Fire Safety in Japan: Smoke Alarms, Extinguishers and 119

Japanese homes must have residential fire alarms, jūkeiki (住警器), which often sound a tone and a voice saying kaji desu, kaji desu, there's a fire. If there is a real fire, warn others, call 119 and say kaji desu, then give your address. A short chirp or a voice saying the battery is empty means the alarm needs a new battery or replacing.

What you need to know

Fire safety in Japan has its own sounds and words: the voice of the alarm in your ceiling, the bell in your building, the instructions on the balcony partition, the questions the 119 operator asks. Knowing them in advance turns panic into a few clear steps. This guide explains residential fire alarms and what their sounds mean, what to do when cooking smoke sets one off, how to use a fire extinguisher, what building fire drills involve, the signs in apartment buildings, and exactly how a 119 fire call goes. Rules on where alarms are required are set by each municipality, and alarm messages differ by model, so check your own device and your local fire department's page. In a real emergency, follow the instructions of firefighters and building staff.

Never block the balcony partition or the escape hatch

Fire safety in four lines

Kaji (火事) is the everyday word for a fire in a building. These four lines are what you hear from an alarm, what you shout to others and the two things you look for.

Residential fire alarms and what they say

The Fire Service Act requires residential fire alarms, jūtakuyō kasai keihōki, often shortened to jūkeiki, in Japanese homes. Where exactly they must go is set by each municipality: bedrooms are standard, stairways are required in many layouts, and some areas also require them in kitchens. Most alarms detect smoke; kitchens often have heat detectors instead.

Many models speak. A real alarm typically sounds a tone and then kaji desu, kaji desu. A short beep at intervals or a voice saying the battery is empty means the battery is low or the unit has a fault. Fire departments generally recommend replacing alarms about ten years after installation; the date is often printed on the unit.

False alarms from cooking or steam

Grilling fish, burnt toast or steam from the bathroom can set off an alarm. If you are sure there is no fire, press the stop button or pull the cord on the alarm, open a window and turn on the extractor fan. Many alarms reset themselves when the smoke clears.

In an apartment building, a home alarm may be connected to the building's system or a security company, and staff may come to check. If a neighbour or staff member knocks, explain calmly.

JapaneseRomajiMeaning
料理の煙で鳴ってしまいました。Ryōri no kemuri de natte shimaimashita.It went off because of cooking smoke.
火事ではありません。大丈夫です。Kaji de wa arimasen. Daijōbu desu.There's no fire. Everything's fine.
お騒がせしてすみません。Osawagase shite sumimasen.Sorry for the disturbance.

Using a fire extinguisher

A small fire that has just started, such as a pan or a wastebasket, may be put out with an extinguisher. If flames reach the ceiling, or you are not sure, leave, close the door behind you and call 119. Many apartment buildings have extinguishers in the corridors; find yours before you need it.

JapaneseRomajiMeaning
安全ピンを抜くanzen pin o nukupull out the safety pin
火元に向けるhimoto ni mukeruaim at the source of the fire
油に水をかけないで。Abura ni mizu o kakenaide.Don't pour water on the oil.
  • Pull out the safety pin, anzen pin (安全ピン), at the top.
  • Take the hose and aim at the base of the fire, not the flames or smoke.
  • Squeeze the lever firmly and sweep from side to side.
  • Keep your escape route behind you; back away if the fire grows.

Never pour water on burning cooking oil: it can make the fire explode outwards. Turn off the heat if you safely can and use an extinguisher, or cover the pan if you know how, then call 119.

Calling 119 for a fire

119 is for fire and ambulance. The operator asks questions in a fixed order, so you only need to answer one at a time. Speak slowly; the operator will ask again if needed.

A 119 call: the operator asks whether it is a fire or an ambulance, the caller says it is a fire and gives the address, then says the kitchen is burning.
Fire or ambulance, the address, what is burning: answer the operator one question at a time.
JapaneseRomajiMeaning
火事ですか、救急ですか。Kaji desu ka, kyūkyū desu ka.Operator: Fire or ambulance?
火事です。Kaji desu.You: It's a fire.
住所を教えてください。Jūsho o oshiete kudasai.Operator: Please tell me the address.
台所が燃えています。Daidokoro ga moete imasu.You: The kitchen is on fire.
逃げ遅れた人はいますか。Nigeokureta hito wa imasu ka.Operator: Is anyone trapped inside?
いいえ、みんな外に出ました。Iie, minna soto ni demashita.You: No, everyone is outside.

