The 1992 All Japan Sports Prototype Car Endurance Championship was the tenth and final season of the All Japan Sports Prototype Championship, which would be replaced by the All Japan Grand Touring Car Championship, as sportscar racing in the early 1990s changed drastically with the decline of prototypes. The C1 class champion was the #1 Nissan Motorsports Nissan R92CP driven by Kazuyoshi Hoshino and the C class champion was the #7 and #36 TOM'S Toyota TS010 driven by Geoff Lees.
