# JPX API: Japan Exchange Group market data

Jun 16, 2026 · 2 min read

Japan's equity markets — the Tokyo Stock Exchange and Osaka Exchange, collectively the Japan Exchange Group (JPX) — are the world's third-largest by market capitalisation. Until now, accessing structured JPX market data meant paying for a data-vendor subscription or scraping the official JPX website, which publishes its statistics as HTML tables and PDF downloads. The JPX API changes that.

Today we're launching the [JPX API](https://anysite.io/endpoints/jpx/) — 13 dedicated endpoints covering Japan's equity markets, accessible through the same Anysite API and credit-based pricing as every other endpoint in the catalog.

## What the JPX API covers

The endpoints are organised into four families:

JPX endpoints by family At launch: 13 endpoints. Equities cover more than half of them.

| Item | Endpoints |
| --- | --- |
| Equities | 7 |
| Listings | 4 |
| Indices | 1 |
| Statistics | 1 |

### Equities (7 endpoints)

The equities family covers the day-to-day data institutional and quantitative traders need: upcoming ex-dividend events, ex-rights and ex-dividend detachments from the most recent trading day, securities under current trading suspension, weekly and monthly index return data, margin trading outstanding balances, segment-level market statistics (Prime, Standard, Growth), and top stocks by turnover — the day's most active names by segment.

### Indices (1 endpoint)

Current price data for JPX market indices: TOPIX, Nikkei 225, and the segment sub-indices. Index name, current level, change, and percentage change — in one call.

### Listings (4 endpoints)

The listings family covers the universe of what's listed: TOPIX constituent stocks with their TSE 33-sector classification and component weights (the foundation of any Japan index-replication or factor model), monthly investment trust and ETF quotation listings, REIT trading statistics, and listed company counts by market segment.

### Statistics (1 endpoint)

Weekly investor-type trading statistics: the breakdown of buy and sell volumes by investor category — foreign investors, domestic institutions, retail investors, and proprietary trading desks. This is the most-watched weekly data release for anyone following Japan equity market flows. It distinguishes whether a Japan rally is foreign-driven or domestically-led — a distinction that matters for macro positioning.

## What you can build

A few concrete use cases:

**Market monitoring dashboards.** Pull index levels, top movers by turnover, and segment stats in three calls at market open. Build the Japan equity dashboard you couldn't afford before.

**Corporate actions pipelines.** Check upcoming ex-dividend dates and same-day rights detachments programmatically — a feed that event-driven strategies, portfolio managers, and compliance teams all need, and that previously required a dedicated data vendor.

**Index replication and factor models.** The TOPIX constituents endpoint returns the full list of constituent stocks with sector weights. Combine it with the margin balance and investor-type data for a quantitative signal stack covering Japan.

**ETF and REIT screening.** The full JPX ETF and REIT listing universe — fund name, ticker, NAV, market metrics — available as JSON for the first time.

## JPX API pricing and access

All 13 JPX endpoints cost 1 credit per request. The Starter plan at $49/mo includes 15,000 credits, which is more than enough for comprehensive daily JPX coverage.
