How this service works
Japanese equities dividend/shareholder-benefit schedule: from a record date (kenri kakutei-bi) returns the last cum-rights trading day and the ex-rights date under T+2 settlement, handling weekends and holidays.
Output
Returns the ex-rights date (the first trading day on which buying the stock no longer confers rights) and the last cum-rights trading day (the final day a buyer is entitled to the dividend/benefit), both computed under Japanese T+2 settlement rules with JPX weekends and national holidays excluded.
Example use cases
Dividend capture strategy planning
“I want to buy a Japanese stock to capture the dividend — the record date is 2025-09-30. What's the last day I can buy shares on the Tokyo Stock Exchange and still be eligible, and when does it go ex-dividend?”
Shareholder benefit eligibility check
“A Japanese company offers shareholder benefits with a kenri kakutei-bi of 2025-06-30. Can you tell me the ex-rights date and the final cum-rights trading day under T+2 settlement so I know the deadline to buy?”
Automated portfolio event calendar
“I'm building a calendar of Japanese equity corporate actions. For the record date 2025-12-31, calculate the ex-dividend date and last cum-rights day on JPX so I can add it to the schedule.”

Choose this endpoint when you need to compute Japanese equity ex-rights and cum-rights dates from a shareholder record date, specifically under JPX T+2 settlement with accurate holiday handling. It is purpose-built for Japanese equities dividend and shareholder-benefit scheduling, outperforming generic business-day calculators that lack JPX holiday calendars or T+2 settlement logic.
