Who is buying Japanese stocks? Large-shareholding filings, explained in English

Investors who cross 5% of a listed Japanese company must file a large-shareholding report with EDINET, the Financial Services Agency's disclosure system. This site reads those filings daily and explains who bought or sold what, in plain English. The English edition covers a subset of articles; the Japanese edition carries every disclosure, plus stock and investor pages.
