When I started my research project on Fukushima nuclear disaster back in 2013, I knew that a documentary film was something I would like to produce. But I had no idea then what the focus of the documentary film would be. In mid-201 5, Ryuma Shineha, a colleague at Seijo University, introduced me to Dr. Arifumi Hasegawa via email. I was doing fieldwork in Fukushima when I received an email from Ryuma that Dr. Hasegawa would like to meet me. The next morning I was on a train that brought me from Fukushima station to Kanayagawa station, where Hasegawa came to pick me up, still wearing a doctor suit. He took me to his office at Fukushima Medical University's Radiation Emergency Medical Center. During one hour of conversation, Hasegawa told me his story of how he built the facility as a response to radiation hazard in the aftermath of the nuclear meltdown at Fukushima Daiichi. A deep impression of what Hasegawa experienced during and after the nuclear crisis drew me into thinking of making a documentary film about his story. Two months later I emailed Hasegawa asking whether he would be interested in collaborating with me on a documentary film project focusing on radiation emergency medicine in Fukushima. Before long, he responded with a yes, and the rest is history.
