In 1949 Komatsu wrote the manga by the name Minoru Mori. His career as a writer began in the 1960s. Reading Kōbō Abe and Italian classics made Komatsu feel modern literature and science fiction are the same.

In 1961 he wrote his first fantastic story 'Peace on Earth' for the Scientific-fiction Contest of SF Magazine. It was the story about a world in which World War II does not end in August 1945 and a young man prepares to defend Japan against the Allied invasion.

Komatsu’s most famous novel was 'Japan Sinks', in which the shifting of the tectonic plates resulted in earthquakes across the entire nation and causes all of Japan to crumble into the sea. The book was published in March, 1973 and became a hit, selling over 4 million copies only in Japan. It was translated into more than a dozen different languages, and received positive reviews from foreign press like The New York Times and The Christian Science Monitor. A second edition appeared in the US in the aftermath of the 1995 Kobe Earthquake with a new opening statement by the author.

Komatsu was haunted by memories from his teenage years of the devastation caused by the atomic bombs dropped on Hiroshima and Nagasaki.

He was inspired to write thinking of what would happen if the nationalistic Japanese lost their land, and ironically prefigured the 2011 Tōhoku earthquake and tsunami that triggered a nuclear plant disaster decades later on March 11, 2011.

Quotations: "In a world suffused by nationalism and ethnicity, he said, “I began to think how people in Japan would live if they lost their land,” adding, “I sometimes wonder if our intolerant territoriality is really justifiable on this planet, where continents are constantly drifting.”

Few days before his death, quarterly publication 'Sakyo Komatsu Magazine' released an issue featuring an article on his thoughts about the 2011 tsunami:

“I had thought I wouldn’t mind dying any day. But now I’m feeling like living a little bit longer and seeing how Japan will go on hereafter.”
