Hiring in Japan with an EOR: costs, rules, and best providers (2026)

If you set up your own entity in Japan, the first regulatory obligation you face before you can hire a single person is compliance with the shugyo kisoku requirement: once you employ 10 or more workers at a workplace, you must draft written work rules covering hours, wages, and discipline, then file them with the local Labour Standards Inspection Office. Those rules become part of your employees' terms and conditions, and changing them to an employee's disadvantage requires a formal process and, in practice, genuine consultation. An Employer of Record (EOR) absorbs that obligation entirely. The EOR already has compliant work rules in place, handles social insurance enrollment and payroll withholding from day one, and manages the overtime recording duties that Japanese law imposes on every employer. Entity setup in Japan typically takes three to six months; an EOR hire can be live in three to five days.

On the economics, the employer social contribution rate of around 15.7% is the primary cost variable to model alongside base salary. Published EOR fees in Japan run from $99 to $699 per employee per month across the 38 providers currently active in this market. For a single hire or a small team being tested before a longer commitment, the EOR fee is almost always cheaper than the legal, accounting, and administrative overhead of maintaining a local entity. The crossover point depends on headcount and how long you expect to operate, but in my experience the entity route rarely makes financial sense in Japan until you have a team large enough to justify a dedicated local HR and legal function.

On contractors: Japan's courts look at the substance of how work is performed, and workers who are directed, integrated into regular operations, and economically dependent on one client are frequently reclassified as employees regardless of what the contract says. Given how strictly Japanese courts treat employment protections, a misclassified contractor who later claims employee status can expose you to unpaid social insurance contributions and, more seriously, the full weight of Japan's dismissal protections. For anything resembling an ongoing working relationship, an EOR or entity structure is the appropriate vehicle.

Japan has several compliance obligations that consistently catch foreign employers off guard. Each of the items below comes up repeatedly when companies enter this market without local guidance.

Dismissal is genuinely difficult, not just procedurally inconvenient

Japanese law applies a four-factor test to any dismissal, and courts have consistently found that terminations for ordinary underperformance or restructuring are an abuse of the right to dismiss unless the employer can show it exhausted alternatives such as redeployment and performance improvement plans. The 30-day statutory notice period is the easy part. The harder part is building the documented record that makes a dismissal legally defensible in the first place. Foreign employers who assume they can exit an underperforming hire the way they would in a common-law jurisdiction are routinely surprised by how much process is required before a separation is safe.

Bonuses and fixed overtime can become de facto base salary

Large twice-yearly bonuses and fixed overtime allowances are a standard part of Japanese compensation packages, but once they become established practice, courts may treat them as part of core working conditions rather than discretionary payments. Cutting or removing them without employee consent can give rise to claims of unreasonable disadvantage or constructive dismissal. Foreign employers who budget bonuses as a flexible line item and expect to reduce them in a difficult year are often caught out when that expectation meets Japanese employment law.

Social insurance enrollment is mandatory at low thresholds

Health insurance, pension, and related social insurance schemes apply once employees meet relatively low thresholds of working hours and contract duration. Part-time staff working 20 hours per week at companies above a certain size must generally be enrolled. Failure to enroll triggers back payments and penalties from the authorities. Foreign employers used to treating part-time or short-contract staff as outside the social insurance system find that Japan does not give them that flexibility once the thresholds are met.

Overtime premium rates are mandatory and cannot be waived

The Labour Standards Act sets minimum premium rates for overtime, late-night work (between 10 p.m. and 5 a.m.), and holiday work that no employment contract or salary clause can override. Employers must keep accurate working-hour records for all staff, including white-collar employees that a foreign employer might assume are exempt. Informal all-inclusive salary arrangements do not eliminate the obligation to pay statutory premiums, and the recording duty itself is a compliance burden that requires systems and processes from the moment you hire.

Written work rules must be filed with the government once you reach 10 employees

Any workplace with 10 or more regular employees must prepare written work rules covering hours, wages, discipline, and other core terms, then submit them to the local Labour Standards Inspection Office. These rules carry legal weight: they form part of the employment conditions, and changes that disadvantage employees require a formal process. Foreign employers who treat internal HR policies as internal documents are surprised to find that Japanese law requires those policies to be formalised and submitted to a government office at a headcount threshold that most growing teams cross quickly.
