Reaching “one quarter” is a psychological marker, but the hardest technical and political hurdles lie ahead. Full decommissioning is not expected until .

Led by Tetsuo Ishikawa and a team from Fukushima Medical University, the study's methodology was rigorous. Researchers randomly selected 5,350 subjects from seven distinct regions across Fukushima Prefecture and then conducted a door-to-door survey of non-respondents to collect their information. The statistical results were clear and carry profound implications for ongoing health monitoring:

One quarter Fukushima, upd.

The vast fields of steel storage tanks that once dominated the Fukushima landscape are officially beginning to disappear.

Reports from early 2026 confirm that the radioactive concentration of the discharged water is significantly below international and operational targets.

All damaged reactors are maintained in a stable, cold state with consistent cooling systems.

The discharge of Treated Radioactive Water (ALPS-treated water) into the sea began in 2023, and it remains a heavily monitored part of the operation.

The timeline for total decommissioning is estimated to be 30 to 40 years (ending roughly between 2041 and 2051). The next phases include:

One of the most controversial aspects of the Fukushima recovery is the release of treated radioactive water into the Pacific Ocean. This process has been ongoing since August 2023 and continues in defined quarterly rounds.
