Overview
- On December 14, researchers from Fukushima Medical University and Chiba University conducted a winter indoor‑evacuation experiment at a Kashiwazaki City community center designated as a radiation protection facility near TEPCO’s Kashiwazaki‑Kariwa plant.
- The team ran positive‑pressure systems and assessed methods for sealing broken windows to limit radioactive infiltration, with results intended to inform real‑world facility operations.
- Sapporo Fire Department disclosed it misdirected an ambulance, delaying arrival by about three minutes; an elderly woman in cardiac arrest later died, and officials say any causal link is unclear.
- A newly issued Hokkaido–Sanriku aftershock advisory’s weeklong preparedness push surfaced challenges including evacuation congestion and cold‑weather countermeasures.
- Sapporo prosecutors decided on December 11 not to indict two Hanai‑gumi executives who were sent on suspicion of assault causing serious injury, citing the state of the evidence.
