The Tokyo District Court was the 24th trial of TEPCO's former management team, which was forcibly charged with negligence resulting in death and injury in charge of TEPCO Fukushima Daiichi Nuclear Power Plant incident. The former chairman of the company president Katsumata Tsunyu (78) and others in 2008 announced that the former executive of Toden stated that it was postponed while acknowledging the policy of implementing the tsunami countermeasure based on the earthquake prediction by the specialized agency of the country at the same nuclear power plant The record was adopted evidence and the whole sentence was read aloud in court.

A designated attorney for the prosecutor's office argues that "defendants postponed while recognizing the necessity of tsunami countermeasures," and this record is consistent with this. Meanwhile, the defense side is fighting as "The earthquake prediction of the country is not reliable, the policy of measures was not decided".

What was adopted was a record that Mr. Kazuhiko Yamashita, who was the director of the earthquake countermeasure director responsible for earthquake resistance measures of nuclear power plant, wrote to the prosecutor about 12 to 14 years. Originally Mr. Yamashita's witness examination was scheduled to be held, but the presiding judge adopted the record as Kenichi Nagabuchi "as not being able to testify in court."

According to a read aloud document, TEPCO initially assumed that a tsunami of more than 7, 7 meters will flow over the Fukushima Daiichi nuclear power plant with a simple calculation based on the "long-term evaluation" published by the specialized agency of the country in 2002. Mr. Yamashita showed tsunami countermeasures considering long-term evaluation in February 2008 when Mr. Katsumata and his colleagues attended the meeting, they said that they were accepted without being opposed and were also accepted at the executive meeting in March of the same year.

However, when a subsidiary of TEPCO conducted detailed calculations based on the long-term evaluation, the possibility that the tsunami height could reach 15 · 7 meters, exceeding the height of the site (10 m) where the main facilities of the nuclear power plant existed It turned out to be. In July of the same year, this number was reported to TEPCO and others, and Mr. Makoto Makoto (68) who was deputy director of nuclear power and location in July of the same year ordered to postpone tsunami measures based on long-term evaluation.

According to the record, TEPCO's executives and others acknowledged the reason for the policy change "large-scale countermeasure work is necessary, there is a possibility that explanation to the country and localities will be lost, and there is a possibility that the nuclear power plant will be forced to stop" It is said. Mr. Yamashita also stated that "If the assumed tsunami height is less than 10 meters, it would have taken immediate measures based on the national earthquake prediction."

Yuichi Kaiichi, an attorney of residents who filed criminal complaints against the former management team of TEPCO, said at a post-trial interview "The executives were surprised that the executives mentioned the internal situation of TEPCO so far, The abnormality that it does not do it was clear.
