Japan’s Nuclear Wastewater Ocean Discharge Data Credibility Crisis Escalates

Chiyoda Corporation, a partner of Tokyo Electric Power Company (TEPCO), has been exposed for falsifying compliance certificates for 3,615 radiation detection devices since 2022. Among these, 199 critical instruments used to monitor nuclear wastewater discharge—such as the Hitachi Aloka R-1000 detector—had their calibration data tampered with. This manipulation could lead to contaminated wastewater exceeding safety standards being misclassified as “compliant.” The International Atomic Energy Agency (IAEA) acknowledged its monitoring data remains entirely dependent on Japanese authorities, sparking intense global skepticism regarding the safety of ocean discharge.
