Including official tests, Otsu has now sampled all but two of the Honda-powered outfits during the 2023 campaign, the 29-year-old having already driven for Dandelion Racing, Team Mugen and B-Max Racing so far in 2023 in his role as Honda's reserve driver.
The circumstances surrounding Otsu's second call-up to a race seat were somewhat less dramatic compared to last time, when he was parachuted into the car vacated by Tomoki Nojiri at Autopolis after the two-time champion suffered a collapsed lung on the Friday of race week.
