How to Read Your Japanese Payslip as a Foreigner

Your offer letter said ¥400,000 a month. Your bank account got something much smaller. That feels bad the first time.

The good news is that this usually does not mean your company is cheating you. The bad news is that a Japanese payslip, or 給与明細 (kyuyo meisai), can still be hard to read, especially when the key deductions are listed in Kanji and the biggest surprise, 住民税 (juminzei), may not even show up until your second year.

If you just started working in Japan, this is the part that matters most: a payslip is not just a receipt. It is the monthly summary of how your employer, the tax system, and the social insurance system are treating your income.

Let’s decode it properly.

The First Thing to Know: Gross Pay Is Not Take-Home Pay

Japanese compensation is often quoted in a way that makes the gap between gross salary and take-home pay feel larger than expected.

What usually happens is:

• your contract or offer shows a base monthly salary
• your payslip adds any allowances and overtime
• then it subtracts social insurance and withholding tax
• the amount that actually lands in your bank account is the net amount

On many payslips, the amount you really care about is labeled one of these:

• 差引支給額 (sashihiki shikyu gaku) — net amount paid
• 控除後支給額 (kojo go shikyu gaku) — amount paid after deductions
• 手取り (tedori) — take-home pay, sometimes used informally rather than as the actual printed label

So if the deposit feels low, start here: compare your gross line and your net line before assuming something is wrong.

How a Japanese Payslip Is Usually Structured

Most Japanese payslips are built around three blocks:

1. Attendance / work record (勤怠)
2. Earnings (支給)
3. Deductions (控除)

The exact layout changes by company, but the logic is usually the same.

1. Attendance (勤怠)

This section shows the time record that feeds the payroll calculation.

Typical items include:

• 出勤日数 — days worked
• 有給日数 — paid leave used
• 欠勤日数 — unpaid absence days
• 残業時間 — overtime hours
• 深夜時間 — late-night hours
• 遅刻 / 早退 — late arrival / early departure

If your company pays overtime, this section is what should connect to the overtime payment line in the earnings block.

2. Earnings (支給)

This is the money added before deductions.

Common line items:

Japanese term	What it usually means
基本給	Base salary
役職手当 or 役付手当	Position or managerial allowance
残業手当	Overtime pay
通勤手当	Commuting allowance
住宅手当	Housing allowance
家族手当	Family allowance
皆勤手当	Perfect attendance allowance
賞与	Bonus

This is one place where foreign workers often miss something important: Japanese salary is not always one clean number. A company may split your compensation across base pay and allowances. That does not automatically make it bad, but it does affect how you should compare offers.

If you are deciding between two jobs, a bigger 基本給 is usually more durable than a package that depends heavily on special allowances or implied overtime.

The Deductions Section Is Where the Shock Usually Happens

The deduction block (控除) is the part that makes your first payslip feel smaller than your offer.

The main lines you will usually see are:

Japanese term	What it usually means
健康保険	Health insurance
介護保険	Nursing care insurance, usually only from age 40
厚生年金	Employees’ pension
雇用保険	Employment insurance
所得税	Withheld national income tax
住民税	Resident tax, often blank in the first year

Let’s break those down.

One thing you usually will not see as an employee deduction is 労災保険 (rosai hoken), or workers’ accident compensation insurance. In the normal setup, that premium is borne by the employer rather than deducted from your wages. JETRO’s social-security overview reflects that split.

Health Insurance and Pension Are Not Calculated on a Perfectly Raw Number

Japan’s employee health insurance and employees’ pension do not just take your exact salary for the month and multiply it directly.

Instead, the system uses 標準報酬月額 (hyojun hoshu getsugaku) and 標準賞与額 (hyojun shoyo gaku). In practice, your monthly wages are placed into brackets, and the premium is calculated from that bracket rather than from every yen literally earned that month. The Japan Health Insurance Association explains that this system also uses a separate standard bonus amount, rounded down to the nearest ¥1,000, for bonus calculations. It also notes that items like base salary, position allowance, family allowance, commuting allowance, housing allowance, and overtime pay are part of the remuneration base used for these insurance calculations.

That matters for two reasons:

• your deductions are tied to more than just 基本給
• allowances you may think of as “extra” can still increase the insurance base

JETRO’s overview of Japan’s social security system is also useful here: employers generally deduct the employee share from wages and pay it together with the employer share, and the health and pension systems are part of that normal payroll flow.

Employment Insurance Is Real, but Smaller

雇用保険 (koyo hoken) is unemployment insurance. It is usually a smaller deduction than health insurance or pension, but it still shows up on the payslip. The Ministry of Health, Labour and Welfare publishes the rate tables every year, which is one reason the exact percentage can change over time.

Income Tax on Salary Is Withheld First and Fixed Later

For normal employees, national income tax is usually withheld from salary and bonus during the year. Then the employer runs 年末調整 (nenmatsu chosei) to reconcile what was withheld with what you should actually owe for the year.

The National Tax Agency explains this clearly: salary and bonus income tax is withheld during the year, and the final payment of the year is where over- or under-withholding is adjusted.

That means:

• one monthly 所得税 line is not your final annual answer
• December or January can look different because of 年末調整 (nenmatsu chosei)
• if you qualify for extra deductions, your refund often shows up through payroll rather than as a separate event

A Concrete Example: What a First Payslip Might Look Like

Let’s make this real.

