed that way it is not about smoking — it also covers remote workers and anyone who was away that day.
