January – February
Planning & document lists
Scoping calls for March year-ends, materiality discussions, and circulation of request lists. Ideal time for internal control readiness reviews before the rush.
Engagement calendar
When assurance work lands on the year
A seasonal view of planning kickoffs, inventory observation weeks, and report issuance — so finance teams can reserve capacity before the close compresses.
This calendar is guidance, not a booking engine. Actual dates are confirmed after scoping. March and September remain the busiest months for statutory financial auditing in Japan.
March
Peak fieldwork
Inventory observations, substantive testing, and cut-off work for 31 March reporters. Capacity is limited; deposits may be required to hold observation days.
April – May
Reporting close-out
Clearance of review notes, subsequent events work, and issuance of auditor’s reports ahead of lender and filing deadlines.
June – August
Interim & readiness
Interim testing, first-year opening balance work, and agreed-upon procedures that do not need year-end cut-off evidence.
September
Second peak
Fieldwork for September year-ends and catch-up inventory counts. Travel across western Japan is scheduled earlier in summer.
October – December
Rollover planning
Post-mortem meetings, management letter follow-ups, and calendar holds for the next March cycle. New clients should inquire now for spring capacity.
