When a company employee in Kyōkai Kenpo takes 4 or more consecutive days off work due to an illness or injury not related to work and receives no salary during that time, this program pays, from the 4th day off, "average standard monthly remuneration ÷ 30 × 2/3" per day.

Severe morning sickness during pregnancy (hyperemesis gravidarum), threatened miscarriage, threatened preterm labor and similar conditions are covered by the Sickness and Injury Allowance when a doctor confirms that "time off is needed for treatment." Even if morning sickness itself is not treated as an illness, it is covered if you are diagnosed with dehydration or hyperemesis gravidarum. Periods of rest at home ordered by a doctor are also covered.

The maximum payment period is a total of 1 year and 6 months from the payment start date (from January 2022). The first 3 consecutive days are a "waiting period" (no payment), and payment starts on the 4th day. The waiting period includes weekends and paid leave.

If the payment period overlaps with the Maternity Allowance (42 days before to 56 days after birth), as a rule the Maternity Allowance is paid first, and the Sickness and Injury Allowance is suspended or adjusted for the difference.

Only the Kyōkai Kenpo insured person is covered (dependent family members and self-employed National Health Insurance members are not). The standard monthly remuneration is calculated the same way as for the Maternity Allowance.

The amount above is a guide for "when you are off work for consecutive days and receive no salary." No allowance is paid for days when you receive salary, but if the salary is less than the Sickness and Injury Allowance, the difference is paid. For periods that overlap with the Maternity Allowance, the Maternity Allowance is paid, and the difference is paid only if the Sickness and Injury Allowance would be larger. For details, ask the prefectural branch of the Japan Health Insurance Association (Kyōkai Kenpo) you belong to.
