He is the first Japanese driver to enter a Formula One World Championship Grand Prix, and the first to compete in the 24 Hours of Le Mans endurance race.

After leaving Toyota following the 1969 season, he began racing in America, competing in the SCCA Continental Championship, Canadian-American Challenge Cup, and the Trans-Am Series.

Fushida, along with fellow countryman Tetsu Ikuzawa, made history when they became the first Japanese drivers to compete at Le Mans in 1973, driving the Mazda rotary-powered Sigma MC73.

He unsuccessfully entered two Formula One Grands Prix with Maki, the first in The Netherlands at Zandvoort in 1975, where a blown engine prevented him from starting the race.

As operations director of RTN, Fushida oversaw the Bentley Speed 8's winning effort in the 2003 24 Hours of Le Mans.
