Cost to Hire in Japan 2026: Social Insurance and Bonus Costs

About ¥8,099,000 a year. On top of the ¥7,000,000 salary you pay roughly ¥352,800 of health insurance, ¥640,500 of pension, ¥59,500 of employment insurance, ¥21,000 of rousai (workers' accident) insurance at an office rate, and ¥25,200 of the child and childcare levy. That is 15.7% on top of base pay for an employee under 40, before any bonus, equipment or recruitment cost.

Because two of the five lines stop growing. Pension contributions are calculated on standard monthly remuneration capped at ¥650,000, so the employer's pension bill stops rising once salary passes about ¥7,800,000 a year. Health insurance has its own, much higher cap at ¥1,390,000 a month. The result is that the employer add-on falls from 15.7% at ¥7,000,000 to about 9.1% at ¥20,000,000. A senior hire costs proportionally less to employ than a mid-level one, which is the opposite of how most people assume payroll scales.

No, and budgeting as if they do is the most common mistake. Bonuses attract health and pension contributions in the same way monthly salary does, which is why a bonus-heavy package does not reduce the employer's contribution bill. On a ¥7,000,000 salary with a 20% bonus, the package is ¥8,400,000 and the full-year employer cost is about ¥9,652,080. Statutory ceilings apply to bonus contributions separately from monthly pay, so very large single bonuses are treated slightly differently from the annualised view this calculator takes.

Nursing care insurance (介護保険) switches on at 40 and off at 65. It is another 1:1 match at 0.81% each side on the same base as health insurance. At ¥7,000,000 that is ¥56,700 more for the employer, taking the add-on from 15.7% to 16.5%. It is worth modelling when your candidate shortlist spans that birthday, though it is never a reason to prefer one candidate over another.

Health insurance does vary. Kyokai Kenpo sets its health insurance rate prefecture by prefecture, and the figures here use the Tokyo rate of 4.925% for each side, plus 0.115% each for the child and childcare support levy (子ども・子育て支援金) collected with it since March 2026. Other prefectures sit a little either side of that, so a Fukuoka or Hokkaido payroll will not match a Tokyo one to the yen. Pension, employment insurance and the childcare levy are national and do not move with location.

Rousai hoken is industry-rated, not one national number, and the employer pays all of it. Office and software work sits at the bottom of the scale, around 0.25% to 0.3%, which is what these figures assume. Construction, transport and heavy industry run far higher, up to 8.8%. If you are budgeting for a non-office role, change that input before trusting the total.

On statutory employer contributions alone, Japan sits in the middle and looks cheap at senior levels. Comparing like for like, Japan adds about 15.7% at ¥7,000,000, against roughly 6.2% in the Philippines, 23.5% in Vietnam, 24.8% in Mexico, 31.4% in Sweden and 34.8% in Brazil. Japan's ceilings mean that gap widens in Japan's favour the more senior the hire.

Commuting allowance (通勤手当), which most Japanese employers pay and which is customary rather than statutory, along with equipment, recruitment fees, any retirement allowance provision and management time. The calculator has inputs for equipment and recruitment so you can add them deliberately rather than hiding them inside a single multiplier.
