What it does
This actor delivers the daily FSA-mandated short-selling balance disclosures published by the Japan Exchange Group (JPX), which cover every reported short position of 0.5% or more. Each record gives the ticker, company name in Japanese and English, the short holder, the position size, the percentage of shares outstanding, and the report date — the raw material for tracking institutional short positioning on Japanese equities.

FAQ
What is the reporting threshold?
Japan's FSA mandates disclosure of short positions of 0.5% or more of shares outstanding, so the dataset captures every position at or above that level.
How fresh is the data?
Balances are published daily by JPX, and each record carries its own report date so you can build a time series of how a position evolves.
Are company names available in English?
Yes — each record includes both the Japanese and English issuer name alongside the JPX ticker.
