A joining pledge, often called a seiyakusho in Japan, records promises the employee makes about matters such as company rules and information handling. Before filling in your name and address, read who is making each promise, what it covers, and how long it applies.
Documents with this name can cover different subjects, including your intention to join, confidentiality, and company equipment. This guide explains how a candidate can review, complete, and submit an employer's joining pledge in Japan. It is not a contract template for employers.
What does a joining pledge contain?
Possible subjects include compliance with work rules, handling information learned at work, use of equipment, and statements made during recruitment. Check every page and attachment supplied by your employer to establish what your document actually covers.
Receiving a document and agreeing to its contents are separate steps. If a clause is unclear, identify the question rather than skipping it because someone says the document is required for onboarding.
A pledge that confirms your intention to join may also serve a purpose similar to an offer acceptance form. Read the wording to determine whether it concerns workplace conduct, acceptance of employment conditions, or both.
Joining pledge, guarantor form, and employment contract: the differences
Document | Main subject to check | Whose agreement matters |
|---|---|---|
Joining pledge | The employee's promises about rules and information handling | The employee |
Employment guarantor form | The matters and extent of responsibility assumed by a guarantor | The employee and guarantor separately |
Employment contract | Working conditions agreed between the parties | The employer and employee |
A single document may combine several subjects. If your pledge contains a guarantor signature field or clauses guaranteeing compensation, do not treat it as a form completed only by you. See our guide to employment guarantors, maximum liability, and guarantee periods for that subject.
For pay, workplace, and other employment conditions, consult our guide to reading a working conditions notice. Signing a pledge does not resolve unanswered questions about those conditions.
How to complete the employee fields
Follow the instructions for the employer's designated form. Before replacing it with your own template, confirm the submission and correction procedures.
1. Addressee, name, and address
Check the employer's formal name and any printed representative's name. Your name and address should match the information used for onboarding. If you expect to move, ask whether to enter your current or future address; do not guess an address that has not been decided.
If you use a previous surname or have changed your name, check how the employer will register and match your information. The person who has reviewed the contents should sign using the required method.
2. Document date and expected starting date
Establish whether the date means the completion date, signature date, or the date the pledge takes effect. Do not confuse it with a separate starting-date field.
Fictional example: name, Taro Yamada; address, the current registered address; signature date, October 20, 2026; expected start, November 1, 2026. Replace these examples with your actual information and the employer's instructions. Do not backdate a signature simply to match another date without checking with the employer.
3. Signature, seal, and electronic procedures
Check whether a handwritten signature, typed entry, or seal is required. Do not assume that a registered seal or seal registration certificate is necessary. If requested, ask why it is needed and how to submit it.
For an electronic procedure, identify the document you are agreeing to when you confirm and whether you can save a completed copy. Sending a photograph of a paper form and completing an electronic signature service are different submission methods.
4. Blank fields, attachments, and corrections
Distinguish employee fields from employer and guarantor fields. Follow instructions for fields that do not apply; do not fill an unclear blank by guessing.
For a mistake, confirm whether to use a correction line, obtain a replacement, or request a new electronic form. If you want to change a substantive clause, discuss agreement on the wording separately from correcting a typing error.
Five points to read before signing
These are editorial prompts for reviewing a document, rather than a universal test of whether its clauses are lawful.
Area | Question to ask |
|---|---|
Scope | Which actions and information does the promise cover? |
Duration | Does it apply only during employment or after leaving too? |
Referenced rules | Can you review the work rules or information policies it refers to? |
Responsibility | Does it specify penalties or a fixed compensation amount? |
Procedure and records | Who receives it, and which documents should you keep? |
Confidentiality: establish what counts as confidential
Read the scope and handling requirements for client information, unpublished technology, and internal materials. If rules concern personal devices, cloud storage, taking materials home, or returning and deleting them when you leave, ask how those rules operate in practice.
A general promise not to disclose confidential information may not tell you where you can save a work file. Establish whom to ask when a work task presents an uncertain situation.
Read side-job rules separately from restrictions after leaving
A procedure for reporting a side job and a restriction on work after leaving are different matters. Check the activities, duration, geographical scope, exceptions, and consultation process. Japan's Ministry of Health, Labour and Welfare explains the relationship between side jobs, confidentiality, and competition in its guide to side jobs and working conditions.
If wording appears to prevent a future job in the same industry, the document's name alone does not establish whether the restriction is valid. Ask how its scope relates to your duties; if you remain uncertain, show the actual wording to an appropriate adviser.
Examine penalties and compensation clauses before agreeing
Article 16 of Japan's Labour Standards Act prohibits an employer from setting a penalty or predetermining compensation for breach of an employment contract. See the ministry's FAQ on predetermined penalties.
If a clause says you must pay a fixed amount for leaving within a certain period, ask about its wording and basis. This rule does not mean that responsibility for every actual loss disappears. Distinguish a predetermined penalty from a claim concerning particular damage.
What if you disagree with the pledge or do not want to submit it?
Rather than leaving the form unanswered, tell the employer which clause raises a question and when submission is due. Specific questions, such as the scope of a particular clause or an unavailable referenced policy, make a request for explanation or revision clearer.
Example message: “Before signing the joining pledge, I would like to clarify clause [number]. Could you explain the scope of confidential information and how long the clause applies after employment ends? I would also like to review the policies it refers to. I understand the submission deadline is [date]; could we discuss how to complete the procedure after these points have been clarified?”
This is a fictional example. Replace its clause number and date with the actual details. Refusal does not automatically have one universal consequence: check the employer's response and the circumstances of your recruitment and contract.
Do not remove clauses without agreement or sign on behalf of a guarantor. If discussion does not resolve the issue, take the documents and relevant correspondence to a Comprehensive Labour Consultation Corner or another suitable adviser.
Checklist before submission
- You have reviewed the latest form, its attachments, and referenced rules.
- Your name, address, dates, and expected start match the actual information.
- You have distinguished employee, employer, and guarantor fields.
- Unclear clauses have been explained, and necessary changes discussed.
- You know the recipient, submission method, deadline, and how to save a copy.
For the wider set of documents, use our job-change paperwork checklist. Keep your pledge as a record of obligations you understand, rather than simply another item marked as submitted.
Frequently asked questions
Do I need to write my own joining pledge?
First check whether the employer has a designated form. Use it if supplied, and discuss any proposed replacement wording with the responsible person.
Does signing make every clause valid?
A signature does not automatically make a clause that conflicts with the law valid. However, disagreeing with a clause and establishing that it is legally invalid are different matters. Ask about the specific wording.
What if a pledge and guarantor form are supplied together?
Review your own promises separately from the guarantor's responsibility. Give the guarantor all relevant pages so they can understand the terms before completing the procedure.
Completing a joining pledge means both filling in the fields and understanding what you promise. Clarify questions before signing and retain a copy you can consult after joining.
