The Mystery of the Missing Yen

You have just finished your first full month of working in Japan. You worked hard, clocked in your hours, and eagerly awaited payday. But when you finally open that digital PDF or tear open the paper envelope containing your Kyuyo Meisai (payslip), you might feel a sudden drop in your stomach.

The number at the bottom—the amount actually deposited into your bank account—is significantly lower than the salary stated in your contract. And to make matters worse, the entire document is a maze of complex Kanji characters that Google Translate struggles to decipher.

Don’t panic. You are not being robbed, and this happens to almost every expatriate when they first start working here. Japan has a comprehensive system of social insurance and taxes that are deducted at the source. While it feels painful to see that money disappear, these deductions are paying for your world-class healthcare, your future pension, and the clean streets you walk on every day.

In this guide, we are going to demystify your Japanese payslip. We will translate the key terms, explain exactly where your money is going, and help you spot if something looks wrong. Understanding this document is the first step toward true financial literacy in your new home.

The Three Main Pillars of Your Payslip

To keep things simple, imagine your payslip is divided into three main sections. Almost every Japanese company follows this standard layout, whether you are an English teacher, an IT engineer, or a corporate executive.

1. Attendance (Kintai): This shows how many days and hours you worked.
2. Payment (Shikyu): This is the fun part—your gross earnings, including allowances.
3. Deductions (Kojo): This is the painful part—taxes and insurance.

The most important equation you need to know is:

Payment (Shikyu) – Deductions (Kojo) = Net Pay (Sashihiki Shikyu Gaku)

Your “Net Pay” is the actual cash that lands in your bank account. Let’s break these sections down one by one.

Tracking Your Time: The Attendance Section

Located usually at the top or far left of the slip, the Kintai (勤怠) section tracks your physical presence. It is vital to check this every month to ensure your overtime hours have been recorded correctly. If this section is wrong, your pay will be wrong.

Key Kanji to Look For:

• Shukkin Nissu (出勤日数): Number of days you worked.
• Kesseki Nissu (欠席日数): Number of days you were absent.
• Yukyu Nissu (有休日数): Number of paid leave days (vacation) used.
• Zangyo Jikan (残業時間): Overtime hours worked.
• Chikoku / Sotai (遅刻 / 早退): Times you were late or left early.

If you see a number next to “Chikoku” (Late) that you don’t recognize, speak to your HR department immediately. In some strict Japanese companies, being late can result in a deduction from your salary, although this is becoming less common in modern firms.

Your Gross Earnings: The Payment Section

This section, usually labeled Shikyu (支給), lists everything your company is paying you before the government takes its share. It is often split into your base salary and various “teate” (allowances).

Kihon-kyu (Base Salary)

This is your core salary. It is the fixed amount stated in your contract. Bonuses and overtime are often calculated based on this number, so a higher base salary is generally better than a lower base salary with high allowances.

Overtime Pay (Zangyo Teate)

Japan has strict laws regarding overtime. If you work more than 8 hours a day or 40 hours a week, you are generally entitled to 25% extra pay per hour. If you work late at night (after 10 PM), that rate increases. Check that your Zangyo Teate (残業手当) matches the hours listed in your attendance section.

Commuting Allowance (Tsukin Teate)

Most companies in Japan reimburse your train or bus fare. This is listed as Tsukin Teate (通勤手当). The great thing about this allowance is that it is non-taxable up to 150,000 JPY per month. It essentially passes through your payslip directly to your pocket to pay for your train pass. read our guide on Discount Travel in Japan: Rail Passes and Budget Transportation Tips to gain few travel tips.

Housing Allowance (Jutaku Teate)

Some generous companies contribute to your rent. This is fully taxable income, but it is a welcome boost.

Family Allowance (Kazoku Teate)

Traditional companies sometimes pay a small extra sum for a dependent spouse or children.

The Big Hit: Social Insurance Deductions

Now we arrive at the Kojo (控除) section. This is usually divided into two columns: Social Insurance and Taxes. We will look at Social Insurance ( Shakai Hoken ) first, as this usually takes the biggest bite out of your paycheck.

Social Insurance is mandatory. You cannot opt ​​out. However, the good news is that your employer matches your contributions 50/50. For every yen deducted from your slip, your company is paying another yen to the government on your behalf.

1.Health Insurance (Kenko Hoken)

• Kanji:健康保険
• Cost: Approx. 5% of your salary (your share).
• Benefit: This gives you your blue health insurance card. With this, you only pay 30% of your medical bills at clinics and hospitals. It also covers “High-Cost Medical Expense Benefit,” which caps your monthly medical spending if you have a serious surgery or illness.

