A large credential dump (20+ GB) containing email:password pairs predominantly from Japanese email domains including yahoo.co.jp, docomo.ne.jp, ezweb.ne.jp, softbank.ne.jp, and various Japanese ISP and corporate domains. The file is named 'urluserpass' suggesting it may be a URL:user:pass or user:pass combo list. No single source breach is identifiable; this appears to be a compilation or combo list targeting Japanese internet users.
