3. The Data may contain errors, delays, omissions, or interpretive differences due to API responses at the time of retrieval, the Operator's aggregation logic, FX retrieval timing, approximations of social-insurance rates (Tokyo Kyokai Kenpo basis, etc.), fallback for cells with small sample sizes, accuracy limitations of quantile estimation, splice points between Reiwa-era and pre-Reiwa-era tables, and similar factors.
4. The Operator makes no warranty, express or implied, as to the accuracy, completeness, timeliness, usefulness, fitness for a particular purpose, or consistency with official statistics of the Data.
5. When using the Data, the User shall consult the primary sources of public institutions (the e-Stat official site, MHLW's published wage census materials, OECD official statistics, etc.) as necessary.

Article 8 (Disclaimer regarding calculation results, estimated percentiles, and estimated income)

1. The estimated annual income, age-based earnings curves, gender pay gap, industry/occupation/prefecture/visa-type aggregations, percentile rankings, total cost of employment including social insurance, cost-of-living coverage, purchasing-power comparison, real-wage trends, international comparisons, and any other calculation results provided by the Service (the "Results") are reference values, approximations, or estimates computed by the Operator's own algorithms, and do not guarantee the User's actual income, living standard, market value in recruitment, employer cost burden, or migration economics.
2. Percentile rankings are estimated by the Operator from published average values and published quantiles of the Basic Survey on Wage Structure, and may differ from the actual income distribution. Pay particular attention where the Service marks values as "estimated".
3. The Results do not take into account the situation of any specific individual, household, company, or business, and are merely statistical or reference numbers based on typical assumptions.
4. The User shall not rely on the Results as the basis for any decision, including career change, job search, entrepreneurship, hiring, salary negotiation, employment contracts, migration, visa application, taxation, payroll budgeting, investment, education, or remittance. When making such decisions, the User shall consult certified social insurance labor consultants, tax accountants, lawyers, administrative scriveners, recruitment agents, Hello Work, or other qualified professionals or public institutions.
5. The Operator bears no responsibility for any consequences (including economic loss, lost opportunity, emotional distress, litigation, administrative dispositions, and similar) arising from the User's reliance on the Results.
