He made his literary debut after winning the All Yomimono Mystery Prize for New Writers for "Ikebukuro West Gate Park" in 1997. Set largely in contemporary Tokyo, his fiction addresses youth crime, poverty, romance, sexuality, and generational division through a fast-paced and accessible narrative style.

Tetsuro, Dai, Jun, and Naoto, who has a premature-aging disorder, rely on their friendship as they confront romance, sexuality, family problems, violence, illness, and death on their way toward their fifteenth birthdays.
