The Song That Sells Kerosene
Stay in a rental flat instead of a hotel in winter and, some afternoon, a small truck will roll past playing a slow children's song through a loudspeaker. It is not an ice-cream van. It is selling heating oil, and the tune it plays depends on where you are.

By your third or fourth trip you may have swapped the hotel for a flat in a residential ward: Nerima, Nakano, Setagaya, a quiet part of Osaka. In November, around mid-morning or mid-afternoon, you hear it from a few streets away. A wobbly recording of a children's-songbook melody, getting louder, passing the window at walking pace, fading. It is selling tōyu (灯油), kerosene.
This is a sound, not a sight, so there is no station to get off at. What you get is the explanation for something you will otherwise hear every winter without knowing what it is, and a way to tell which part of Japan you are in by ear.
Why a truck sells heating oil door to door灯油 · tōyu
Many Japanese homes, especially older houses and flats, have no central heating. Rooms are heated one at a time, and the cheapest way to do it is often a portable kerosene fan heater. Kerosene is not piped in. Households buy it in red or blue plastic tanks, the standard size being 18 litres, and carry it home from a petrol station or have it brought to them.
An 18-litre tank weighs over a dozen kilograms full, which is exactly the problem the trucks solve. A small tanker with a pump and hose drives through residential streets in the cold months and fills customers' tanks at the door. Japanese write-ups on the trade give practical reasons for the music: the song carries further than an engine, it tells people to get their tanks out before the truck reaches them, and a familiar tune is less likely to be heard as noise than a voice shouting.
Where you'll hear it: Residential streets, not shopping districts or the centre of big cities. Detached houses and low-rise flats are its territory.
When: The cold months, roughly autumn to early spring. Sellers say demand is highest in midwinter.
Reality check: Routes and days are not published in any general way.
Which song, where灯油販売の曲 · tōyu hanbai no kyoku
There is no national kerosene song. Each seller picks one, and because sellers are local, the tune becomes local too. Japanese residents' reports, collected on a Japanese shopping-information site and in long question threads, line up roughly like this.
Song
What it is
Reported in
月の沙漠 Tsuki no Sabaku "Desert under the Moon"
A 1923 children's song, slow, in a minor key: two riders on camels at night
Tokyo: Nerima, Nakano, Setagaya, Adachi, the Tama area; also Kanagawa and Miyagi
雪 Yuki "Snow"
A school song known by its opening "yuki ya konko", published for primary schools in 1911
Osaka (used by the Kansai seller Shuwa), Nagoya, Hiroshima, Chiba; Sendai and Nishinomiya in other reports
たき火 Takibi "Bonfire"
A 1941 children's song about raking leaves into a fire in the cold
Hiroshima (used by Tamura Sekiyu), Kawasaki, Osaka, Aichi
めだかの兄妹 Medaka no Kyōdai
A 1982 pop song for children
Saitama (used by a seller based in Okegawa)
Company jingles
Original songs written for a brand
Parts of western Tokyo and Yokosuka (a Shell-brand "clean kerosene" song)
Outside Tokyo you mostly hear snow and fire; in Tokyo's suburbs, a slow camel ride across a desert.
Why a desert song for heating oil? Nobody has a documented answer. A Nerima resident who went looking for one ended up guessing that its lonely, cold sound makes you want to be warm, or that a company president simply liked it. The choices in the rest of the table explain themselves: snow, and a fire.
If you know the song, you know roughly where you are. If two different songs pass your window, two companies are working the same streets.
The rule that sets the timetable拡声機の規制 · kakuseiki no kisei
In Tokyo the truck's loudspeaker counts as commercial advertising under the metropolitan environmental ordinance, and the limits are what shape the sound you hear. Commercial loudspeakers may not be used between 19:00 and 08:00. Used in one place, they may run for ten minutes at most, followed by at least fifteen minutes of silence. They may not be used within 30 metres of a school or hospital, and the volume is capped, measured ten metres from the speaker. Other prefectures have their own versions.
So the truck keeps moving, plays during the working day, and goes quiet near schools. A Japanese article on the trade adds that complaints about volume and timing have grown, which is one reason the tunes chosen are soft rather than jingly.
Eleven hours a day, never parked for long: the rules are why the song always seems to be passing rather than arriving.
What it costs配達価格 · haitatsu kakaku
Delivery costs more than filling your own tank at a petrol station, and Tokyo is one of the dearest places to have it brought. In the national survey of 28 September 2026, as summarised from the Agency for Natural Resources and Energy's weekly figures, 18 litres averaged ¥2,538 at the pump and ¥2,721 delivered. Delivered in Tokyo, it was ¥3,039, the second highest in the country. Those prices already include a government subsidy of ¥50.7 per litre, about ¥913 per tank, in force from 1 October 2026.
Delivery adds about ¥180 a tank on the national average, and Tokyo pays close to the most in Japan to have it brought.
If your rental has a kerosene heater石油ファンヒーター · sekiyu fan hītā
Some older rentals and many rural houses come with a kerosene heater and a tank. If the tank is empty, the truck is one option; many sellers also take orders by phone or online, and a Kansai seller, Shuwa, lists phone and LINE ordering alongside its trucks. The other option is the petrol station, where you fill the tank yourself or ask the attendant.
Use kerosene only, never petrol, and open a window regularly while the heater is on: indoor kerosene heaters need ventilation to avoid carbon monoxide. If you hand the tank to a seller and they ask how much:
満タンでお願いします (mantan de onegai shimasu). Fill it up.
Where: At your door if a truck is passing; otherwise any petrol station with a kerosene pump.
When: Trucks in the daytime only, and only in the heating season.
Reality check: You cannot call a passing truck back, and you cannot rely on one coming. If the flat is cold tonight, go to the station.
The honest part
You cannot plan to hear this. There is no route map, no schedule and no guarantee a truck works the street you are staying on. Around the big hotel districts you are less likely to hear one; the trucks work residential streets.
The song map above is assembled from people's reports, not from any list published by the industry. Sellers change songs, and two neighbours can hear two different ones. Treat the table as a guide to listen with, not a fact sheet.
Most visitors will never need to buy kerosene. If you are only here for the sound, that is fine, and it is also all you will get: the truck goes by in a minute.
If you only have one day
A listening walk, for a weekday between November and March, in a residential part of western Tokyo. Nothing here is guaranteed; it is built around the hours the rules allow.
Seibu Ikebukuro Line to a stop in Nerima, away from the big stations, and walk into the streets of detached houses.
Walk slowly with no music in your ears. You are listening for a melody, slower than any jingle, getting louder from a few streets away.
Lunch near the station.
Walk a different direction for the afternoon round. If you hear it, note the song, the street and the time.
The light goes early in winter. Trucks have until 19:00 by law, but this is a good time to stop.
Running short of time? Skip the walk and ask whoever runs your guesthouse which song comes down their street. Locals usually know.
