Eli K.P. William has spent his entire adult life in Japan making a career out of story and language. The only member of the Science Fiction and Fantasy Writers of Japan who writes novels in English, he is the author of The Jubilee Cycle trilogy (Skyhorse Publishing), set in a dystopian future Tokyo. The series includes Cash Crash Jubilee (2015) and The Naked World (2017), and concluded in 2023 with the final book A Diamond Dream. He translates Japanese literature, including the Yomiuri Prize winning novel A Man (Crossing 2020) by Keiichiro Hirano and the bestselling essay collection The Traveling Tree by Michio Hoshino.

In recent years, Eli also writes professionally in Japanese, serving as a bilingual story consultant for a major Tokyo-based video game company and contributing short stories to such publications as SF Prologue Wave and a 2025 anthology put out by Hayakawa, Japan’s largest and oldest sci-fi publisher. His translations, essays, and short stories have appeared in Aeon, Granta, The Southern Review, Monkey, The Malahat Review, The Japan Times, Tor.com, Kyoto Journal, Writer’s Digest, Nippon.com, Subaru, and more. In addition to the SFWJ, he is a member of both the Science Fiction and Fantasy Writers Association (SFWA) and The Writers Union of Canada (TWUC).

Born and raised in Toronto, Eli visited Tokyo for the first time as a university student and decided to move there upon graduation. After ten years in the thick of the metropolis, he now lives in the green hills nearby with his wife and daughter. On his free time, he enjoys listening to electronic music, street dancing, cycling, hiking, and deep conversation. His current projects include curating an anthology of classic Japanese SF short stories for MIT Press and researching for a planned near future novel.
