Overview
- Saitama Prefectural Police, which announced the arrest Tuesday, detained company employee Yusuke Takahashi, 38, on suspicion of copying 26 files that Fujitsu treated as trade secrets and emailing them to his personal account.
- Investigators say the files included customer presentations, sales and negotiation policies, and materials describing logistics services that the parent company managed as confidential business information.
- Takahashi admitted the conduct and told police he took the data to explain his past work during job hunting.
- He left Fujitsu Japan at the end of March 2025 and moved to a logistics firm, where he remains employed, according to police reports.
- Police are examining several personal‑email transfers, reported as four, after Fujitsu raised the issue with authorities in December 2025 and filed a criminal complaint, and no leak of personal customer data has been confirmed.
