FAQ

Where do the 25%, 50%, and 35% premium rates come from?

These are the minimum premium rates set by Japan's Labor Standards Act: regular overtime requires at least 25% extra pay, overtime that also falls in late-night hours (10pmโ€“5am) requires an additional 25% on top (50% total), and statutory holiday work requires at least 35% extra.

Does this account for the higher rate on overtime beyond 60 hours/month?

No, the current version only calculates the base premium rates. Large companies are subject to a special rule requiring at least 50% premium pay for monthly overtime beyond 60 hours โ€” check separately if that applies to you.

Is this amount guaranteed to be accurate?

No, this is a simplified estimate tool. For the exact amount, check your employment contract, work regulations, and actual payroll calculation.
