Hiring your first employee in Japan changes the administrative character of a business quite quickly. Payroll, insurance, employment documentation, working-hour records and ongoing labour compliance all become part of running the company.
For foreign business owners, some of the difficulty comes from applying assumptions formed in other countries. Employment practices that are routine elsewhere may work differently under Japanese law, and informal arrangements become increasingly risky once someone is working regular hours under the direction of the company.
At Nippon Bridge, we often deal with these issues when helping overseas owners establish or operate businesses in Japan. A little planning before recruitment usually saves considerably more work after the employee has started.
Budget Beyond the Advertised Salary
An employee earning ¥4 million per year costs the company more than ¥4 million.
Employers contribute toward health insurance, Employees’ Pension Insurance, employment insurance and workers’ compensation insurance. JETRO uses approximately 15% of annual wages as a general estimate for the employer’s share of labour and social insurance premiums, although the actual percentage varies with factors including location, industry and the employee’s circumstances.
That makes a ¥4 million salary a useful starting point for budgeting, rather than the finished figure. Recruitment costs, commuting allowances, equipment, software, payroll administration, professional support and any bonus arrangement also need to be considered.
Employees’ Pension Insurance alone is charged at 18.3% of the applicable standard remuneration, with employer and employee generally paying half each. Health insurance rates vary by prefecture, and additional insurance can apply according to age and employment circumstances.
For a small company, these additions can make the difference between an affordable hire and an uncomfortable monthly commitment. It is worth calculating the full annual employment cost before deciding what salary to advertise.
Employment Terms Need to Be Clear Before the Start Date
Japanese employers must provide employees with specified employment conditions when entering into the employment relationship. Important matters include the contract period, workplace and duties, working hours, holidays, wages and termination conditions. Many of these conditions must be provided in writing or through an accepted electronic method.
Rules introduced in 2024 also expanded the information employers need to provide regarding possible changes to workplace and duties, as well as renewal limits for fixed-term contracts.
For a foreign-owned business, preparing these documents properly also forces several useful decisions early: Who supervises the employee? Where can they work? Is remote work permitted? How are expenses approved? What happens during busy periods? How will performance be reviewed?
Those questions tend to become much harder once the employee has already developed their own understanding of the arrangement.
A bilingual employment agreement can also be useful when either the employee or company management is more comfortable working in English. The Japanese version should still be prepared carefully and should accurately reflect the actual working arrangement.
Working Hours and Overtime Need Their Own System
Japan’s statutory working-hour framework generally sets the limit at eight hours per day and 40 hours per week. A company intending to have employees work beyond statutory hours or on statutory days off generally needs a labour-management agreement commonly known as a 36 Agreement, filed with the Labour Standards Inspection Office.
Overtime also carries statutory premium rates. Work beyond statutory hours generally attracts at least a 25% premium, statutory holiday work at least 35%, and late-night work between 10 p.m. and 5 a.m. an additional 25%. Overtime exceeding 60 hours in a month attracts a premium of at least 50%.
Small foreign-owned businesses sometimes operate with flexible habits in their early stages: messages at night, occasional weekend work, shifting schedules and an assumption that everyone will simply keep track. That becomes difficult once employees are involved.
Working hours need to be recorded, overtime needs to be authorised and compensated correctly, and managers need to know which communications are genuinely urgent.
The paperwork is relatively manageable when the process is designed early. Reconstructing several months of working-hour records after a dispute is considerably less charming.
Paid Leave Begins Earlier Than Some Employers Expect
A full-time employee who has worked continuously for six months and attended at least 80% of their scheduled working days will generally become entitled to 10 days of annual paid leave. The entitlement increases with continued service, eventually reaching 20 days per year. Proportionate entitlements also apply to qualifying part-time employees.
Employers also have an obligation to ensure that employees who receive at least 10 days of annual paid leave actually take at least five days during the relevant year, taking into account leave already selected by the employee or granted under an organised leave system.
This deserves a place in staffing calculations. A business whose operation depends entirely on one employee being present every weekday has created a fragile staffing structure, regardless of how conscientious that employee happens to be.
Social and Labour Insurance Filings Come With the Hire
Japanese corporations are generally covered workplaces for Employees’ Health Insurance and Employees’ Pension Insurance, and eligible employees must be enrolled. The Japan Pension Service states that coverage applies regardless of nationality, and covered employers generally cannot simply agree with an employee to opt out.
Employment insurance operates under separate rules. Employees who generally work at least 20 prescribed hours per week and are expected to remain employed for at least 31 days fall within its coverage, subject to applicable exclusions.
For ordinary businesses in the 2026 fiscal year, the combined employment insurance rate is 13.5 per 1,000 of wages, of which 8.5 per 1,000 is borne by the employer.
Workers’ compensation insurance also applies broadly when a business employs workers. Its premium is paid by the employer, with rates depending on the type of business.
