Fukushima Daiichi Nuclear Power Plant
Pendleton has a sister city relationship with Minamisōma, in Fukushima Prefecture, Japan. Minamisoma is north of the Fukushima Daiichi Nuclear Power Plant, which was damaged by the 2011 Tōhoku earthquake and tsunami. Since then, Japanese exchange students from Minamisoma have continued to visit Pendleton, though students from Pendleton have stopped visiting Minamisoma over growing radiation concerns.
