Japan's government has issued a warning regarding a phishing scheme involving a fraudulent website that impersonates the official homepage of the Prime Minister's Office. The fake site, which has been confirmed by various sources, claimed to offer 500,000 yen to citizens in exchange for personal information, including names and phone numbers. Authorities have advised the public to exercise caution and verify the authenticity of websites before providing any personal data. The official Prime Minister's Office website can be accessed through its legitimate URL, and individuals are urged to avoid the fake site, which is currently inaccessible.
