Japanese for Car Mechanics: Workshop Safety and Customer Phrases

In a Japanese workshop the first words you need are not the names of parts. They are the calls you make before a lift moves or an engine starts.

Japanese for Car Mechanics: Workshop Safety and Customer Phrases

Car maintenance in Japan runs on a narrow, repetitive set of Japanese: safety calls around lifts and engines, a vocabulary of parts that is mostly katakana, instructions that arrive while someone is pointing at a wheel, and short reports about what you found. Many workshops also expect you to greet customers and hand them to the right person. This guide covers the safety language first, then parts and tools, confirming instructions, reporting faults and the counter. It is written for mechanics who already know the work and need the Japanese around it.

Say the safety call before moving a lift or starting an engine, every time

Most parts are katakana words said with Japanese vowels

Repeat instructions back, especially sides, numbers and torque

Report worn parts, leaks and lost bolts straight away

Safety calls around lifts and engines

Workshop accidents happen when something moves and someone did not expect it. Japanese workshops handle this with short calls said before the action, loud enough for everyone nearby to hear.

Say the call even when you think nobody is close. A colleague under the next car may be out of your sight, and the call costs you a second.

JapaneseRomajiMeaning
リフトを上げます。Rifuto o agemasu.Raising the lift.
リフトを下げます。離れてください。Rifuto o sagemasu. Hanarete kudasai.Lowering the lift. Stand clear.
エンジンをかけます。Enjin o kakemasu.Starting the engine.
エンジンを切ってください。Enjin o kitte kudasai.Please turn off the engine.
輪止めをしました。Wadome o shimashita.The wheel chocks are in.
危ない!止めて!Abunai! Tomete!Look out! Stop it!
火気厳禁kaki genkinNo open flames (a sign you will see)

Parts and tools you will be asked for

Most parts have katakana names borrowed from English, which helps, but they are said with Japanese vowels and rhythm. Burēki paddo sounds very different from brake pads, and a colleague listening for the Japanese version may not catch the English one.

The Japanese words that are not katakana are the ones about the work itself: inspection, replacement, estimate. They come up in every conversation, so learn them early.

ブレーキパッドburēki paddoBrake pads
取り外す・取り付けるtorihazusu, toritsukeruTo remove, to fit

Confirming instructions: sides, numbers and torque

Instructions often come while your senior is pointing, and the details that go wrong are the side of the car, the number of parts and how tight something should be. Repeat those back as a short question. In Japanese workplaces this is normal practice, not a sign that your Japanese is weak.

Left and right are easy to confuse on a car. Many workshops say driver's side and passenger's side instead, and in Japan the driver's side is usually the right.

JapaneseRomajiMeaning
このボルトはどのくらい締めますか。Kono boruto wa dono kurai shimemasu ka.How tight should this bolt be?
規定トルクで締めました。Kitei toruku de shimemashita.I tightened it to the specified torque.
前輪ですか、後輪ですか。Zenrin desu ka, kōrin desu ka.Front wheels or rear wheels?
運転席側untenseki-gawaDriver's side
助手席側joshuseki-gawaPassenger's side
四本とも交換ですね。Yonhon tomo kōkan desu ne.All four get replaced, right?
すみません、もう一度お願いします。Sumimasen, mō ichido onegai shimasu.Sorry, once more, please.
やって見せていただけますか。Yatte misete itadakemasu ka.Could you show me?

Reporting what you find

Japanese workplaces put a lot of weight on reporting early, a habit often called hōrensō. In a workshop that means telling your senior about a worn part, a leak or a problem with the job before you carry on, not after.

Lost bolts and dropped tools belong in the same category. Saying so at once is expected; finding out later is what causes trouble.

JapaneseRomajiMeaning
ブレーキパッドがかなり減っています。Burēki paddo ga kanari hette imasu.The brake pads are quite worn.
オイルが漏れています。Oiru ga morete imasu.Oil is leaking.
走行中に異音がするそうです。Sōkōchū ni ion ga suru sō desu.The customer says there is a strange noise while driving.
部品の在庫がありません。Buhin no zaiko ga arimasen.The part is not in stock.
ボルトを一本なくしてしまいました。Boruto o ippon nakushite shimaimashita.I have lost one bolt.
作業が終わりました。確認お願いします。Sagyō ga owarimashita. Kakunin onegai shimasu.The job is done. Please check it.

At the counter with customers

Even if you never explain a price, you may be the first person a customer meets. A greeting, a question about why they came, and a polite promise to look after the car cover most first contacts.

When the conversation moves to cost, repair decisions or complaints, fetch the person in charge. Knowing that moment is part of the job, and saying so politely is better than guessing.

JapaneseRomajiMeaning
いらっしゃいませ。本日はどうされましたか。Irasshaimase. Honjitsu wa dō saremashita ka.Welcome. What can we do for you today?
お車をお預かりします。O-kuruma o o-azukari shimasu.We will look after your car.
お見積もりをお出しします。O-mitsumori o o-dashi shimasu.We will give you an estimate.
作業は二時間ほどかかります。Sagyō wa nijikan hodo kakarimasu.The work will take about two hours.
担当の者を呼んでまいります。Tantō no mono o yonde mairimasu.I will fetch the person in charge.

The last line is the most useful one on the list. It is polite, it is honest, and it gets the customer to someone who can answer.

A first-month plan for the workshop

The Japanese you need grows with the jobs you are given, so learn it in the same order as the work rather than from a general textbook.

  • Week one: the lift, engine and stop calls, said aloud every day.
  • Week two: the katakana names of the parts you handle most, in Japanese pronunciation.
  • Week three: confirming sides, quantities and torque as short questions.
  • Week four: reporting worn parts, leaks and problems, and the counter greetings.
  • Every day: write down one word you did not understand and ask about it before you go home.

Unihongo's pronunciation lab helps with katakana part names like burēki: its long vowel focus drills and scores the vowel length and mora timing that make these words sound like Japanese rather than English.

Key points

A practical way to improve

Learn the lift and engine calls first and say them aloud until they come out without thinking. Then ask your AI Sensei in Unihongo's immersive 3D classroom to play your senior mechanic and give you instructions with sides and numbers in them, and read the corrections in the session report afterwards to see which confirmations came out unclear.

  1. 1

    Choose one clear goal

    Focus each session on a situation or skill you can actually use.

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

How much Japanese does a car mechanic in Japan need?

Enough to follow safety calls, understand instructions about parts, sides and quantities, and report what you find. The vocabulary is small and repetitive, but it has to be reliable because mistakes in a workshop are expensive or dangerous.

Are car parts called by Japanese or English names?

Mostly by katakana versions of English words, such as burēki paddo for brake pads and oiru kōkan for an oil change. They are pronounced with Japanese vowels, so practise saying them the Japanese way or colleagues may not recognise them.

What is shaken?

Shaken is the statutory vehicle inspection that cars in Japan must pass at regular intervals. A lot of workshop work is preparing cars for it, so you will hear the word constantly.

Do I need to talk to customers?

In many workshops you greet customers and take their car, even if a senior explains prices and repairs. A few fixed polite phrases, and knowing when to fetch the person in charge, cover most of it.