If you do not know the address, give a landmark: the building name, a nearby station, a convenience store or a school. Utility poles and vending machines in Japan often carry a small address sticker, which can help.

Preventing fires at home

Most home fires start with everyday things. Japanese fire departments regularly name a few common causes: cooking left unattended, heaters too close to washing or bedding, cigarettes, and electrical plugs. A few habits remove most of the risk.

JapaneseRomajiMeaning
コンロの火をつけたまま離れないkonro no hi o tsuketa mama hanarenaidon't leave the stove while it's on
ストーブの近くに物を置かないsutōbu no chikaku ni mono o okanaikeep things away from the heater
コンセントのほこりを掃除するkonsento no hokori o sōji suruclean the dust off the sockets
  • Stay in the kitchen while frying or grilling, and turn off the heat when you leave the stove, even for a moment.
  • Keep heaters away from curtains, futons and drying laundry, and switch them off before sleeping or going out.
  • Clean dust from behind plugs that stay in the socket for years, such as the fridge and TV; dust and moisture can cause tracking fires, called torakkingu genshō.
  • Do not overload power strips, and replace cords that are cracked or hot to the touch.
  • If you smoke, use a deep ashtray with water and never smoke in bed.

Fire drills and signs in apartment buildings

Larger apartment buildings hold fire drills, shōbō kunren (消防訓練) or hinan kunren (避難訓練), announced by a notice in the lobby. Joining once is the easiest way to learn where the stairs, extinguishers and exits are.

On many balconies, the thin partition between your balcony and the next is designed to be broken through in an emergency. It is marked with a sign meaning in an emergency, break through here to escape to the next unit. Some balconies also have an escape hatch with a ladder, hinan hacchi. Never block either with plants, storage or a washing machine.

JapaneseRomajiMeaning

避難ハッチhinan hacchiescape hatch on the balcony

Mistakes that make fires worse

  • Removing the alarm's battery because of cooking smoke. Use the stop button instead and ventilate.
  • Blocking the balcony partition or escape hatch with storage. Neighbours may need it as much as you.
  • Using the lift during a fire. Use the stairs.
  • Going back for belongings. Get out, close doors behind you and stay out.
  • Assuming someone else has called 119. If you see a fire, call.

Make the 119 call automatic

Give Mocchi your address and ask for a 119 fire call script with the operator's questions and your answers. Come back later and ask to be quizzed on the call line by line until you no longer need to read it.

Then listen to how it sounds at speed: use /pronounce in the chat to practise saying your address and kaji desu clearly, because a calm, clear address is the most useful thing you can give the operator.

Key points

A practical way to improve

Rehearse the 119 call until it comes out without thinking. First, write your full address in Japanese and read it aloud, including the building name and room number. Second, say the four answers in order: kaji desu, the address, what is burning and whether anyone is trapped, then your name and phone number. Third, practise telling a neighbour to get out: kaji desu, nigete kudasai. Mocchi, Unihongo's study assistant, can check your address and lines and quiz you on the alarm and sign words.

FAQ

Frequently asked questions

What does a Japanese smoke alarm say?

Many voice models sound a tone followed by kaji desu, kaji desu, there's a fire. Some interconnected alarms say which room detected smoke. Messages differ by manufacturer and model, so check the manual or the label on your alarm.

Why is my fire alarm beeping once in a while?

A short beep at intervals, or a voice saying the battery is empty, usually means the battery is low or the device has a fault. Many residential alarms are sealed units, and fire departments generally recommend replacing the whole alarm about ten years after installation. In a rental, tell the management company.

Are smoke alarms required in Japanese homes?

Yes. The Fire Service Act requires residential fire alarms in homes, and each municipality's ordinance sets where: commonly in bedrooms and, depending on the layout, stairways, and in some areas kitchens too. Many apartment buildings have their own building-wide systems as well. Check your city's fire department page.

What do I say when I call 119 for a fire?

The operator first asks kaji desu ka, kyūkyū desu ka: is it a fire or an ambulance? Answer kaji desu. Then give the address, what is burning, whether anyone is trapped or injured, and your name and phone number. Stay on the line if it is safe and follow the instructions.
