Japan reporting cycles and business-day rules
Japanese business-day cycles align with gensen choshu zei (withholding tax) on the 10th, shakai hoken hi (social insurance) by the end of the month, and quarterly hojin zei (corporate tax) instalments. The Zengin Data Telecommunication System clears domestic transfers same-day; the Bank of Japan operates BOJ-NET as the wholesale RTGS system. JFY (Japanese fiscal year) runs April to March for most listed companies and the government, so quarter-end cycles do not align with calendar quarters. Half-year shoyo (bonus) payments cluster mid-June and mid-December.

Using this calculator in Japan
A Tokyo-listed manufacturer's keiri-bu uses the 21-day May 2029 count to align gensen choshu zei (withholding tax) remittance on the 10th with Zengin-system clearing windows and Bank of Japan settlement. A Yokohama trading company uses the count to track JFY (April to March) quarter-end accrual cycles.
