Construction Wages in Japan: Look Up Your Own Trade

Chapter 01

Japan Publishes a Price for Your Trade

The document is called the 公共工事設計労務単価 (kōkyō kōji sekkei rōmu tanka) — the design labour unit price for public works. It’s published by the Ministry of Land, Infrastructure, Transport and Tourism.

What it covers

It sets a daily rate for 51 trades, in each of the 47 prefectures. Not a national figure with regional guesswork attached — an actual number for, say, a steel fixer in one prefecture and a different number for the same trade in another.

When it changes

Every year, in March. The current edition was announced on February 17, 2026 and applies from March 2026.

The figures come from the public works labour cost survey carried out the previous fiscal year. So the rate isn’t set by negotiation or by decree — it’s a measurement of what was actually being paid, fed back into what the state will price work at next.

Why it exists at all

This is the part that explains everything else about it.

The rate exists so that public construction work can be priced. When a government body puts a project out to tender, somebody has to calculate what the labour in that project costs. The unit price is the number used for that calculation.

That purpose is worth holding onto, because it’s the reason the number behaves the way it does — and the reason it is not, and was never meant to be, a wage.

Chapter 02

What Each Trade Is Worth

Here are the twelve main trades at the national average, under the rates applied from March 2026. The percentage is the change from the previous year.

The weighted average across all 51 trades is ¥25,834, which is the first time the figure has gone above ¥25,000. The twelve main trades above average ¥24,095.

What the spread tells you

Look at the top and the bottom. A formwork carpenter is valued at nearly twice a grade B traffic control guard — ¥31,671 against ¥16,749.

That gap is the clearest statement in the whole document about what Japanese construction considers skilled work. The trades that shape the structure sit at the top. They’re also, not coincidentally, the trades where it takes years to become useful.

A note on currency

I’m giving these in yen only, deliberately. Exchange rates move, and a conversion I write today is wrong by the time you read it. Convert at whatever today’s rate is — and remember you’d also be spending in yen, so the conversion matters less than it looks.

Chapter 04

The Sentence the Ministry Had to Write

Now the most important part of the document, and it isn’t a number.

On the first page of the announcement, in the summary of key points, the ministry writes this:

The design labour unit price for public works does not include the personnel costs that the employer is required to bear. Accordingly, failing to include those necessary costs in subcontract payments, or deducting them from subcontract payments, is an improper act.

Read it twice. There are two separate statements in there and both matter.

One: the rate is not a wage

The published figure excludes the costs the employer has to carry — the employer’s share of social insurance and the rest of what it costs to employ somebody rather than simply to have them show up.

So the daily rate is not what lands in a worker’s hand, and it was never supposed to be. It’s a component used to price work, not a wage being announced.

Two: and don’t treat it as a ceiling

The second half of the sentence is doing something different. It’s telling the people who read this document what they must not do with it: do not leave those costs out of what you pay down the chain, and do not deduct them. That, the ministry says, is improper.

What I’m not going to do here

I’m not going to speculate about why a ministry needed to write that sentence, or about how often the thing it warns against happens.

What I’ll say is only this, because it’s visible on the page: the warning is there, it’s in the summary of key points rather than buried in an appendix, and somebody decided it needed to be said.

Sources: Ministry of Land, Infrastructure, Transport and Tourism, on the design labour unit price for public works applied from March 2026, announced February 17, 2026, and the accompanying announcement document. The quotation above is my translation of the third key point on its first page.

Chapter 07

What Moves Your Number

Two things sit on top of the daily rate, and they pull in opposite directions.

Allowances: there is no standard

You’ll hear about allowances. Overtime, weekend work, hazardous work, sites that are a long way from home — these come up constantly in conversations about pay.

I can’t give you a table of them, and I want to be clear about why: allowances are set by each company. There isn’t an industry standard, there isn’t a published schedule, and two employers doing identical work can handle them completely differently.

That makes them something to ask about, not something to look up. And it makes them a reasonable test of an employer: a company that can answer precisely what allowances exist and under what conditions is telling you something about how it runs.

Gross is rising. Take-home is not keeping up.

Here’s the part I’d want to be told, if I were arriving.

Pay in Japan has been going up. You’ve seen it twice already in this article — the official daily rate has risen fourteen years running, and the national wage figure is at a record.

But the amount deducted before the money reaches you has been going up as well.

My own observation, from watching pay slips over years rather than from a statistic: the face amount increases, and what actually lands doesn’t increase with it. I can’t put a figure on that gap and I’m not going to pretend to. It’s what I see.

So if you read “wages in Japan are rising” and picture your bank balance rising at the same rate — adjust that picture.

Three years

Which leads to the practical conclusion I’d give someone planning to come.

If you want to get past that — to reach the point where the increases are actually showing up in what you take home — my honest estimate is that you need to stay around three years.

That’s a judgement, not a rule, and nobody will show you a document that says it. But it’s the number I’d give a person asking me whether this is worth doing, and it has a consequence worth thinking about before you start: the first year or two are not where the money is. They’re where the skill is. The money comes after, and only if you’re still there.

Chapter 08

The Supervisor Is Paid Differently

One structural difference is worth knowing, especially if you’re deciding which part of this industry to aim at.

Days off

The trades are on nikkyū geppō — paid for the days they work.

Site supervisors are not. A supervisor is on a monthly salary, and a day off doesn’t reduce it. Rain, a public holiday, a day the site is closed — the salary is the same.

That is a genuinely different relationship with the calendar. For a trade, a lost day is lost money. For a supervisor, it isn’t.

I’d add one honest qualification before anyone concludes the supervisor’s deal is simply better. The security sits on one side of the ledger; the hours sit on the other, and I’ve written elsewhere about what this industry’s hours used to be and what the 2024 overtime cap changed. Read that before you decide which one you want.

What to ask before you agree to anything

Here’s the whole article turned into questions. Ask these, in this order, and write the answers down.

1. **Is this nikkyū geppō, or a monthly salary?** You now know the difference and why it matters.
2. What happens on a rained-off day? Is there a guarantee, do you get sent to another site, or is it unpaid?
3. Which allowances exist, and what are the conditions for each? There’s no standard, so a vague answer is itself an answer.
4. **What is the daily rate, and how does it sit against the published rate for this trade in this prefecture?** Not a demand — a comparison you’re entitled to understand.
5. If you’re coming through the specified skilled worker route, ask how the employer demonstrates pay equal to a Japanese worker with equivalent skills. It’s a requirement, so there should be an answer ready.

And one thing to do before the conversation

Look your trade up.

The rates are published per trade and per prefecture, every March, by the ministry. Find the number for the work you’d be doing, in the place you’d be doing it, and go into the conversation knowing it.

You will almost certainly be the only person in the room who did — and whatever the answer turns out to be, you’ll be having a different conversation than you would have had otherwise.
