In brief
Japan’s Foreign Ministry announced a suspected leak of personal information through an external network amid an ongoing investigation. Facebook reports from a Yomiuri Shimbun page suggest 13,000 website submissions could have been exposed via unauthorized cloud access, and Kyodo News notes the government is attempting to block a website believed to hold stolen data.
Japan’s Foreign Ministry announced on October 30, 2026 that it suspects a leak of personal data originating from an external network, officials said, as an investigation has begun. Authorities expect to issue further details once the source is identified.
Kyodo News reported that the ministry’s suspicion follows a pattern of recent data breaches across the country and that the investigation will involve identifying the external network responsible for the alleged export of Japan citizens’ sensitive information.
In a separate but related development, a Facebook post from The Japan News by The Yomiuri Shimbun claimed that around 13,000 website submissions may have been exposed following unauthorized access to a cloud service. The post, noted by tech observers, suggests that the data leak could involve personal identification details, though the claim is currently unverified by any official body.
Kyodo also noted that the Japanese government has sought to ask telecommunications operators to block access to a website that was purported to publish stolen customer data. This directive comes as part of broader efforts to mitigate further exposure of personal information.
Stakeholders have urged transparency throughout the probe, with the ministry promising to share more concrete findings once the responsible network or entity is confirmed. In the meantime, users are advised to remain cautious about sharing personal data online and to stay updated with official statements.