2. Employees’ Pension (Kosei Nenkin)

• Kanji:厚生年金
• Cost: Approx. 9.15% of your salary (your share).
• Benefit: These funds your future retirement. It feels like a tax, but it is actually forced savings. If you retire in Japan, you get a monthly pension. If you leave Japan after a few years, you can apply for a “Lump-sum Withdrawal” to get a significant portion of this money back.

3. Employment Insurance (Koyou Hoken)

• Kanji:雇用保険
• Cost: Approx. 0.6% of your salary.
• Benefit: This is incredibly cheap insurance. If you lose your job, this insurance pays you a monthly allowance (Hello Work benefits) while you look for a new one. It keeps you afloat during career transitions.

4. Long-Term Care Insurance (Kaigo Hoken)

• Kanji:介護保険
• Cost: Approx. 0.9% of your salary.
• Note: You only start paying this when you turn 40 years old. It funds the care system for the elderly.

The Second Hit: Tax Deductions

After social insurance is taken out, the remaining amount is subject to taxes. There are two main taxes you will see on your slip.

1. Income Tax (Shotoku-zei)

• Kanji:所得税
• What it is: This is the national tax on your earnings.
• How it works: It is a “Withholding Tax” (Gensen Choshu). The company estimates how much you will owe for the year and takes a slice every month. Because this is an estimate, it is often not 100% accurate, which leads to the “Year-End Adjustment” in December (more on that later). The rate is progressive—the more you earn, the higher the percentage.

2. Residence Tax (Jumin-zei)

• Kanji:住民税
• What it is: This is the local tax paid to your city (ward) and prefecture.
• The Trap: Residence Tax is billed based on your previous year’s income .
  • Year 1: If you just arrived in Japan, this section will likely be 0 JPY . You feel rich!
  • Year 2: Suddenly, in June of your second year, a massive deduction appears. This is the bill for Year 1. Many expats panic because their take-home pay drops significantly in their second year. You must save for this if you are not having it deducted.

The December Bonus: Year-End Tax Adjustment

If you work for a company, December is a special month. You might notice your take-home pay is slightly higher, or you get a small refund slip. This is due to the Nenmatsu Chosei (Year-End Tax Adjustment).

Throughout the year, your company withheld Income Tax based on an estimate. In December, they calculate your exact liability. If they took too much (which they usually do to be safe), they give the excess back to you in your December or January paycheck.

This system is why most employees in Japan do not need to file a personal tax return (Kakutei Shinkoku) in February. The company handles it all for you. However, you need to submit paperwork to declare your dependents or insurance premiums to get this benefit.

Common Scenarios That Confuse Expats

“Why did my salary go down in June?”

As mentioned, this is the Residence Tax kicking in. The tax year for Residence Tax runs from June to May. If your salary increased the previous year, your tax bill jumps in June.

“I am turning 40. Why is my pay lower?”

Happy Birthday! You are now eligible for Long-Term Care Insurance (Kaigo Hoken). This extra deduction starts automatically the month you turn 40.

“My overtime pay looks low.”

Check if your company has “Fixed Overtime” (Minashi Zangyo). Some contracts include, for example, 20 hours of overtime in your base salary. You only get paid extra if you work more than 20 hours. This is common and legal, but you should be aware of it. Check more on Freelancing in Japan: How to Go Solo (Visa & Tax Tips).

How to Save Money Based on Your Payslip

believe it or not, understanding your payslip can help you save money.

1. Check Your Dependents

Income tax is lower if you have dependents (spouse, children, or elderly parents). Even if your parents live overseas, you might be able to claim them as dependents if you send them money regularly. This reduces your “Shotoku-zei” (Income Tax) immediately.

2. iDeCo (Individual Pension)

If you contribute to an iDeCo plan, the entire contribution is tax-deductible. You can report this to your employer during the Year-End Adjustment, and they will refund you the tax savings. It is one of the most powerful ways to lower the tax numbers on your payslip. Check our guide on NISA and iDeCo Guide: Tax-Advantaged Investment Accounts for Expats.

3. Furusato Nozei

While this doesn’t lower the total amount you pay, it redirects your Residence Tax. Instead of paying it all to your boring city hall, you prepay it to rural cities that send you meat, rice, and fruit. It makes paying that “Jumin-zei” line on your payslip feel much more rewarding.

Digitization of Payslips

In the past, everyone received a physical paper envelope. Today, many Japanese companies use online portals like “SmartHR” or “Freee” to deliver payslips.

These systems are convenient, but they often lock you out once you leave the company. Pro Tip: Always download the PDF of your payslip every month and save it to your personal cloud storage (Google Drive, Dropbox). Read more about Getting a Mortgage in Japan: Can Foreigners Get Home Loans?
