Smoking Areas at Kichijoji Station: 2026 Guide (Musashino City no-street-smoking districts and the smoking trailer houses)

About this guide and disclaimer

This is a third-party guide reflecting the situation as of July 2026, compiled from Musashino City's official site (https://www.city.musashino.lg.jp/): its guidance on no-street-smoking districts, its guidance on the city's smoking areas (smoking trailer houses), and its FAQ on whether there is a fine for street smoking. Smoking area locations, hours and district boundaries may change without notice. This article does not encourage smoking. Smoking by people under 20 is prohibited by law in Japan. When you actually go, always confirm the latest information on Musashino City and each facility's official guidance.

Musashino City's no-street-smoking districts (no fine system; based on guidelines)

To address the dangers of smoking while walking in busy places such as the shopping districts around stations, health concerns about second-hand smoke, and littering of butts, Musashino City designates areas around its stations as "no-street-smoking districts." The basis is not an ordinance but the "Musashino City Welcome Beautiful Town Promotion Programme Guidelines." As of July 2026, the districts the city lists are as follows.

• Around Kichijoji Station (designated April 2004)
• Around Mitaka Station North Exit (designated July 2005)
• Around Musashi-Sakai Station (designated July 2005)
• Kichijoji East district (added April 2025)

On penalties, Musashino City's official FAQ states: "There is no fine system. We ask for your cooperation in following the rules and good manners when smoking, so that both smokers and non-smokers can spend their time comfortably in our town." The city explains that it considered the fine systems used by other municipalities but decided against introducing one, citing practical problems such as the lack of enforcement power for collection and the cost of patrols. So there is no mechanism to collect a fine for street smoking in Kichijoji — but it is still a no-street-smoking district, and the premise is that you refrain from smoking on the street.

The exact boundaries of the districts (which streets are covered) are meant to be checked on the no-street-smoking area maps (PDF) published by Musashino City. This article does not assert the boundaries, so please check the detailed extent on the city's official maps.

City-operated smoking areas around Kichijoji Station (smoking trailer houses)

Musashino City has installed enclosed smoking areas near stations in the city. These are called "smoking trailer houses"; according to the city, they can be installed outdoors and, being towable, can be relocated. The city also explains that a plasma deodoriser purifies the smoke inside before it is exhausted, greatly reducing odour. There are two around Kichijoji Station.

• Kichijoji Station smoking area (Kichijoji-Minamicho 1-2, Musashino City) / daily 7:00–1:00 the next morning
• Kichijoji East smoking area (Kichijoji-Honcho 1-23, Musashino City) / daily 7:00–1:00 the next morning

Around Kichijoji Station, foot traffic differs greatly between the south side (Park Exit, towards Inokashira Park) and the north side (Sun Road, Harmonica Yokocho). The two smoking areas above are in different neighbourhoods, so which one to head for depends on which side of the station you are on. They are usable late — until 1:00 the next morning — but note that they are closed before 7:00. Locations and hours may change, so always check Musashino City's official site before you go.

Mitaka Station North Exit and Musashi-Sakai Station (note the different hours)

Mitaka Station and Musashi-Sakai Station, one and two stops from Kichijoji on the Chuo Line, also have Musashino City smoking areas. Their hours differ from the two in Kichijoji, so if you plan to stop by while changing trains, checking in advance is essential. There are four city smoking areas in total.

• Mitaka Station North Exit smoking area (inside DAICHI PARK No. 177 Mitaka Station North Exit car park, Nakacho 1-16, Musashino City) / Monday–Saturday 7:00–23:00 (closed Sundays, public holidays and 29 December–3 January)
• Musashi-Sakai Station smoking area (Kyonancho 2-1, Musashino City) / Monday–Saturday 7:00–23:00 (closed Sundays, public holidays and 29 December–3 January)

At Mitaka Station, the north exit is in Musashino City and the south exit is in Mitaka City, so the municipality responsible changes depending on which exit you use. The one listed as a Musashino City smoking area is on the north side. Being closed on Sundays, public holidays and over the New Year period is also a significant difference from the two in Kichijoji, which are open every day.

We do not assert whether you can smoke in Inokashira Park

Inokashira Park, right by the south side of Kichijoji Station, is a Tokyo Metropolitan park (spanning Musashino City and Mitaka City). At the time of research for this article, we could not find any statement on the Tokyo Metropolitan Government Bureau of Construction's official page for Inokashira Park indicating whether smoking is allowed in the park or whether smoking places exist. This article therefore does not assert whether you can smoke inside Inokashira Park or whether there are smoking places.

Park rules are set by the park manager, and on-site signage takes precedence. If you plan to visit Inokashira Park, check the latest rules on notices at the entrances and inside the park, on the Bureau of Construction's official page, or with the park office. The Ministry of Health, Labour and Welfare states that even where smoking is not prohibited, such as outdoors or at home, smokers have a duty to consider their surroundings so as not to cause unwanted passive smoking. During cherry blossom season and at weekends Inokashira Park is full of families and children, and the boat pond and open areas get especially crowded. Regardless of whether rules exist, avoid smoking near other people.

Points to note in shopping streets such as Sun Road and Harmonica Yokocho

Sun Road shopping street and Harmonica Yokocho on the north side of Kichijoji Station, and the Park Road area on the south side, have very high pedestrian volumes relative to their width. In arcades and narrow alleys, walking with a lit cigarette risks contact with people and children around you. Musashino City set up its no-street-smoking districts precisely to address the dangers of smoking while walking in such busy places.

• In no-street-smoking districts, refrain from smoking on the street and move to a city smoking area
• Do not litter butts (carry a portable ashtray)
• In arcades, alleys and near queues in front of shops, refrain from smoking even outside the districts
• In front of restaurants or facing homes, be mindful of which way the smoke drifts

As noted below, indoor areas of restaurants and cafés are in principle non-smoking under the revised Health Promotion Act. Whether smoking is possible can be checked from the signage at the entrance. Because individual shops change their policies easily, this article does not name specific shops or assert their smoking policy.

Indoors is in principle non-smoking (revised Health Promotion Act), and heated tobacco

Under the revised Health Promotion Act, fully in force since April 2020, indoor areas of facilities used by many people are in principle non-smoking. Restaurants and commercial facilities in Kichijoji are also in principle indoor non-smoking, and smoking is possible only inside a dedicated smoking room where one has been provided. Places where smoking is allowed must display signage, and people under 20 may not enter smoking areas, whether as customers or staff. If you want to smoke indoors, check for the signage and use a venue with a smoking room.

For heated tobacco, the revised Health Promotion Act provides categories that differ from cigarettes in some cases, such as "smoking-purpose rooms" where eating and drinking are possible, or smoking rooms dedicated to heated tobacco. However, Musashino City's no-street-smoking districts are an outdoor rule: even when using heated tobacco outdoors, refrain from smoking on the street and use a city smoking area. Treatment of e-cigarettes (including nicotine-free products) varies by product and facility, so follow the signage at each shop or facility.
