The Asahi Shimbun has recently obtained a copy of the transcripts of testimony given before a government investigation panel by Masao Yoshida, who served as general manager of the Fukushima No. 1 nuclear power plant when it succumbed to a Level 7 disaster, the highest on the International Nuclear Events Scale, following the Great East Japan Earthquake and tsunami of March 11, 2011.

The document remains the only available official transcript of the testimony by Yoshida, the on-site commander of efforts to bring the situation under control, who died in July 2013 without having disclosed much to media organizations about the accident at the plant, operated by Tokyo Electric Power Co.

The transcript, not to be released publicly at Yoshida’s request, was gathering dust in government offices.
