Scope of HibiCalc

HibiCalc provides independent Japanese-focused calculators based on public rules and documents. It does not replace government agencies, financial institutions, licensed tax professionals, or official benefit offices.

All outputs are estimates.

Why actual results may differ

• Changes in laws, rates, premium percentages, benefit rules, and fares.
• Different rounding and condition handling by municipalities, institutions, employers, or operators.
• Missing allowances, caps, special regimes, or individual contract terms.
• Covered calculator scope may not include your exact legal or benefit path.
• Inputs marked as excluded, approximate, or not covered may not reflect your case.

Use for official decisions

1. Confirm the latest notices from the relevant authority.
2. Verify applicability period, conditions, and rounding rules.
3. Consult a qualified professional when necessary.
4. Use HibiCalc as a preparation aid only.
