Masami Hirosaka of Tokyo, Japan, is the world's most successful radio control driver with a record fourteen IFMAR World Championships to his credit.
An active participant in radio controlled racing since the age of seven, Hirosaka was introduced to the hobby by his father. One of the most popular draws at major R/C racing events, Hirosaka has earned the nickname "Master Masami," given to him by his peers.
Hirosaka currently races for Yokomo where he helps develop new cars with the aid of computers and tests the resulting prototypes.
In a 1998 interview with Germany's Wedge DTM magazine, Hirosaka listed his other hobbies as computers and theater.
