Japan — April 2026

Japan businesses have 21 working days in April 2026 — that's 30 calendar days minus 8 weekend days and 1 weekday public holiday (Shōwa Day). Northern-hemisphere spring and Southern-hemisphere autumn typically governs the work-rhythm in April; project deadlines and payroll cycles in Japan should account for the holiday days listed above. April typically holds the Easter long weekend in Western Christianity and several South-and-Southeast-Asian new-year celebrations including Songkran and Vaisakhi. For pay-period planning, April 2026 contains 4 full work-weeks plus 1 additional weekday, useful when scheduling milestones or quarterly reviews. The working-day count above counts substitute days as a single deduction — it does not double-count when a public holiday falling on a weekend is moved to a Monday or Friday. Use this figure as the authoritative baseline for Japan payroll-period calculations.
