Notice Periods and Start Dates When Hiring in Japan

International companies hiring their first people in Japan are often surprised by one thing after the offer is signed: how long it takes for the new hire to actually start. A candidate who accepts in early spring may not be available until summer. That gap is rarely a sign of low commitment. It usually reflects how resignation, handover, and leave work in Japanese companies.

This guide explains the main factors behind that gap and how to plan around them. It covers general practice, not legal advice. For anything that touches employment contracts or work rules, confirm the details with a qualified Japan labor attorney or a sharoushi (a licensed labor and social insurance consultant).

The legal minimum vs. what actually happens

Japanese law sets a fairly short statutory minimum for an employee on an open-ended contract to resign. In practice, though, that minimum is rarely what determines a start date. Several other things tend to matter more:

• The current employer's work rules (shugyo kisoku). Many companies' work rules ask employees to give notice well ahead of the statutory minimum, commonly around a month and sometimes longer for senior staff. How enforceable these clauses are is a legal question. But most candidates follow them anyway, because they want to leave on good terms.
• Fixed-term contracts. Candidates on fixed-term contracts (common for contract staff and some foreign employees) may face different rules about leaving before the term ends. Ask about their contract type early.
• Professional norms. Leaving abruptly is widely seen as damaging to someone's reputation, and Japanese industries can be small and well connected. Most experienced professionals will plan a respectful exit even when they could legally leave sooner.

For planning purposes, assume the notice period your candidate describes is the real constraint. Don't treat the legal minimum as the timeline.

Handover (hikitsugi) takes real time

In many Japanese workplaces, a thorough handover is expected before someone leaves. The departing employee documents their work, introduces a successor to clients and partners, and sometimes stays on until a replacement is hired or trained. For client-facing roles like sales, account management, and partnerships, this can involve farewell visits or calls to key accounts.

Candidates coming from these roles may say their manager has asked them to stay "until the handover is complete." That timeline is often negotiated inside the current employer, so the candidate may not be able to give you a firm date right away. Keep in touch during this period instead of going quiet after the offer.

Using remaining paid leave before leaving

It is common in Japan for employees to use their remaining paid annual leave before their official last day. Unused leave has often built up, because many employees don't take all of their entitlement during the year. So a candidate may finish their handover, stop coming to work, and spend several weeks on paid leave while still technically employed by their current company.

This matters for two reasons:

1. The formal start date moves later. The candidate usually can't join you until their employment has formally ended, even if they are no longer doing any work there.
2. Dual employment questions. Starting with you while still on the books at the old employer can create issues with employment terms, social insurance enrollment, and non-compete or side-job clauses. Check with your advisor or Employer of Record before agreeing to any overlap.

Bonus timing shapes when people move

Many Japanese employers pay bonuses once or twice a year, often in summer and at the end of the year. These bonuses can be a large share of total annual pay. As a result, many candidates prefer to resign after a bonus has been paid rather than give it up.

You'll often see this in negotiations. A candidate may ask to push their start date past a bonus payment, or ask you to make up for a bonus they would lose by leaving early. Neither request is unusual. Decide in advance whether you'd rather wait or offer a sign-on payment to make up the difference. If you do offer one, get advice on how to structure it under your Japan payroll setup.

Fiscal year and April starts

Many Japanese companies run their fiscal year from April to March, and April is traditionally when new graduates join and internal transfers happen. Some mid-career candidates like to leave at the end of a fiscal year or a quarter, once their current year's targets are closed. This is a preference, not a rule. But if a candidate is aiming for a specific month, ask whether it's tied to their employer's fiscal calendar.

A realistic planning window

Put all of this together and the time from signed offer to first day for an experienced mid-career hire in Japan is often measured in months, not weeks. Senior hires tend to take longer, because they usually have more responsibilities to hand over and more leave built up.

When you plan headcount for Japan:

• Start sourcing earlier than you would elsewhere. If you need someone in seat by a certain quarter, work back from a realistic notice-plus-handover window, not just the time needed to find and close a candidate.
• Ask about timing in the first interview, not after the offer. Ask about their current notice terms, contract type, expected bonus dates, and any leave they plan to use. This avoids surprises late in the process.
• Get your own setup ready in parallel. Use the waiting period to set up your hiring vehicle (an EOR or your own entity), payroll and social insurance enrollment, equipment, and onboarding plan. For foreign candidates, also start any visa work. A long notice period is only a problem if your side isn't ready either.

Keeping candidates warm during the gap

A long gap between acceptance and start creates risk. The candidate's current employer may make a counteroffer, or another company may approach them. A few habits help:

• Stay in regular, low-pressure contact. A short check-in every few weeks, updates on the team, or an informal meeting with future colleagues helps the candidate feel committed.
• Send onboarding materials early, where appropriate. Don't expect real work before their start date, though, and be careful about anything that could look like they're working for you while still employed elsewhere.
• Put the start date and key terms in writing once they're agreed, so both sides have the same expectations.

Key takeaways

• The statutory minimum notice period in Japan rarely determines when someone actually starts. Work rules, handover norms, unused paid leave, and bonus timing usually matter more.
• Plan for an offer-to-start window of months for experienced hires, and longer for senior roles.
• Ask about notice terms, contract type, bonus timing, and leave early in the process.
• Use the waiting period to get your entity or EOR, payroll, visa, and onboarding ready.
• Confirm anything contractual, including dual-employment questions and sign-on payments, with a qualified Japan labor attorney or sharoushi.
