Factual republishing of public filings — not investment advice, and not a registered investment adviser in any jurisdiction. Summaries are AI-generated; the original Japanese filing prevails.

What you get

Large-shareholding (5%) reports

Who crossed 5%, the holding ratio, the stated purpose, and whether a material proposal was flagged — translated from the original filing.

Activist name-matching

We resolve fund vehicles to the groups behind them (e.g. the Murakami group's many entities), so you see the signal, not the noise.

Watchlist alerts

Pick the tickers and investors you follow; get an email the moment a matching filing lands. A mechanical filter on the same factual feed — no commentary added.

How it works

We poll EDINET (the FSA's official disclosure system) on every Japanese business day, extract the facts from each filing, cross-check the figures against the source, and translate them into a short English summary. Every item links back to the original filing on EDINET, and we never alter or add to the facts.
