How to Resign Properly from a Japanese SSW Job — Notice Period, Resignation Letter, Employment Certificate, and Visa-Safe Timing

Resigning from a Japanese SSW job is not as simple as walking out and starting somewhere new. There are notice-period rules to respect, specific Japanese documents you must write or request, items you must return, and — uniquely for SSW workers — visa implications that can put your right to stay in Japan at risk if the transition is handled poorly.

This guide explains the full resignation process for SSW workers in Japan: how much notice you legally must give, how to write a clean Japanese resignation letter (taishokutodoke), how to ask for the employment certificate (taishoku shoumeisho) you'll need for your next visa, what you must return on your last day, how to time the resignation so your visa stays safe, and the common mistakes that get foreign workers in serious trouble.

Before You Decide to Resign — Things to Check First

Before announcing anything:

• Re-read your employment contract. Look for the notice-period clause (often 30 or 60 days) and any non-compete or post-employment restrictions.
• Check your unused paid leave balance. Paid leave is a legal leave entitlement, and using it during the notice period can protect your income while you transition. Payment for unused leave at termination is not generally required unless the employer agrees or company policy provides for it, so do not assume it will be bought out.
• Check your bonus eligibility cutoff date. Resigning two weeks before a bonus calculation date often forfeits the bonus.
• Have your next step lined up: a new job offer, return to your home country, or a realistic job-search plan. Immigration Act Article 22-4, Paragraph 1, Item 6 is not an automatic 3-month grace period — it is a revocation-risk rule if you stop the activity of your residence status for 3 months or more without justifiable reason (and under Item 5, your status can be revoked even sooner if you take up an unrelated activity).
• Confirm your visa timeline. If you are switching to a new SSW employer, you must obtain approval for a change of status of residence before you can start working for the new employer — even a move within the same SSW field requires this because the contracting organization changes. The 14-day contract-organization notification is an after-the-fact report and does not by itself authorize new-employer work. Discuss with your registered support organization, placement agency, or an immigration professional before you resign.
• Update your Residence Card address if your address is no longer current. Immigration checks the latest registered address.

Notice Period — What the Law Actually Requires

Japan's Civil Code Article 627 sets the basic rule: for an employment contract with no fixed term, either party may give notice of termination, and the employment generally ends two weeks after the notice. In practice, however, you should still check your work rules and contract procedures and avoid creating unnecessary conflict over timing.

However, in practice:

• Many employment contracts specify a longer notice period — 30 days, 60 days, or even 90 days. While the Civil Code's 2-week rule is sometimes argued to override contractual notice for monthly-paid employees, the polite and safe default is to give the notice your contract specifies.
• 30 days' notice is the practical Japanese norm. Giving less puts your employer in a difficult position and damages your reference for the next job.
• Fixed-term contracts generally cannot be ended early without "unavoidable reasons" — check your contract terms and consult a labor consultation hotline if unsure. Some SSW employment contracts are fixed-term and the contract period may be coordinated with the worker's period of stay, so always check whether your own contract is fixed-term or indefinite-term. Note one important exception: under Labor Standards Act Supplementary Provision Article 137, where a fixed-term employment contract is for a period longer than one year, a worker may generally resign at any time after one year has passed from the start of the contract, except for certain contracts such as those involving highly specialized knowledge or post-retirement re-employment arrangements.
• If you are still in your trial period, the notice rules and dismissal protections are slightly different but the polite norm still applies.

Recommendation for SSW workers: give at least 1 month's notice in writing, ideally 1.5 to 2 months, especially if you want a clean reference and a smooth visa transition.

Who to Tell, and in What Order

Order matters. Telling the wrong person first damages trust.

1. Your direct supervisor first. In private. In person if possible; video call if remote. Do not announce by email or chat as the first step.
2. HR after the supervisor agrees on a date. HR formalizes the paperwork, but the supervisor is the first relationship to manage.
3. Your team after HR confirms. Usually your supervisor handles the announcement; you don't tell co-workers individually before that.
4. Your registered support organization or placement agency: tell them as soon as the resignation date is fixed, because they will likely help with visa-related paperwork.
5. Customers / external contacts: only after HR has approved the messaging.
6. Immigration: see the Notification to Immigration section below.

