Contact

Big Investor Watch accepts messages through direct messages or replies to its official X account, @kujira_watch. The operator does not publish a name or email address, so this is the only contact point. Messages in English or Japanese are both fine.

Reporting an error

If you find a wrong number, company name, or holding ratio in an article, send the article URL. We check it against the original filing (EDINET large-shareholding reports, TDnet timely disclosures) and correct or remove the article if the error is confirmed. The English edition follows the Japanese edition; when the two disagree, the Japanese edition carries the latest corrected data.

Correction and removal requests

Companies and investors named in an article can request a correction or removal through the same channel. The site only covers information disclosed under Japan's Financial Instruments and Exchange Act, but please tell us if an article misstates a filing or describes it in a way the filing does not support.

Citation, reuse, and media inquiries

Requests to quote or reuse articles and charts, and media inquiries, go to the same contact point. The conditions for quoting are set out in the Terms of Use.

What we cannot answer

This site is not a registered investment adviser. We cannot answer questions about whether to buy or sell a particular stock, and we do not accept requests to feature a stock or to publish content that is not based on a filing.

Personal information

The site has no contact form and does not collect names or email addresses on its pages. Messages sent through X are used only to respond to the request. See the Privacy Policy for details.
