The has been a bit of a fuss over Kyoto's Gozan no Okuribi festival which involves burning bonfires on the hillsides around the city. Japan Probe noted that organizers had planned to use firewood from Iwate but received complaints from citizens concerned about radiation. Tests revealed no contamination but the plan was ditched to offset these fears. This then sparked another wave of criticism as the organizers were accused of overreacting and helping to fuel unfounded fears. Consequently, a new order was placed for firewood from Rikuzen Takata in Iwate. Unfortunately, this batch has now been tested and found to have traces of radioactive caesium so organizers have once again decided against using it.
