Yamashita was at the wheel of the Rookie Racing Toyota GR Supra when he suffered an off at the high-speed 130R corner and hit the barriers at speed late in the opening session of the two-day test.
The 27-year-old was taken to hospital following the incident but his team announced he had escaped serious injury.
Now Rookie Racing has confirmed that Yamashita left hospital on Wednesday following an overnight stay.
While Yamashita himself emerged from the crash relatively unscathed, Rookie faces a major repair job to prepare its damaged GR Supra for its next planned test outing at Okayama on February 8-9.
Second day of Suzuka test snowed off
Heavy snowfall at Suzuka meant that the second day of the opening makers' test of 2023 had to be called off.
Tuesday's running had been extended from four hours to six hours (split into a pair of three-hour sessions) owing to the poor weather forecast, with only two hours of track time planned for Wednesday afternoon. However, such were the conditions that this session was quickly called off.
