Key Points to Check on Your Employment Contract — Always Confirm Before You Sign
Once you sign, "I wasn't told that" rarely works afterward

"Just sign here for now," I was told, and I wrote my name without really reading what it said.
Arif (25), from Bandung, Indonesia, was handed a stack of documents on his first day. They were all in Japanese, and there was no time to read everything on the spot. Urged by the person in charge with "everyone does it this way," he signed as told.
Three months later, Arif began to feel "this is different from what I was told." At the interview, he'd heard "weekends off," but Saturday shifts were on his schedule. He'd been told there was no overtime, yet there was two hours every day. But when he looked back at the contract, there in small print were the words "shift system" and "fixed overtime included." It's the signed document, not the verbal promise, that becomes the standard. Arif couldn't argue back.
In Japan, signing an employment contract (Notice of Working Conditions) means "I agreed to work under these conditions." Even if you later say "I wasn't told" or "I didn't read it," the content of the signed document often takes priority.
Put the other way around: if you check carefully before signing, you can protect yourself. Companies have a legal obligation to show important working conditions in writing (the Labor Standards Act). We've put together where to look in that document, in a checklist.
Documents stating your working conditions include the "Notice of Working Conditions" (a document the company is obligated to issue) and the "employment contract" (a contract that labor and management sign) — and many documents serve as both. Note that creating an employment contract itself is not a legal obligation, but the written disclosure of working conditions is the company's obligation. Before you sign, be sure to check the following.
01.Check the contract period and whether there's "renewal and a renewal cap"
First check "whether there is a fixed term (fixed-term)" or "not (open-ended / permanent employee)." For a fixed-term contract (e.g., a one-year contract), the document should clearly state "whether it will be renewed," "what the renewal criteria are," and "whether there is a cap on the number of renewals." From April 2024, whether there is a renewal cap also became a matter that must be disclosed for fixed-term contracts. So you don't end up thinking "I thought I could work here forever, but it ended in a year," always check the term and renewal conditions.
02.Look at the "place of work and job content," and their "scope of change"
Your place of work and the content of your work are written here. From April 2024, not only the place and work right after joining, but also the "range within which they could change" due to future reassignments and the like, must be disclosed. Check ranges such as "I thought I'd work in Tokyo, but the contract allows transfers nationwide" or "I expected office work, but I could also be assigned to the manufacturing floor." This is especially important for foreign nationals, because it also relates to whether the work content falls within the range allowed by your residence status.
03.Check working hours, breaks, days off, and whether there's overtime
Check the start and end times, break times, days off (which days, how many days a week), and "whether there is overtime beyond the prescribed working hours." Even if you heard "weekends off" at the interview, if the contract says "shift system," whether you work weekends depends on the shift. If the verbal explanation and the written document don't match, always confirm before signing by saying, "At the interview I was told this…"
04.[Most important] Check the "breakdown" of wages and the payment method
Check how much the base salary is, whether fixed overtime pay (deemed overtime) is included, the various allowances (commuting, housing, etc.), the closing date and payday, and deductions (taxes, social insurance). Whether the breakdown of a "monthly salary of 250,000 yen" includes fixed overtime is especially important (see also our article on how to read a job listing). Note that "matters concerning pay raises" must be disclosed, but it doesn't have to be in writing, so if it isn't written, confirm it verbally.
05.Check the matters concerning resignation and dismissal
"In what cases you can quit (the resignation procedure)" and "in what cases you can be dismissed (the grounds for dismissal)" are also matters that must be disclosed in writing. Check how many days in advance you must give notice to quit, and how things work during the trial period. Knowing this lets you protect your rights when you want to quit, or when you're about to be unfairly dismissed.
06.Check enrollment in social insurance and employment insurance
If you're a full-time / regular employee, enrollment in health insurance, employees' pension, employment insurance, and workers' accident compensation insurance is the company's obligation. Check whether the contract or notice says "social insurance enrollment." If there's no mention, or you're told "enroll in National Health Insurance yourself," it may be an illegal situation where you're not enrolled in the insurance you're supposed to be in. Social insurance is an important system that prepares you for illness, injury, and your future pension.
07.Always ask about words you don't understand before signing. If the document and reality differ, you can terminate
Don't sign while you don't understand Japanese technical terms. Asking "Could you tell me what this word means?" is not rude at all. If anything, you'll be seen as someone who confirms things properly. The Ministry of Health, Labour and Welfare also provides multilingual "model Notices of Working Conditions." Note that if the disclosed working conditions differ from reality, the worker has the right to terminate that contract immediately (Article 15 of the Labor Standards Act). The iron rule for signing is "after reading, understanding, and being satisfied."
After that experience, on his next job change Arif checked the contract line by line and asked HR about anything he didn't understand before signing. Being able to confirm "weekends off, no fixed overtime, full social insurance" in writing let him work with peace of mind. He told us, "Sign only after you've read and are satisfied. That's the one thing I make sure to keep." When you have concerns about the content of a contract, don't rush to sign — you can consult the Labor Standards Inspection Office or the foreign-worker consultation desk at Hello Work (free).
