Yamashita suffered a major crash at Suzuka's 130R corner on the opening day of manufacturer testing aboard the Rookie Racing Toyota GR Supra, and had to be taken to hospital.
He was released the following day to begin his rehabilitation, but has not driven a racing car since, missing last week's Suzuka SUPER GT test and this week's Super Formula test at the same track. He will also skip this week's first official pre-season SUPER GT test at Okayama.
