Hirotoki Onozawa (小野澤 宏時, Onozawa Hirotoki, born March 29, 1978 in Shimada, Shizuoka, Japan) is a rugby union player who plays at Wing or occasionally Fullback for Canon Eagles. He previously played for Suntory Sungoliath and the Japan national rugby union team. Nicknamed "the eel" for his sharp sidestepping ability, Onozawa is the second most capped Japanese rugby player of all time, and fifth highest try scorer in international rugby. Despite spending much of his career in the shadow of Daisuke Ohata he is considered an all-time great of Japanese rugby in his own right.
