Koji Suzuki, the Japanese author known for horror novels including “Ring,” died at a Tokyo hospital Friday. He was 68.

“Rakuen” (Paradise), his debut novel, received the Superior Award at the 1990 Japan Fantasy Novel Awards.

“Ring,” released in 1991, was adapted into movies in and outside Japan, becoming major hits. Suzuki thus came to be seen as a leading figure in a Japanese horror boom.

His works received domestic and international acclaim. “Rasen” (Spiral) won the Eiji Yoshikawa literary award for newcomers in Japan, while “Edge” received the Shirley Jackson Award in the United States.

Other major works include “Honogurai Mizu no Soko kara” (Dark Water), “Kamigami no Promenade” (Promenade of the Gods) and “Ubiquitous.”
