Koji Suzuki was born in 1957 in Hamamatsu, southwest of Tokyo. He attended Keio University where he majored in French. After graduating he held numerous odd jobs, including a stint as a cram school teacher. Also a self-described jock, he holds a first-class yachting license and crossed the U.S., from Key West to Los Angeles, on his motorcycle.

The father of two daughters, Suzuki is a respected authority on childrearing and has written numerous works on the subject. He acquired his expertise when he was a struggling writer and househusband. Suzuki also has translated a children's book into Japanese, The Little Sod Diaries by the crime novelist Simon Brett.

In 1990, Suzuki's first full-length work, Paradise won the Japanese Fantasy Novel Award and launched his career as a fiction writer. Ring, written with a baby on his lap, catapulted him to fame, and the multi-million selling sequels Spiral and Loop cemented his reputation as a world-class talent. Often called the Stephen King of Japan, Suzuki has played a crucial role in establishing mainstream credentials for horror novels in his country. He is based in Tokyo but loves to travel, often in the United States.
