What this tool returns

Returns holders of more than 5% as listed from large-shareholding reports in the latest annual securities report, one row per holder, with a link to the source on EDINET. Rows are sorted by holding ratio, largest first. When the annual report lists a group as one total row ("... and N joint holders"), it is returned as one row; for each joint holder see /stable/large-holding-reports. Figures stated in thousands of shares are converted to shares. The holding ratio is a 0–1 decimal (0.0774 = 7.74%).
