Japan Sinks is a calamity novel by Sakyo Komatsu, distributed in 1973. Komatsu took nine years to finish the work. The distributer needed it to be written in two unique segments, both distributed simultaneously. The tale got the 27th Mystery Writers of Japan Award and the Seiun Award for a Japanese novel length work.

The novel has prompted works in other media just as continuations: a movie dependent on the novel was made around the same time coordinated by Shiro Moritani, a network show made in 1975, a change in 2006 by Shinji Higuchi.
In 1995, after the Osaka-Kobe quake, Komatsu distributed a subsequent English abbreviated version (ISBN 4-7700-2039-2). In 2006, a continuation of the novel was distributed and there is discussion of a third.
