In Japan, a significant data breach has been reported involving NTT Communications. Between February 2025, an unauthorized access incident may have compromised the information of approximately 17,891 corporate clients, including sensitive details such as phone numbers and addresses. This breach follows a separate incident in Tokushima Prefecture, where an unidentified third party exploited the Board of Education's email server, sending around 1.4 million spam emails and 137 million messages to non-existent addresses. The implications of these breaches raise concerns about cybersecurity and data protection in the region.
