When an insured person (excluding an insured person with optional and continued coverage; the same applies in Article 102, paragraph (1)) is unable to engage in labor due to medical treatment, the injury and sickness allowance is paid for the period during which the person is unable to engage in work, starting from the day on which three days elapsed after the day on which the person becomes unable to engage in work.
The amount of injury and sickness allowance per day is an amount equivalent to two-thirds of the amount equivalent to 1/30th of the average standard monthly remuneration amount (limited to the amount specified by the relevant insured person's insurer; the same applies hereinafter in this paragraph) of each month in the most recent 12 consecutive months before the month in which the payment of injury and sickness allowance starts (if the 1/30 amount is a figure with less than five yen in the ones place, it is to be rounded down, and if it is a figure with at least five yen but less than ten yen in the ones place, it is to be rounded up to the nearest ten yen; if the two-thirds amount is a figure with less than 0.5 yen in the ones place, it is rounded down, and if it is a figure with at least 0.5 yen but less than one yen in the ones place, it is to be rounded up to the nearest one yen); provided, however, that if the number of consecutive months for which the average standard monthly remuneration amount is determined is less than 12, an amount equivalent to two-thirds of an amount equivalent to smaller of the amounts listed in the following items (if the amount is a figure with less than 0.5 yen in the one place, it is to be rounded down, and if it is a figure with at least 0.5 yen but less than one yen in the ones place, it is to be rounded up to the nearest one yen).
傷病手当金の額は、一日につき、傷病手当金の支給を始める日の属する月以前の直近の継続した十二月間の各月の標準報酬月額（被保険者が現に属する保険者等により定められたものに限る。以下この項において同じ。）を平均した額の三十分の一に相当する額（その額に、五円未満の端数があるときは、これを切り捨て、五円以上十円未満の端数があるときは、これを十円に切り上げるものとする。）の三分の二に相当する金額（その金額に、五十銭未満の端数があるときは、これを切り捨て、五十銭以上一円未満の端数があるときは、これを一円に切り上げるものとする。）とする。ただし、同日の属する月以前の直近の継続した期間において標準報酬月額が定められている月が十二月に満たない場合にあっては、次の各号に掲げる額のうちいずれか少ない額の三分の二に相当する金額（その金額に、五十銭未満の端数があるときは、これを切り捨て、五十銭以上一円未満の端数があるときは、これを一円に切り上げるものとする。）とする。
an amount equivalent to 1/30th of the average standard monthly remuneration amount for each consecutive month before the month which includes the day on which the payment of injury and sickness allowance starts (if the amount is a figure with less than five, it is to be rounded down, and if it is a figure with at least five yen but less than ten yen, it is to be rounded up to the nearest ten yen); or
傷病手当金の支給を始める日の属する月以前の直近の継続した各月の標準報酬月額を平均した額の三十分の一に相当する額（その額に、五円未満の端数があるときは、これを切り捨て、五円以上十円未満の端数があるときは、これを十円に切り上げるものとする。）
an amount equivalent to 1/30th of the standard monthly remuneration amount calculated when the average standard monthly remuneration amount of all insured persons on September 30 in the year preceding the fiscal year which includes the day on which payment of injury and sickness allowance starts is deemed as the monthly remuneration amount which is the basis of the standard monthly amount remuneration (if the amount is a figure with less than five yen, it is to be rounded down, and if it is a figure with at least five yen but less than ten yen, it is to be rounded up to the nearest 10 yen).
傷病手当金の支給を始める日の属する年度の前年度の九月三十日における全被保険者の同月の標準報酬月額を平均した額を標準報酬月額の基礎となる報酬月額とみなしたときの標準報酬月額の三十分の一に相当する額（その額に、五円未満の端数があるときは、これを切り捨て、五円以上十円未満の端数があるときは、これを十円に切り上げるものとする。）
Beyond what is provided for in the preceding paragraph, necessary matters concerning calculation of the amount of injury and sickness allowance are specified by Order of the Ministry of Health, Labour, and Welfare.
