“Geophysicist Dr. Tadokoro and his assistants have discovered
abnormal fragmentations under the open sea of Izu. There is enough data to
believe that a big disaster, the Japanese islands sinking into the sea, will
occur within 2 years. Initially skeptical, the Japanese Government decides upon
an evacuation, i.e. 'Plan D'. However, the destruction is beyond Dr. Tadokoro's
estimation! Now, tremendous earthquakes occur everywhere in Japan, while
extinct volcanoes become active again. "Plan D" is put into action.