The agencies involved are different, and so are the forms and deadlines. This is one reason many small companies use a sharoushi, or labour and social security attorney, once they begin hiring.
Hiring Foreign Employees Adds Immigration Checks and Reporting
A Japanese company can employ foreign nationals, provided their status of residence permits the work they will actually perform.
The employer should verify the person’s residence card, status of residence, permitted activities and period of stay before employment begins. Employers also have reporting obligations when covered foreign employees are hired or leave the company.
In most cases this information is reported through Hello Work, with the procedure depending partly on whether the employee is covered by employment insurance.
The number of foreign workers in Japan continues to increase. MHLW reported approximately 2.57 million foreign workers as of October 2025, the highest figure recorded since the reporting system became mandatory, with more than 371,000 workplaces employing foreign staff.
For foreign-owned companies, international recruitment can make obvious sense, particularly where language skills, overseas sales experience or specialised knowledge are required. Visa eligibility still needs to be checked against the actual position. A job title written in English does not determine whether the immigration authorities consider the work appropriate for a particular status of residence.
Probation Is Useful, Within Limits
Probation periods are common in Japan and can give both sides an opportunity to assess whether the role is working properly.
Employers should be careful about treating probation as a period during which employment can be ended freely. JETRO notes that refusing continued employment during or after probation can be treated in a similar manner to dismissal and requires objectively reasonable grounds based on information that emerged during the probationary period.
This makes recruitment and documentation especially important. Job responsibilities should be reasonably specific, expectations should be explained, and genuine performance problems should be recorded and discussed rather than stored silently for a surprise conversation three months later.
Japan’s dismissal rules generally require objectively reasonable grounds and social acceptability. Paying notice or severance does not automatically make a dismissal legally valid.
For a small business, a poor hire can therefore become expensive in several ways. Proper recruitment deserves more attention than filling the seat quickly.
The Ten-Employee Threshold Matters
Once a workplace regularly employs 10 or more workers, the employer is required to prepare formal Rules of Employment and submit them to the relevant Labour Standards Inspection Office. These rules cover matters including working hours, holidays, wages and termination, along with other company policies where applicable.
A company does not need to wait until employee number ten appears before establishing sensible internal rules.
Even a team of three or four benefits from having clear procedures for leave requests, overtime approval, expenses, confidentiality, remote work, equipment, performance reviews and reporting lines. Small teams usually communicate informally, which works beautifully until two people remember the same conversation differently.
Recruitment Should Reflect the Business You Actually Have
Foreign business owners sometimes begin recruitment with a candidate profile copied from the organisation they hope to build in several years.
Early-stage Japanese operations often need something more practical.
A small overseas-owned company may get greater value from an experienced generalist who can communicate with suppliers, coordinate professionals, handle customers and solve routine administrative problems than from a narrowly specialised employee whose role assumes the existence of several departments that have not yet materialised.
Language ability also needs a realistic assessment. An employee may need strong Japanese for government offices, banks, local vendors or customers while also needing enough English to communicate with overseas management. Genuine bilingual business ability can materially affect the available candidate pool and expected salary.
At Nippon Bridge, we generally encourage clients to define the actual work that needs to be performed during the coming 12 months before deciding on the title, seniority or ideal résumé. That tends to produce a more useful job description and a more realistic recruitment budget.
Building the Employment Process
For a first hire, the practical sequence usually includes defining the role and compensation, deciding the employment structure, preparing the employment documents, completing the required insurance registrations and setting up payroll and working-hour records.
Responsibility also needs to be assigned inside the company. Someone must approve leave, deal with payroll questions, review overtime, maintain employment records and communicate with the company’s accountant or labour specialist.
For businesses managed partly from overseas, this deserves particular attention. Japanese employment obligations continue regardless of whether the owner happens to be in Tokyo, Toronto or sitting on a beach with very strong opinions about Slack notifications.
Nippon Bridge supports foreign owners with the practical coordination around company operations in Japan, including connecting the different professional and administrative pieces involved when a company begins building a local team.
Summary
Hiring employees in Japan introduces recurring costs and responsibilities that should be included in the business plan before recruitment starts. Employer insurance contributions commonly add around 15% of wages, and the wider employment budget also needs to cover recruitment, payroll administration, equipment, allowances and professional support.
Employment conditions should be documented clearly, working hours and paid leave need proper systems, qualifying employees require insurance enrollment, and foreign hires bring additional immigration and reporting procedures. Growing companies also encounter further requirements, including formal Rules of Employment once a workplace reaches the ten-worker threshold.
For most small foreign-owned companies, the administrative burden is manageable when the employment structure is set up properly from the beginning. The expensive problems usually emerge from unclear roles, informal working arrangements or compliance tasks that were postponed while everyone was busy running the business.
