Fukuzumi set what proved to be the day's benchmark time of 1m17.827s just under halfway through the two-hour morning session at the wheel of the #16 Honda NSX-GT he shares with new team-mate Hiroki Otsu.
That was around 1.6 seconds slower than the best time set in manufacturer testing at Okayama in early February, but with the important caveat of this being the first test of the year in which the use of carbon-neutral fuel is mandatory.
