All Japan GT Championship was introduced in 1993 after death of exciting group C cars. In the early years of the championship we could see here also some prototypes, such as Nissan R91CK, Spice or Porsche 962C and some European GT series or IMSA GTS participants as well as cars from Japan Sport Sedan Series. The only genuine JGTC participants in 1993 season were two Nissans entered by NISMO. But early GT championship in Japan got his typical look with Skylines, Supras, NSXs and Porsche GTs on top positions. There are about forty starting cars in each race.
