General AI still answers 67% (the top-up postdates most training data) and garbles the condition’s asymmetry: the father’s +13% is satisfied automatically while the employed mother is on 産後休業 — it is the mother’s claim that needs the father to take ≥14 days (or a waiver). Uses the caps valid 1 Aug 2025 – 31 Jul 2026 (¥16,110 daily ceiling; ¥58,640 top-up cap per 28 days); every cap revises each 1 August.","inputSchema":{"type":"object","properties":{"claimant":{"description":"Who is claiming? The asymmetry general AI misses: a father’s +13% condition is satisfied AUTOMATICALLY while the employed mother is on maternity leave (産後休業 counts as waiver #6) — he only needs his own ≥14 days. The MOTHER’s claim is the one that needs the father to take ≥14 days of leave, unless a waiver applies (spouse not employed / self-employed / single parent).","type":"string","enum":["father","mother"],"default":"father"},"monthlyWage":{"description":"Average monthly wage before leave (¥/mo) Average of the 6 months of wages before the leave starts — this sets your 賃金日額 (daily wage) = wage × 6 ÷ 180 = wage ÷ 30. Use gross pay including fixed allowances, before tax and social insurance.","type":"number","minimum":0,"default":350000},"leaveDays":{"description":"Leave days to model (days) Total benefit days you plan to take. The 67% rate runs for the first 180 benefit days (the counter includes 産後パパ育休 days), then steps down to 50%.","type":"number","minimum":5,"maximum":365,"default":180},"bothCondition":{"description":"Is the +13% condition met? The 出生後休業支援給付金 needs your own leave of ≥14 days within the statutory window AND the spouse condition per the claimant note above (a father’s is auto-met while the employed mother is on 産後休業; a mother’s needs the father’s ≥14 days or a waiver). When met, the first 28 days pay 80% gross.","type":"string","enum":["yes","no"],"default":"yes"}},"required":[],"additionalProperties":false},"methodology":["Daily wage (賃金日額): total wages of the 6 months before leave ÷ 180 — equivalently, average monthly wage ÷ 30. Clamped to the ¥3,014 floor and ¥16,110 ceiling valid 1 Aug 2025 – 31 Jul 2026 (the prior window’s ceiling was ¥15,690 — a stale figure still widely quoted). These bounds revise every 1 August from the 毎月勤労統計 wage statistics.","Base benefit (育児休業給付金): 67% of the daily wage for the first 180 benefit days, 50% from day 181. The published monthly caps — ¥323,811 at 67% and ¥241,650 at 50% for a 30-day month — equal 67%/50% of the ¥483,300 monthly wage ceiling, so the daily-cap model here implies them exactly. The 180-day counter includes 出生時育児休業 (産後パパ育休) benefit days already taken.","Top-up (出生後休業支援給付金, from 1 April 2025): +13 percentage points on up to 28 days of qualifying leave — lifting those days to 80% gross. Modeled as min(13% × capped daily wage × min(days, 28), ¥58,640 × min(days, 28) ÷ 28). Conditions: the claimant’s own leave of ≥14 days within the statutory window, AND the spouse also taking ≥14 days — with waivers including: the spouse is on 産後休業 (which is why an employed mother’s maternity leave auto-satisfies the father’s claim), the spouse is not an employee (self-employed / not working), or the claimant is a single parent. The published per-28-day floor of ¥10,970 is implied by the ¥3,014 daily-wage floor (13% × ¥3,014 × 28 ≈ ¥10,971) and never binds separately in this model.","Eligibility (not computed here): covered by 雇用保険 (employment insurance) with 12 months having ≥11 wage-basis days (or ≥80 wage-basis hours) in the 2 years before leave starts. Fixed-term workers need the contract not to end within the child’s first 18 months. ハローワーク determines eligibility from the employer’s filings.","Tax and social insurance: the benefits are not taxable income, and health/pension premiums are exempted for months where the leave spans the month-end or covers ≥14 days of the starting month — which is why 80% of gross approximates 100% of normal net take-home. The “≈% of net” line in the results assumes a flat ~20% combined tax + social-insurance wedge on normal pay and is labeled illustrative; the real wedge varies with income and municipality.","Wages during leave: employer pay up to 13% of the 賃金月額 leaves the base benefit whole; pay between 13% and 80% reduces the benefit so pay + benefit ≤ 80%; pay at 80% or more zeroes the base benefit. The +13% top-up is not reduced by employer pay. During 産後パパ育休, agreed partial work is limited to 80 hours / 10 days per 28-day leave.","Rounding: this tool keeps exact formula values (no per-payment yen rounding). Hello Work rounds the daily wage and each payment to the yen, so official figures can differ from these by a few yen — e.g. the published 28-day 出生時 base maximum ¥302,223 versus the exact 0.67 × ¥16,110 × 28 = ¥302,223.6 here.","A related benefit not computed here: 育児時短就業給付金 (also from April 2025) pays 10% of wages when working shortened hours while raising a child under 2 — see the FAQ."],"usage":"POST https://xearno.tools/api/v1/tools/japan-childcare-leave-benefit with a JSON body matching inputSchema."}