Imagine a foreign engineer in Tokyo with this setup:

• under 40
• single
• no dependents
• first year in Japan, so no 住民税 (juminzei) deduction yet
• enrolled in ordinary employee social insurance through work

Their contract says:

• 基本給 — ¥400,000
• 通勤手当 — ¥15,000

That means the gross amount for the month is often around:

• 支給合計 (shikyu gokei) — ¥415,000

Now imagine a payslip that looks roughly like this:

Line item	Rough amount
健康保険	¥20,000 to ¥21,000
厚生年金	¥36,000 to ¥37,000
雇用保険	about ¥2,000
所得税	often around ¥8,000 to ¥10,000
住民税	¥0 in the first year
控除合計 (kojo gokei)	roughly ¥66,000 to ¥70,000

That leaves a rough:

• 差引支給額 (sashihiki shikyu gaku) — about ¥345,000 to ¥349,000

So if someone looked at the contract, saw ¥400,000+, then saw a bank deposit in the mid-¥340,000s, that would feel like a big drop. But for a first-year employee setup like this, it is usually within the range of normal.

Why 住民税 Might Be Zero at First and Then Suddenly Appear

This is the second big foreigner surprise.

住民税 (juminzei) is based on the previous calendar year’s income. So if you just arrived in Japan and had no Japanese income in the prior year, your first months here may show no resident tax deduction at all.

Then the trap arrives.

Shibuya City’s English tax guidance lays it out simply:

• if you were a resident there on January 1
• and you had income in the previous calendar year
• you are subject to resident tax
• company employees typically have it deducted from salary from June until May of the following year

So if your first year in Japan feels manageable and your second year suddenly feels tighter, this is often the reason.

This is the same problem Persona 2 runs into. Their salary did not suddenly get cut. Their payslip just started reflecting a tax that was not being deducted yet in year one.

Using the same example above, a second-year employee on a similar income might suddenly see something like:

• 住民税 (juminzei) — roughly ¥15,000 to ¥25,000 per month

So that earlier 差引支給額 (sashihiki shikyu gaku) in the mid-¥340,000s can easily fall into the low-¥330,000s or even the ¥320,000s, depending on the local tax calculation and the previous year’s actual income.

That is why so many foreigners describe June of their second year as a “salary drop” even when the company changed nothing.

Bonuses Are Taxed Differently Because the Withholding Method Is Different

A lot of foreigners assume bonus withholding is random. It is not random, but it does use a different calculation path from regular monthly salary withholding.

The National Tax Agency’s bonus withholding page explains that bonus withholding is generally calculated using a dedicated bonus table, and in the usual case the calculation starts from the previous month’s salary after social insurance deductions.

That is why:

• your bonus may feel taxed “too hard”
• the percentage may not look like the one you had in your head
• the month before the bonus can influence the withholding logic

This does not automatically mean the annual tax burden is higher than expected. It means the withholding method for bonuses is not the same as just applying the normal monthly salary line again.

How みなし残業 (minashi zangyo) Changes What the Payslip Means

If your company uses みなし残業 (minashi zangyo) or fixed overtime, your payslip can be technically correct while still hiding a bad deal.

What happens is:

• part of your compensation already includes a set number of overtime hours
• that amount may be built into salary rather than showing up as a clean extra every month
• only overtime above that threshold should trigger additional payment

So the payslip question is not only “Did I get paid?”

It is also:

• how many hours of overtime are already baked in?
• is that number written clearly in the contract?
• does actual overtime above that threshold appear separately?

This is where payslip reading overlaps with labor-law reading. If you are unsure whether the overtime part is being handled legally, our guide to Japan overtime law for engineers is the better next article.

What Is Normal on a First Japanese Payslip

These are common and usually not red flags:

• take-home pay noticeably lower than the contract headline number
• 住民税 still blank in your first year
• deductions for 健康保険, 厚生年金, and 雇用保険
• commuting allowance showing up separately from base salary
• bonus withholding that does not look like your normal salary withholding

If you only remember one thing, remember this:

a lower bank deposit than your offer letter is normal; an unexplained mismatch between the contract structure and the payslip structure is what deserves attention.

What Should Make You Ask HR Questions

These are worth checking:

• your 基本給 is lower than the contract with no explanation
• overtime hours are recorded, but overtime pay does not appear and there is no fixed-overtime structure in the contract
• a large allowance disappears or changes without notice
• social insurance is missing even though you should clearly be enrolled
• 住民税 appears earlier than you expected and no one can explain why
• your bonus line exists, but the payment basis is unclear and does not match the employment agreement

This does not mean your company is necessarily acting badly. Payroll systems are messy, and HR data entry mistakes happen. But the payslip is exactly where those mistakes become visible.

The Three Documents You Should Keep

Do not just glance at your payslip and forget it.

Keep:

• every monthly 給与明細
• your annual 源泉徴収票
• your employment contract and any compensation amendment documents

These matter for:

• visa renewals and status changes
• apartment applications
• future salary negotiations
• tax questions
• checking whether 年末調整 (nenmatsu chosei) was done properly

If you later claim deductions such as overseas dependents, those payroll and tax documents also become part of the paper trail. Our guide to overseas dependents on a Japanese tax return covers that side in more detail.

The Short Version

If your first Japanese payslip looks confusing, focus on these five checks:

1. Is 基本給 (kihonkyu) consistent with your contract?
2. Do the 支給 (shikyu) lines explain the gap between base pay and gross pay?
3. Do the 控除 (kojo) lines explain the gap between gross pay and take-home pay?
4. Is 住民税 (juminzei) blank because you are new, or present because you are now in year two?
5. If overtime or bonus amounts feel strange, do they follow the contract structure and the normal withholding rules?

Once you can answer those five questions, a Japanese payslip stops feeling like mystery paperwork and starts feeling like a monthly audit trail.

That is the real goal.

You do not need to memorize every payroll term in Japan. You just need to know which numbers are normal, which ones arrive later, and which mismatches are worth pushing back on.
