Shinji Higuchi of Shin Godzilla fame did a tokusatsu version called Sinking of Japan in 2006, starring Tsuyoshi Kusanagi and Kou Shibasaki.
The anime is based on the best-selling 1973 disaster novel of the same name in which strong earthquakes cause Japan to sink into the ocean.
This anime version, brought to life by Yuasa’s Studio Saru, looks incredibly promising.
In 1973, a movie version called Tidal Wave was released in Japan, and Roger Corman bought the film rights, edited it heavily, and add new scenes with American actors.
