Magnitude of Fukushima tsunami had a 1923 Kanto earthquake/tsunami
precedent which was ignored by TEPCO and the Japanese government
In the aftermath of the Fukushima earthquake/tsunami, plant operator TEPCO and the Japanese government have claimed that the Fukushima nuclear reactor plants were designed to meet the largest expected tsunami wave. This is quite simply not true. The 7.9 magnitude 1923 Kanto earthquake produced a well-documented 40 foot tsunami. See the recent Smithsonian magazine article.

The lessons of the 1995 Kobe earthquake were not learned: see Japan Policy Research Institute paper.
