The 2015 Japanese Championship Super Formula season was the forty-third season of premier Japanese open-wheel motor racing and the third under the name of Super Formula. The season began on 19 April and will end on 8 November after seven rounds.
The 2015 season was also the last season that Bridgestone, who had been the series' only tyre supplier since 1997, supplied tyres to all teams, as Yokohama took over the tyre contract for 2016.
