If your first Japanese payslip left you staring at a wall of kanji wondering where half your salary went, you are not alone. A Japan payslip guide for foreigners is genuinely one of the most-requested resources I get asked about — and honestly, it is a topic I wish someone had handed me in plain English years ago. Japanese payslips are dense, legally structured documents, and even fluent Japanese speakers sometimes miss what certain deductions actually mean for their take-home pay.
What Is a 給与明細 (Kyūyo Meisai)?
Your payslip in Japan is called a 給与明細 (kyūyo meisai), which literally translates as “salary breakdown.” Employers are legally required to provide one every pay cycle under the Labor Standards Act (労働基準法, Rōdō Kijunhō). Most companies issue it monthly, either as a physical slip or, increasingly, through a digital HR portal.
The document is typically divided into three main blocks:
– 支給 (shikyū) — your earnings (base salary, overtime, allowances)
– 控除 (kōjo) — your deductions (taxes, social insurance)
– 差引支給額 (sashihiki shikyū-gaku) — your actual take-home amount
Understanding the difference between these three sections is the foundation of reading any Japanese payslip confidently.
Breaking Down Your Earnings (支給)
The top section lists everything your employer is paying you before deductions. Here is what you will commonly see:
基本給 (kihonkyū) is your base salary — the fixed monthly amount in your contract. Everything else is added on top of this number.
時間外手当 (jikangai teate) is overtime pay. Under Japanese labor law, overtime is calculated at a minimum of 25% above your regular hourly rate for the first 60 hours per month, and 50% beyond that. When I’ve helped friends cross-check their payslips, this is the line that is most often underpaid without the employee even realizing it.
Other common allowances include:
– 通勤手当 (tsūkin teate) — commuting allowance, often paid as a fixed monthly amount covering your train pass
– 住宅手当 (jūtaku teate) — housing allowance, if your company offers it
– 役職手当 (yakushoku teate) — position or management allowance
Note that commuting allowances up to ¥150,000 per month are tax-exempt under current National Tax Agency (NTA) rules, which is worth knowing if you receive a large tsūkin teate.
Understanding Your Deductions (控除)
This is the section that causes the most confusion — and the most anxiety. Your deductions fall into two categories: social insurance and taxes.
Social Insurance (社会保険, Shakai Hoken)
Japan’s social insurance system is mandatory for most full-time employees. Your payslip will show contributions to:
– 健康保険 (kenkō hoken) — health insurance, typically around 5% of your standard monthly remuneration (標準報酬月額, hyōjun hōshū getsugaku), split 50/50 with your employer
– 厚生年金 (kōsei nenkin) — employees’ pension, currently set at 9.15% of your standard monthly remuneration as of 2026, again matched by your employer
– 雇用保険 (koyō hoken) — employment insurance, currently 0.6% for general employees
According to the Japan Pension Service (日本年金機構, Nihon Nenkin Kikō), enrollment in kōsei nenkin is mandatory for employees at companies with five or more staff — which means this deduction is not optional, regardless of how long you plan to stay in Japan.
Taxes
– 所得税 (shotoku-zei) — national income tax, withheld at source each month based on a provisional calculation and adjusted in December via year-end tax adjustment (年末調整, nenmatsuchōsei)
– 住民税 (jūmin-zei) — resident tax, a flat roughly 10% of the previous year’s income, collected from June of the following year. New arrivals often see ¥0 in this column for their first year, then get a noticeable jump in June — I have seen that surprise catch multiple friends completely off guard.
What Foreigners Often Get Wrong
After five years working alongside expats and international hires in Tokyo, I have noticed a few recurring mistakes.
Assuming the nenkin deduction is wasted money. Many foreigners see the kōsei nenkin line and assume they will never see that money again if they leave Japan. This is not true. If you leave Japan within two years of your last contribution, you can claim a 脱退一時金 (dattai ichijikin) — a lump-sum withdrawal payment — through the Japan Pension Service. The application window is only two years from your departure date, so missing this deadline is a costly and very common mistake.
Ignoring the year-end tax adjustment (年末調整). If your company handles your nenmatsuchōsei automatically, great — but if you have side income, rental income, or medical expenses over ¥100,000, you may still need to file a 確定申告 (kakutei shinkoku) — a self-assessed tax return — by March 15. Missing this is not just a paperwork issue; it can result in penalties.
Not checking overtime calculations. Japanese labor law requires precise overtime tracking, but errors happen. Always verify that your jikangai teate reflects the actual hours logged in your company’s attendance system.
FAQ
Why is my住民税 (jūmin-zei) ¥0 in my first year?
Resident tax is based on your previous year’s income and collected starting June of the following year. If you arrived mid-year or started working in Japan for the first time, your first full year may show no jūmin-zei deduction. Expect it to appear from the following June.
Can I get a refund on my health insurance and pension contributions if I leave Japan?
You cannot reclaim health insurance contributions, but you can claim the lump-sum pension withdrawal (dattai ichijikin) within two years of leaving Japan. The amount depends on how many months you contributed and your salary level.
My payslip is digital — is that legal in Japan?
Yes. Amendments to the Labor Standards Act now allow employers to issue payslips electronically, provided employees can access and print the document themselves.

Conclusion
Reading a Japanese payslip confidently takes a little upfront investment, but once you understand the structure — shikyū, kōjo, sashihiki — the rest is just filling in the details. The deductions that look alarming at first glance are mostly mandatory social insurance contributions that either benefit you directly or can be partially recovered when you leave.
My honest recommendation: screenshot or save every kyūyo meisai digitally. When tax season arrives, or when you eventually claim your pension withdrawal, having a complete record will save you a significant amount of stress.
Your next step: Pull out your most recent payslip, map each line to the terms in this guide, and flag anything that does not match your contract or expected hours. If something looks off, your company’s HR department (jinjibu, 人事部) is the right first contact — and now you have the vocabulary to ask the right questions.
