# Japan Sinks

Japan Sinks (Japanese: 日本沈没, Hepburn: Nippon Chinbotsu) is a disaster novel by Japanese writer Sakyo Komatsu, published in 1973.

## Overview

Komatsu took nine years to complete the work. It was published in two volumes, both released at the same time. The novel received the 27th Mystery Writers of Japan Award and the Seiun Award for a Japanese novel-length work. The English translation was first published in 1975. In 1995, after the Osaka-Kobe earthquake, a second English edition (ISBN 4-7700-2039-2) was published. The English translation is abridged. In 2006, a sequel to the novel, co-authored with Kōshū Tani, was published.
The novel has led to works in other media as well as a sequel: a film based on the novel made in the same year directed by Shirō Moritani, a manga adaptation written by Takao Saito and published in Weekly Shōnen Champion in 1973–74, a television drama by TBS and Toho broadcast in 1974–75, a film remake in 2006 by Shinji Higuchi, a parody created in 2011 that features reverse disaster, an original net anime series released on Netflix by Science Saru in July 2020, and a reboot drama, Japan Sinks: People of Hope, broadcast in October 2021 on TBS.

### Geophysical background

Japan is on a destructive plate boundary, where the Philippine Sea Plate subducts the Eurasian Plate. It is a triple junction and three subduction zones are involved. After the 2011 Tōhoku earthquake and tsunami, towns like Ishinomaki subsided.

### Political background

This novel is now seen as an important look into the cultural context of 1970s Japan, particularly due to its level of popularity.

The series, titled Japan Sinks: 2020, was animated by Science Saru, with Ho Pyeon-gang and Masaaki Yuasa served as directors.
