Asking Family to Smoke Elsewhere (2026): Visiting Parents, Going Home, and Bringing the Grandchildren

Why the family home is a different conversation

With a partner you share a home and can adjust gradually; with parents or in-laws you are asking about a space that is theirs, on a visit that may last three days and recur twice a year. That asymmetry is the whole problem. A request that would sound routine between people who live together — "not in this room while the baby sleeps" — can land as a judgement on decades of how the household has run. It also concentrates everything into a narrow window, which is why so many of these conversations happen in the entryway with luggage still in hand, in the worst possible tone. Three adjustments defuse most of it: limit the scope to this visit rather than to the household in general, raise it in advance rather than on arrival, and decide who in your own household will do the talking before you get there. On that last point, when in-laws are involved, it is generally easier coming from the person who grew up in that house — but the important part is agreeing it in advance, so a family question does not turn into a couple's argument on the day.

The part most people skip: answering "then where?"

A request to not smoke in a particular room only holds if there is a realistic alternative, and "realistic" has to include the rainy evening and the cold night. So the productive move is to decide the alternative together rather than leaving it as the other person's problem: the veranda, the garden, the entrance, the parking space — whichever does not sit on the route children take through the house. In an apartment building, balcony use may be governed by the building's management rules, so that is worth checking separately, along with where neighbours' windows, laundry and air-conditioning units sit. For outings during the visit, checking in advance whether there is a designated smoking area near where you are going removes the awkward interval where someone wanders off to look for one. There is a quiet social effect here too: sitting down together and looking at a map turns the conversation from a confrontation into a shared task, which is a better position to negotiate from than facing each other across a table.

You can look up designated smoking areas near where you are heading on the MottoSuitai smoking area map. For basic outdoor consideration, see the basics of smoking etiquette; for conversations with a partner rather than parents, our guide to discussing smoking with a partner covers that separately, and eating out with children is covered in our guide to dining out with children.

When grandchildren are involved

Bringing children makes the request easier to justify and easier to get wrong. What damages the relationship is the conditional form — "we cannot bring them unless you agree to this" — even when that is genuinely how the parents feel. A published rule is a gentler footing. Tokyo's ordinance to protect children from second-hand smoke, in force since 1 April 2018, states in Article 6 that a person intending to smoke shall endeavour not to smoke in the same room as a child at home, and in Article 8 that they shall endeavour not to smoke in a car carrying a child. Every provision is a duty of effort and the ordinance carries no penalties (source: Tokyo Metropolitan ordinance text, https://www.reiki.metro.tokyo.lg.jp/reiki/reiki_honbun/g101RG00004895.html). Quoting that turns "the line I am drawing" into "the line that already exists", which is much easier to accept. Whether a comparable ordinance exists where your family lives is worth checking on the local government's own pages, since provisions differ by prefecture and municipality.

For the person being asked

• Resist the maximal reading. "Not in this room while the baby is awake" is not "stop smoking"; asking "which situation bothered you most?" narrows it usefully
• Offer the alternative yourself — "I will step out to the garden while they are up" — which moves you from being asked to co-deciding
• Article 27(1) of the Health Promotion Act asks people who smoke to have regard to the surroundings, including outdoors and on private land (source: https://www.city.arakawa.tokyo.jp/a033/kenkouiryou/kenkouzukuri/haryogimu.html). Raising it yourself reframes the whole exchange
• Check the building rules if a balcony is involved, and where neighbours' windows and laundry are if the garden is
• Remember that no one under 20 may enter a smoking area at all, even without smoking (source: MHLW, https://jyudokitsuen.mhlw.go.jp/point/) — worth factoring into outings with grandchildren
• Write the agreement down briefly, so the next visit does not start from scratch

Scope of this article

This is a third-party guide to family communication, based on Japanese public sources as of August 2026. It does not recommend that anyone quit smoking, nor does it encourage smoking; if quitting is under consideration, that is a conversation for a medical professional. Statements about health effects are quotations from public bodies rather than judgements of our own. Ordinances differ by prefecture and municipality and are amended over time, so confirm the position where your family lives with the relevant local government. Smoking under the age of 20 is prohibited in Japan.