Resignation Letter — How to Write One

Japan distinguishes between two similar documents:

• 退職願 (taishoku-gan, resignation request): a request to be allowed to resign. Used when you are still negotiating the date with the employer.
• 退職届 (taishoku-todoke, resignation notice): a unilateral notice that you are resigning. Used once the date is set.

For SSW workers, the simpler 退職届 is usually fine. Standard structure (one A4 page, vertical writing by tradition, but horizontal is now widely accepted):

退職届

この度、一身上の都合により、
令和[X]年[X]月[X]日をもって退職いたします。

令和[Y]年[Y]月[Y]日
所属：[Department]
氏名：[Your name] 印

[Company name]
代表取締役 [President's name] 殿

Key points:

• Title: 退職届 centered at the top.
• Reason: simply "一身上の都合 (ishin-jou no tsugou, personal reasons)". You do not need to give a detailed reason. This is the standard phrasing.
• Resignation date: the date your last working day will be, agreed with your supervisor.
• Date of writing: today's date.
• Department and name with your seal (or signature if you don't use a seal).
• Addressed to the company president, not to your supervisor.

Print it, sign/stamp it, put it in a plain white envelope marked "退職届" on the front, and hand it to your supervisor or HR in person. Keep a copy for your records.

The Verbal Resignation Conversation

The conversation matters as much as the paperwork. A reasonable script:

1. Ask for 15 minutes in private.
2. State the fact: "いつもお世話になっております。実は、一身上の都合により、退職を決意しました。[X]月[X]日をもって退職させていただきたいと考えております。" (Thank you as always. The fact is, I've decided to resign for personal reasons. I would like to resign as of [date].)
3. Thank them for the experience: "これまでご指導いただき、本当にありがとうございました。" (Thank you very much for your guidance.)
4. Offer to help with a smooth handover: "引き継ぎはしっかりさせていただきます。" (I will properly handle the handover.)
5. If asked for a reason in detail, be brief and forward-looking. "I want to develop my career in [field]" or "I want to be closer to family" is enough. Avoid criticism of the company, your supervisor, or co-workers even if true.

Documents You Must Receive From the Employer

Before or shortly after your last day, confirm which of the following documents you need. Some are issued only on request, some are issued automatically or later, and some are issued only when relevant (e.g., for unemployment benefit procedures).

The employment certificate is the most important for SSW transitions. By law (Labor Standards Act Article 22), the employer must issue it on request and must include only the items you specify (period of employment, type of work, position, salary, reason for separation) — the employer may not add items you did not request. If the employer refuses to issue it after you request it, consider consulting the local Labor Standards Inspection Office or a labor consultation service.

What You Must Return on Your Last Day

• Any employer-issued health insurance card or eligibility confirmation document for you and your dependents — note that new issuance of the traditional 健康保険証 ended in December 2024 and most workers now use a My Number health insurance card or a 資格確認書.
• Company ID card, security pass, time card.
• Company-issued phone, laptop, tools, uniform, name card.
• Keys to the office, dorm (if leaving), or company vehicles.
• Any documents containing confidential information.
• Manuals or training materials issued by the company.

If you live in a company dorm, clarify your move-out date and rent calculation in advance. If you keep the dorm room briefly after resignation, the rent or usage fee may change depending on the company dorm rules and your agreement with the employer, so confirm this in writing before your last day.

Final Pay and Unused Paid Leave

Two important entitlements:

• Unused paid leave: You can either take the leave during your notice period (the most common option) or, where the employer agrees and policy allows, have it paid out. Note that Japanese employers are not legally required to pay out unused paid leave on termination unless local company policy says so — if you want to use it, use it during the notice period.
• Final salary: under Labor Standards Act Article 23, if you (as the person entitled) request payment, the employer must pay outstanding wages within 7 days of that request; otherwise it is paid on the normal payday. Bonus accruals depend on the employer's policy.

Common practice: agree with your supervisor on which days you will use paid leave, work the rest of the notice period, and receive the final salary on the next normal payday.

