A series of emails threatening to plant explosives at major courthouses nationwide caused a stir, prompting the deployment of special police forces and military authorities. The emails were purportedly sent by someone claiming to be a member of a Japanese idol group, who lamented the pain suffered due to contract termination and malicious comments, demanding justice through terrorism. Thankfully, no actual explosives were found, but some courthouses experienced confusion, including staff evacuations and access restrictions. Police suspect that the email sender has been repeatedly sending false terrorism threat emails from Japan since 2023 and have launched an investigation.
