How this service works
Is the Tokyo Stock Exchange (JPX/TSE) open on a date? Returns closed reasons, next/previous trading day and the first/last trading days of the year (daihakkai/dainokai).
Output
Returns a JSON object indicating whether the queried date is a JPX/TSE trading day, the reason for any market closure (holiday name, weekend, etc.), the date of the next trading day, the previous trading day, and the annual first (daihakkai) and last (dainokai) trading days of the year.
Example use cases
Equity settlement date validation
“My trade settles on December 31, 2025 — is the Tokyo Stock Exchange actually open that day, or is it closed? If closed, tell me why and what the next valid JPX trading day is.”
Year-end trading calendar planning
“When is the last trading day of 2025 on the Tokyo Stock Exchange — the dainokai — and when is the first trading day of 2026, the daihakkai?”
Holiday trade scheduling check
“We're planning to execute a large JPX order on November 3, 2025. Is the Tokyo Stock Exchange open that day, or is it a Japanese national holiday?”
Technical details
Endpoint
GEThttps://japan-business-day-api.matchan962.workers.dev/v1/jpx/trading-day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether the Tokyo Stock Exchange (JPX/TSE) specifically is open on a given date, get structured closure reasons, or find adjacent trading days. Prefer this over a generic Japanese business day endpoint when financial market calendars (not just national holidays or bank holidays) are what matter — e.g. for trade settlement, equity operations, or market event scheduling.
Side effects
- Missing or invalid 'date' query parameter returns a 400 error
- Date outside supported range may return an error or empty result
- Non-ISO-8601 date format causes a validation failure
- Payment failure (x402) if USDC balance is insufficient
