Editorial interest 82/100 Selection signal · not a rating of the site

An independent research site tracks Japanese shareholder activism, proposals, buybacks, and take-privates from EDINET and TDnet filings.

Landing page captured for the 2026-08-31 issue.

Field notes

The site organizes corporate-change reporting around primary EDINET and TDnet filings, then supplies English records with company names, ownership figures, vote percentages, and transaction details. Visible examples include Oasis Management's 7.48% IIJ stake, Bain Capital's ¥155.7bn MCJ take-private, and a 54.70% poison-pill vote at Toho HD. Quorum also directs readers to a Substack for weekly filings and labels the material independent research rather than investment advice.
