A lack of commitment from major Japanese teams, especially those involved in Super GT, meant that the entry list for the season was small.
An official pre-season test at Sportsland Sugo saw only 8 cars showing up.
LMP1 was able to boast some machinery that fit LMP rules with a Zytek 05S while there was promise of a new Courage LC70 for Mugen Motorsports on the way as the season went on.
GT2 was also only able to claim a few competitive entries, with some two Porsche 911 GT3s being mixed with a privateer cars that did not fully reach ACO GT2 specs.
For classes with a lower car count, the top five were awarded points in the order of 5-4-3-2-1.