Visa Implications — Critical for SSW Workers

This is where SSW workers face risks that other employees don't:

• Your SSW status allows you to work only within the designated SSW activity, field, and accepting organization shown in your Immigration documents. When you leave that employer, you generally cannot simply start working for another employer until the required Immigration procedure is completed.
• Article 22-4, Paragraph 1, Item 6 of the Immigration Control Act states that your status can be revoked if you stop the activity of your status of residence for 3 consecutive months or more without justifiable reason. This is a risk-side rule, not an automatic 3-month grace period. Under Item 5 of the same article, your status can be revoked even before 3 months pass if you are not performing your visa activity and are instead engaging in (or preparing to engage in) a different activity without justifiable reason — so do not start unrelated work while between SSW jobs.
• In practice, SSW workers who actively look for a new employer in the same field, and report the situation to Immigration / their registered support organization, are normally allowed time to find new work. But the clock is running.
• You must file the notification concerning your contracting organization within 14 days of the relevant event (e.g., end of the employment contract). Submit by post, in person at a regional Immigration office, or online via the Immigration electronic notification system. (Separately, the employer/accepting organization also has its own SSW notification duty within 14 days — but that does not remove your personal obligation.)
• If you have a new SSW employer ready, you must obtain approval for a change of status of residence before starting work — even within the same SSW field — because your SSW status is tied to the specific accepting organization, field and work named in your Immigration designation documents. Processing time varies by case and Immigration office, so apply as early as possible and do not start the new job until it is approved.
• If you are leaving Japan permanently, the timing is simpler — but file the dismissal/resignation notification and consider the pension lump-sum withdrawal.

Moving On — Notification to Immigration

Within 14 days of the relevant event (such as the end of your employment contract), file the notification concerning your contracting organization with the Immigration Services Agency. This is a free, simple form. You can submit:

• By post to the designated Immigration notification address (check the latest Immigration Services Agency instructions for the current address).
• In person at a regional Immigration Services Bureau or branch office that accepts the notification.
• Online via the applicable Immigration online or e-notification system, if you meet the latest system requirements.

You should also notify the accepting organization and, if support has been outsourced, your registered support organization (for SSW Type 1) of the resignation. Depending on the situation and support arrangement, they may coordinate support, guidance, or procedures related to transitioning to a new employer, returning home, or other next steps.

When you start the new SSW employer (after the change of status of residence has been approved), file the contracting-organization notification again within 14 days of joining (this time noting the new employer).

What to Do If You Get a Counter-Offer

It is common for Japanese employers to make a counter-offer when a useful employee resigns — a salary bump, a promise of a promotion, additional flexibility, etc.

Practical advice:

• Be polite but firm if your decision is made. "ご配慮ありがとうございます。私の決意は変わりません。" (Thank you for your consideration. My decision has not changed.)
• Consider carefully if the counter is genuine. Sometimes counter-offers are short-term retention tactics; the underlying reasons you wanted to leave may not actually change.
• Don't use the counter-offer as a bluff. If you accept the counter and stay, but later resign anyway when the next opportunity comes, trust is broken on both sides.
• If you accept the counter and stay, get the new conditions in writing as a revised employment contract or contract amendment. Verbal promises evaporate.

Mistakes That Can Create Problems for SSW Workers

• No notice / walking out. Damages your reference, makes visa transition harder, and in some cases can be considered breach of contract.
• Resigning by chat, text, or email only. Always have an in-person or video conversation first.
• Skipping the 14-day notification to Immigration. This is a legal obligation.
• Letting the Article 22-4 revocation-risk period approach without a plan or justifiable reason. Talk to your support organization or placement agency early.
• Not asking for the employment certificate. Your next visa application and next employer will need it.
• Forgetting the withholding tax slip. Your next employer needs it for year-end adjustment.
• Not returning company items. This can lead to claims for return or damages, but the employer cannot automatically withhold wages in violation of the wage-payment rules.
• Burning bridges with criticism when leaving. Japan's foreign-worker community is small; word travels.
• Negotiating a counter-offer dishonestly — accepting and staying with no intention to stay long.
• Accepting a new offer before filing the change-of-status application, then having the application delayed and being unable to start on the promised date.

Frequently Asked Questions

Summary

Resigning from a Japanese SSW job properly is more procedural than emotional. Give clean notice in writing, have the right paperwork in hand on your last day, file the Immigration notification within 14 days, and have your next step lined up before you walk out the door. Done well, you keep your reference, your visa, and your future doors open in Japan. Done poorly, you can lose all three.
