Today marks the anniversary of Japan’s worst catastrophe since 1945. In 2011 the most powerful earthquake ever measured in the country begat a tsunami that washed away entire towns and villages in the north-east. Three reactors at the Fukushima Dai-ichi nuclear-power station melted down. Over 18,000 were lost in the quake and tsunami; 150,000 were displaced. The nuclear clean-up is ill-planned, and still in its early stages. Decommissioning is only 10% complete; four decades of perilous and complex tasks lie ahead, including the removal of melted fuel. Around 59,000 people are still in temporary housing. Some think Shinzo Abe’s government would rather not dwell on the disaster as it tries to reactivate nuclear plants. Energy costs soared after Fukushima. Yet earlier this week a court unexpectedly ordered the shutdown on safety grounds of two recently restarted reactors 350km (215 miles) west of Tokyo. The five-year-old wounds are far from healed.
