Last August, much consternation was caused when an apparent rogue worker at the Fukushima No. 1 nuclear power plant appeared on a live-to-air webcam and pointed an accusatory finger directly at the camera. After about 20 minutes, the man, who was clad in a full-body radiation suit that masked his identity, promptly disappeared.

Who was he? What was he trying to say, and to whom? When the story was picked up in the media, even Cabinet Office Parliamentary Secretary Yasuhiro Sonoda was drawn into the debate. "I would like him to tell us what his intentions were," he said at a press conference on Sept. 8.

Now some light is about to be thrown on the episode — or perhaps more darkness. Tokyo-based artist Kota Takeuchi has announced he will include the video, which is now available for all to see on YouTube, in a solo exhibition he will hold from March 17 at XYZ collective in Tokyo's Setagaya Ward.
